VRRP in a VRF: Non-VLAN Scenario
The following example shows how to enable VRRP in a non-VLAN.
The following example shows a typical use case in which you create three virtualized overlay networks by configuring three VRFs in
two switches. The default gateway to reach the Internet in each VRF is a static route with the next hop being the virtual IP address
configured in VRRP. In this scenario, a single VLAN is associated with each VRF.
Both Switch-1 and Switch-2 have three VRF instances defined: VRF-1, VRF-2, and VRF-3. Each VRF has a separate physical
interface to a LAN switch and an upstream VPN interface to connect to the Internet. Both Switch-1 and Switch-2 use VRRP groups
on each VRF instance in order that there is one MASTER and one backup router for each VRF. In VRF-1 and VRF-2, Switch-2 serves
as owner-master of the VRRP group and Switch-1 serves as the backup. On VRF-3, Switch-1 is the owner-master and Switch-2 is
the backup.
In VRF-1 and VRF-2 on Switch-2, the virtual IP and node IP address, subnet, and VRRP group are the same. On Switch-1, the virtual
IP address, subnet, and VRRP group are the same in VRF-1 and VRF-2, but the IP address of the node interface is unique. There is
no requirement for the virtual IP and node IP addresses to be the same in VRF-1 and VRF-2; similarly, there is no requirement for the
IP addresses to be different. In VRF-3, the node IP addresses and subnet are unique.
