VRRP in a VRF Configuration

The following example shows how to enable VRRP operation in a VRF virtualized network for the

following scenarios.

Multiple VRFs on physical interfaces running VRRP.

Multiple VRFs on VLAN interfaces running VRRP.

To view a VRRP in a VRF configuration, use the show commands.

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 E-Series 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

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.
