This VLAN scenario often occurs in a service-provider network in which you configure VLAN tags for traffic from multiple
customers on customer-premises equipment (CPE), and separate VRF instances associated with each VLAN are configured on
the provider edge (PE) router in the point-of-presence (POP).

VRRP in VRF: Switch-2 VLAN Configuration
VRRP for IPv6 Configuration
This section shows VRRP IPv6 topology with CLI configurations.
Consider an example VRRP for IPv6 configuration in which the IPv6 VRRP group consists of two routers.
Figure 175. VRRP for IPv6 Topology
NOTE:
This example does not contain comprehensive directions and is intended to provide guidance for only a typical VRRP
configuration. You can copy and paste from the example to your CLI. Be sure you make the necessary changes to support
your own IP addresses, interfaces, names, and so on.
NOTE: In a VRRP or VRRPv3 group, if two routers come up with the same priority and another router already has MASTER
status, the router with master status continues to be master even if one of two routers has a higher IP or IPv6 address.
