Configuring VRRP

Configuring VRRP
To configure a router for VRRP, do the following:
1. Enable VRRP on the router.
2. Indicate the authentication method used for the interface on which you are configuring the VRID (optional).
VRRP uses the authentication method in use on the interface.
3. Add a VRID to an interface.
4. Indicate whether the router is the "owner" of the IP addresses you plan to associate with the VRID or a
Backup. If the router is not the owner of the IP address(es), the router is a Backup.
5. Enter the IP address(es) associated with the VRID. The IP addresses must already be configured on the
owner, on the same interface as the VRID. Additionally, the VRID interface on the Backup router must have at
least one interface in the same sub-net.
6. Disable RIP advertisements om the Backup routers for the backed up interface (optional).
7. Configure track ports (optional).
8. Change the Hello interval (optional).
9. Change the Dead interval (optional).
10. Disable the preempt mode (optional).
11. Activate the virtual router.
12. Repeat these steps for the other routers in the virtual router.
13. Save the VRRP configuration to the system configuration file.
NOTE: You initially enable VRRP at the global CONFIG level of the CLI using the router vrrp command. All other
parameters are assigned or modified at the interface level of the CLI using ip vrrp... commands.
If you are using the Web management interface, enable VRRP on the System configuration sheet. All other VRRP
parameters are configured on the VRRP configuration sheet.

Configuration Rules for VRRP

• The interfaces of all routers in a VRID must be in the same IP sub-net.
• The IP address(es) associated with the VRID must already be configured on the router that will be the owner
router.
• An IP address(es) associated with the VRID must be on only one router.
• The Hello interval must be set to the same value on both the owner and Backup router(s) in the virtual router.
• The Dead interval must be set to the same value on both the owner and Backup router(s) in the virtual router.
• The track priority on a router must be lower than the router's VRRP priority. Also, the track priority on the
owner must be higher than the track priority on the Backup router(s).

Enabling VRRP

Before configuring an interface for VRRP, you must enable the feature on the router.
USING THE CLI
To enable VRRP on a router, enter the following command. Enter the same command on each routing switch that
you are configuring for VRRP.
9300M(config)# router vrrp
syntax: router vrrp
