Configuring VRRP
The following procedure can be used to configure a simple
VRRP topology:
- Configure the VRRP IP address owner router as follows:
- Create a VLAN to serve as the VRRP router VLAN.
- Add an IP address to the VRRP VLAN.
- Enable IP forwarding on VRRP VLAN.
- Add the VRRP version for the VRRP instance (see Configuring VRRP Version Support).
- Create the VRRP router instance for the intended VRRP master (see Creating and Deleting VRRP Router Instances).
- Add the IP address defined in Step 1b as a VRRP router IP address (see Adding and Deleting VRRP Router IP Addresses).
- Enable VRRP on the switch (see Enabling and Disabling VRRP and VRRP Router Instances).
- Configure each backup VRRP router as follows:
- Create a VLAN to serve as the VRRP router VLAN. This name must match the name used for the appropriate VRRP IP address owner.
- 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.
- Enable IP forwarding on VRRP VLAN.
- Create the VRRP router instance that will serve as the backup instance (see Creating and Deleting VRRP Router Instances).
- Configure the priority for the backup VRRP router to a value in the range of 1–254 (see Configuring VRRP Router Priority).
- Add the same VRRP router IP address that was added to the intended VRRP master instance (see Adding and Deleting VRRP Router IP Addresses).
- 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.
