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 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.
