This VLAN scenario often occurs in a service-provider network in which you configure VLAN tags for trafficfrom multiple customers on customer-premises equipment (CPE), and separate VRF instances associatedwith each VLAN are configured on the provider edge (PE) router in the point-of-presence (POP).VRRP in VRF: Switch-1 VLAN ConfigurationS1(conf)#ip vrf VRF-1 1!S1(conf)#ip vrf VRF-2 2!S1(conf)#ip vrf VRF-3 3!S1(conf)#interface TenGigabitEthernet 2/4S1(conf-if-te-2/4)#no ip addressS1(conf-if-te-2/4)#switchportS1(conf-if-te-2/4)#no shutdown!S1(conf-if-te-2/4)#interface vlan 100S1(conf-if-vl-100)#ip vrf forwarding VRF-1S1(conf-if-vl-100)#ip address 10.10.1.5/24S1(conf-if-vl-100)#tagged tengigabitethernet 2/4S1(conf-if-vl-100)#vrrp-group 11% Info: The VRID used by the VRRP group 11 in VRF 1 will be 177.S1(conf-if-vl-100-vrid-101)#priority 100S1(conf-if-vl-100-vrid-101)#virtual-address 10.10.1.2S1(conf-if-vl-100)#no shutdown!S1(conf-if-te-2/4)#interface vlan 200S1(conf-if-vl-200)#ip vrf forwarding VRF-2S1(conf-if-vl-200)#ip address 10.10.1.6/24S1(conf-if-vl-200)#tagged tengigabitethernet 2/4S1(conf-if-vl-200)#vrrp-group 11% Info: The VRID used by the VRRP group 11 in VRF 2 will be 178.S1(conf-if-vl-200-vrid-101)#priority 100S1(conf-if-vl-200-vrid-101)#virtual-address 10.10.1.2S1(conf-if-vl-200)#no shutdown!S1(conf-if-te-2/4)#interface vlan 300S1(conf-if-vl-300)#ip vrf forwarding VRF-3S1(conf-if-vl-300)#ip address 20.1.1.5/24S1(conf-if-vl-300)#tagged tengigabitethernet 2/4S1(conf-if-vl-300)#vrrp-group 15% Info: The VRID used by the VRRP group 15 in VRF 3 will be 243.S1(conf-if-vl-300-vrid-101)#priority 255S1(conf-if-vl-300-vrid-101)#virtual-address 20.1.1.5S1(conf-if-vl-300)#no shutdownVRRP in VRF: Switch-2 VLAN ConfigurationS2(conf)#ip vrf VRF-1 1!S2(conf)#ip vrf VRF-2 2!S2(conf)#ip vrf VRF-3 3!S2(conf)#interface TenGigabitEthernet 2/4S2(conf-if-te-2/4)#no ip addressS2(conf-if-te-2/4)#switchportS2(conf-if-te-2/4)#no shutdown!S2(conf-if-te-2/4)#interface vlan 100S2(conf-if-vl-100)#ip vrf forwarding VRF-1Virtual Router Redundancy Protocol (VRRP) 1238
