How do I configure HSRP on my router?
Table of Contents
Configure HSRP version 2 between R1 and R2 using the IP addresses 10.10. 10.1/24 (R1) and 10.10. 10.2/24(R2) and a virtual IP address of 10.10….Table 3 – R2 Example Configuration.
| 1 | Enter privileged EXEC mode. | R2>enable |
|---|---|---|
| 9 | Configure the HSRP virtual IP address. | R2(config-if)#standby ip 10.10.10.5 |
How do I enable HSRP on my Cisco router?
To configure HSRP, issue the standby [group-number] ip [ip-address] command and assign the virtual IP address for a group. Use the same group number and virtual IP address on other routers, which provide redundancy for that group. This is the only command that is necessary to enable HSRP.
How do I find the HSRP on my Cisco router?
Showing HSRP State Information
- Problem. You want to see current HSRP information, such as which router is primary.
- Solution. To view the HSRP information, use the following EXEC command: Router2# show standby.
- Discussion.
How does Cisco HSRP work?
HSRP works by the exchange of multicast messages that advertise priority among the HSRP group. When the active router fails to send a hello message within a configurable period of time, the standby router with the highest priority becomes the active router.
How do I set HSRP priority?
To configure Hot Standby Router Protocol (HSRP) priority, use the hsrp priority command in HSRP interface configuration mode. To restore the default values, use the no form of this command.
How do I know if my router is HSRP active?
Question: Which value is used to determine the active router in an HSRP default configuration? Explanation: In the case of an equal priority, the router with the highest IP address for the respective group is elected as active.
What are two purposes of HSRP?
It provides a continuous network connection when a router fails. It prevents a rogue switch from becoming the STP root. It enables an access port to immediately transition to the forwarding state.
How many routers can participate in HSRP?
HSRP allows you to configure two or more routers as standby routers and only a single router as an active router at a time. All the routers in a single HSRP group shares a single MAC address and IP address, which acts as a default gateway to the local network.
What is the default priority of HSRP?
100
Priority is determined first by the value that is configured at the interface, and then by highest interface IP address. Default priority is set to 100. Changing standby priority will not take any results as long as preempt is not enabled.
Is HSRP Cisco proprietary?
In computer networking, the Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway. Version 1 of the protocol was described in RFC 2281 in 1998.
Why do we need HSRP Cisco?
The quick definition: Hot Standby Router Protocol (HSRP) is a Cisco protocol that provides host devices with redundant connectivity in a network. In other words, it’s an automatic backup system. If connectivity fails on the primary router, then it’ll immediately failover to a standby router.
