CONFIGURING ROUTER REDUNDANCY

Configuring Router Redundancy

Router redundancy protocols use a virtual IP address to support a primary router and multiple backup routers. The backup routers can be configured to take over the workload if the master router fails, or can also be configured to share the traffic load. The primary goal of router redundancy is to allow a host device which has been configured with a fixed gateway to maintain network connectivity in case the primary gateway goes down.

This switch supports both the Virtual Router Redundancy Protocol (VRRP) and Hot Standby Router Protocol (HSRP). These protocols are very similar. The primary difference is that VRRP requires you to specify the interface of one of the routers participating in the virtual group as the address for the master virtual router, while HSRP requires you to configure an arbitrary address for the virtual master router. Both protocols then select the backup routers based on the specified virtual router priority. HSRP also includes the ability to dynamically modify the virtual router priority based on the operational state of other interfaces on the router.

Router redundancy can be set up in any of the following configurations. The following examples show configuration settings for VRRP. The only difference for HSRP is that the virtual router IP address is never a real address, and the master router is selected based on priority only.
