How do I configure HSRP between two routers?

How do I configure HSRP between two routers?

To achieve basic HSRP configuration, you need to do the following:

  1. Configure normal IP address on interface (cannot be the same as HSRP virtual IP)
  2. Bring interface up (no shutdown)
  3. Configure HSRP group and virtual IP address using the standby command.

What is the default priority of a router in HSRP?

100
The default HSRP priority is 100. If you want an HSRP router to be elected as the active router, you should set the priority to a value higher than the default of 100.

What is the command to check HSRP status?

Showing HSRP State Information

  1. Problem. You want to see current HSRP information, such as which router is primary.
  2. Solution. To view the HSRP information, use the following EXEC command: Router2# show standby.
  3. Discussion.

Can a router recognize more than one HSRP address?

In most cases, when you configure routers to be part of an HSRP group, the routers listen for the HSRP MAC address for that group as well as their own BIA. The only exception to this behavior is for Cisco 2500, 4000, and 4500 routers. These routers have Ethernet hardware that only recognizes a single MAC address.

What happens if the standby router does not run HSRP?

This router is known as the active router. Another router is elected as the standby router. If the active router fails, the standby assumes the packet forwarding duties. Although an arbitrary number of routers may run HSRP, only the active router forwards the packets that are sent to the virtual router IP address.

Can a HSRP be used as a gateway address?

Using HSRP, the two routers will have a physical IP address configured on their LAN-facing interface, but they will have also a Virtual (HSRP address) which will be used as the default gateway address for hosts on the LAN.

Where does the hello packet come from in HSRP?

The active router sources hello packets from its configured IP address and the HSRP virtual MAC address. The standby router sources hellos from its configured IP address and the burned-in MAC address (BIA). This use of source addressing is necessary so that HSRP routers can correctly identify each other.
