Configuring VRRP

The following procedure can be used to configure a simple VRRP (Virtual Router Redundancy Protocol) topology:

Configure the VRRP IP address owner router as follows:
1. Create a VLAN (Virtual LAN) to serve as the VRRP router VLAN.
2. Add an IP address to the VRRP VLAN.
3. Enable IP forwarding on VRRP VLAN.
4. Add the VRRP version for the VRRP instance (see Configuring VRRP Version Support).
5. Create the VRRP router instance for the intended VRRP master (see Creating and Deleting VRRP Router Instances).
6. Add the IP address defined in Step 1b as a VRRP router IP address (see Adding and Deleting VRRP Router IP Addresses).
7. Enable VRRP on the switch (see Enabling and Disabling VRRP and VRRP Router Instances).
Configure each backup VRRP router as follows:
1. Create a VLAN to serve as the VRRP router VLAN. This name must match the name used for the appropriate VRRP IP address owner.
2. Add an IP address to the VRRP VLAN. This address must be different from the IP address assigned to the intended VRRP master, but it must use the same subnet.
3. Enable IP forwarding on VRRP VLAN.
4. Create the VRRP router instance that will serve as the backup instance (see Creating and Deleting VRRP Router Instances).
5. Configure the priority for the backup VRRP router to a value in the range of 1–254 (see Configuring VRRP Router Priority).
6. Add the same VRRP router IP address that was added to the intended VRRP master instance (see Adding and Deleting VRRP Router IP Addresses).
7. Enable VRRP on the switch (see Enabling and Disabling VRRP and VRRP Router Instances).
Configure network workstations to use the VRRP router IP address as the default gateway address.
