How to Configure Hsrp on Cisco Layer 3
HSRP is a Cisco proprietary protocol that provides redundancy for IP networks. If one router fails, the other router takes over and continues to route traffic. HSRP is transparent to users and applications, so they are unaware of any change in the routing path.
Configuration of HSRP is simple and only requires a few commands. In this article, we will show you how to configure HSRP on Cisco Layer 3 switches.
L3 Switching: HSRP Configuration
- Navigate to the interfaces configuration page in your Cisco router web interface
- Find the interface you want to configure HSRP for and select it
- Enter the HSRP group number you want to use for this interface in the “Group” field
- Select the “Standby” role for this interface in the “Role” field
- Enter the IP address you want to use for this interface in the “Standby IP Address” field
- Enter the priority you want to use for this router in the “Priority” field (255 is highest priority, 0 is lowest)
- Save your changes and exit from the web interface
How to Configure Hsrp on Cisco Layer 3 Switch
HSRP is a Cisco proprietary redundancy protocol that is used to establish a fault-tolerant default gateway. When multiple HSRP-compatible devices are connected in a network, they will elect one device as the active router and the other(s) will be in standby mode. If the active router fails, one of the standby routers will take over and assume the role of active router.
To configure HSRP on a Cisco Layer 3 switch, you need to first enable IP routing on the switch. This can be done by going into global configuration mode and issuing the “ip routing” command. Once IP routing has been enabled, you can create an HSRP group and specify the priority, preemption delay, and authentication password for that group.
To do this, go into interface configuration mode for the desired interface and issue the “standby
Finally, you can optionally set an authentication password for your HSRP group by using the “standby
How to Configure Hsrp With Multiple Vlans
If you have a router that supports HSRP and multiple VLANs, you can configure HSRP to provide redundancy for each VLAN. In this article, we’ll show you how to do just that.
To begin, let’s take a look at the topology we’ll be using:
As you can see, we have two routers – R1 and R2 – connected to two switches. Each switch has two VLANs configured on it – VLAN 10 and VLAN 20. Our goal is to configure HSRP so that if one of the routers goes down, traffic on both VLANs will still be able to reach its destination.
We’ll start by configuring HSRP on Router 1. We’ll use the following commands:
interface FastEthernet0/0
description Uplink to Switch 1
no shutdown
!
interface FastEthernet0/1
description Uplink to Switch 2
no shutdown
!
interface vlan 10
ip address 10.10.10.1 255.255.255.0
standby version 2
standby 10 ip 10.10.10.254
priority 120
!
interface vlan 20
ip address 10 .20 .20 .1 255 .255 .255 .0

Introduction
The Hot Standby Router Protocol (HSRP) is a Cisco-proprietary first hop redundancy protocol that is used to establish a fault-tolerant default gateway.
HSRP is supported on most Cisco routers and switches and can be used in conjunction with other first-hop redundancy protocols such as Virtual Router Redundancy Protocol (VRRP) and Gateway Load Balancing Protocol (GLBP).
When configuring HSRP, two or more devices are configured with the same group number. One device in the group is elected as the active router and another device is elected as the standby router.
The active router is responsible for forwarding traffic to and from the default gateway IP address. The standby router takes over as the active router if the current active router fails or becomes unavailable.
In order to use HSRP, you must configure a unique IP address on each participating device in the same subnet as the default gateway IP address.
This IP address is referred to as the HSRP virtual IP address. Traffic destined for the default gateway IP address will be forwarded to the HSRP virtual IP address, which will then be forwarded to the active router.
Configuring an SVI for Use with HSRP
In order for HSRP to function properly, you must configure a unique IP address on each participating device in addition to configuring interfaces for each VLAN that will be using HSRP . This document describes how to configure an interface so that it may participate in HSRP . For information about configuring other aspects of HSRP , refer to Introduction .
When configuring an interface for use with HSRP , you must specify both an IPv4address and an IPv6address . You can optionally specify a priority value , which determines whichdevice becomestheactiverouter . If no priority valueis specified,theactive router is chosen basedon highestIPv6addressamongsttheparticipatingdevices .

Hsrp Configuration in Cisco Switch
HSRP is a Cisco proprietary protocol that provides redundancy for IP networks. It is commonly used in conjunction with the Virtual Router Redundancy Protocol (VRRP) to provide failover between two routers. When configuring HSRP, you must specify an interface that will be used to send and receive HSRP packets.
You also need to specify a priority value for each router. The router with the highest priority will be elected as the active router and will handle all traffic. If the active router fails, the standby router will take over and begin forwarding traffic.
To configure HSRP on a Cisco switch, you need to do the following:
1) Configure an interface to be used for HSRP:
interface fastEthernet 0/1
hsrp version 2 ; This line is only needed if your devices are running IOS 15 or later
ip address 10.0.0.1 255.255.255.0
hsrp 100 ; This is the group number; can be any number from 0-255
preempt delay minimum 30 seconds ; These lines are optional; see below for more information about them
priority 110 ; The higher the priority, the more likely this device will become active
2) Specify a priority value for each router:
router bgp 100 ; Change this line to reflect your own AS number
Cisco Hsrp Configuration Example
If you’re looking for a Cisco HSRP configuration example, look no further. This blog post will provide you with all the information you need to get started.
HSRP, or Hot Standby Router Protocol, is a redundancy protocol that is commonly used on Cisco routers.
It allows two or more routers to work together so that if one router fails, the other can take over. This ensures that there is no downtime in your network.
To configure HSRP on your Cisco router, you need to first enable the protocol.
You can do this by entering the following command:
router(config)#standby 1 ip 10.0.0.1
This will enable HSRP on your router and assign it an IP address of 10.0.0.1 .
You can then add additional routers to your group by using the standby 1 priority command. The priority value can be between 0 and 255 , with 0 being the highest priority and 255 being the lowest priority . By default, all routers have a priority of 100 .
So, if you want RouterA to be the primary router and RouterB to be the backup router, you would use the following commands:
RouterA(config)#standby 1 priority 110 RouterB(config)#standby 1 priority 120
Once you’ve configured your priorities, you’ll need to specify what interface each router should use for HSRP traffic .
You can do this with the standby 1 interface command . For example: RouterA(config-if)#standby 1 interface fastEthernet 0/0 RouterB(config-if)#standby 1 interface fastEthernet 0/0
Finally, you’ll need to specify a virtual IP address that will be used by all routers in the group .
This is done with the standby 1 vip command .

Is Hsrp a Layer 3?
HSRP, or the Hot Standby Routing Protocol, is a Layer 3 redundancy protocol that is used to maintain continuous network connectivity in the event of a router failure. The protocol allows for two or more routers to be configured as primary and backup devices, with the backup router taking over seamlessly in the event of a failure. HSRP is designed to work with any routed protocols and can be easily implemented into existing network infrastructure.
How Do I Configure Hsrp Protocol?
HSRP, or the Hot Standby Router Protocol, is a Cisco-proprietary redundancy protocol that is used to establish a fault-tolerant default gateway. In an HSRP group, there are two types of devices: active and standby. The active device is the one that is currently forwarding traffic, while the standby device is on standby, ready to take over if the active device fails.
To configure HSRP, you need to first enable it on the interface that will be participating in the group. This can be done with the “standby” interface command. Once HSRP is enabled, you will need to specify the priority of the device using the “standby priority” command.
The higher the priority, the more likely it is that a device will become active. You also need to specify an HSRP group number using the “standby group” command.
After specifying the priority and group number, you then need to specify what IP address will be used as the virtual router’s IP address using t he “standby ip” command.
Once this is done, HSRP should be up and running on your interface!
Can We Configure Hsrp on L2 Switch?
In short, the answer is yes you can configure HSRP on a L2 switch. Here is some more detailed information on how it works.
HSRP is a protocol that provides redundancy for IP traffic.
In the event of primary router failure, the secondary router takes over and continues providing service. HSRP uses multicast address 224.0.0.2 and UDP port 1985.
Configuring HSRP on a L2 switch involves creating an HSRP group and then configuring individual interfaces to use that group.
The priority value determines which router will be the active one – the higher the priority, the more likely it is to become active. You can also configure preemption, which means that if the active router fails, another router with a lower priority can take over automatically.
One important thing to note about configuring HSRP on a L2 switch is that you need to make sure all of your routers are in sync – otherwise they will not be able to communicate properly and provide failover correctly.
You can do this by using Cisco’s IOS synchronization feature or by manually configuring each router with the same settings.
How Do I Configure Hsrp between Two Routers?
HSRP is a Cisco proprietary protocol that allows for the creation of a virtual router. This virtual router can be used to provide redundancy and high availability for IP networks. HSRP uses a priority system to determine which router will be the active router.
The active router is responsible for forwarding traffic while the standby router takes over if the active router fails.
To configure HSRP between two routers, you must first enable the HSRP feature on both routers. You can do this by entering the “feature hsrp” command in configuration mode.
Next, you will need to create an HSRP group and assign it a priority. The group number must be identical on both routers so that they know which group they are in. The priority value determines which router will be the active router.
The higher the priority value, the more likely it is that a given router will become the active one.
Once you have created an HSRP group, you need to specify what interface each group should use.
Conclusion
If you’re working with Cisco devices, it’s likely that you’ll need to configure the Hot Standby Router Protocol (HSRP) at some point. HSRP is a protocol that allows for failover between two routers in case one goes down. In this blog post, we’ll show you how to configure HSRP on a Cisco layer 3 device.
First, you’ll need to enable the HSRP feature on the router:
Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#feature hsrp %HSRP: Already enabled Router1(config)#exit
Next, you’ll need to create an HSRP group and specify the priority of each router. The router with the higher priority will be the active router.
In this example, we’ll give Router1 a priority of 100 and Router2 a priority of 50:
