How to Configure MPLS VPNs over IP Tunnels

Configuring a CFI VRF Interface

Perform this task to associate a VPN routing and forwarding (VRF) instance with an interface or a subinterface on the PE routers.

SUMMARY STEPS

1.configure

2.interface type interface-id

3.vrf vrf-name

4.ipv4 address ipv4-address

5.ipv6 address ipv6-address

6.dot1q vlan vlan-id

7.end or commit

DETAILED STEPS

	Command or Action	Purpose
Step 1
	configure	Enters global configuration mode.
	Example:
	RP/0/RP0/CPU0:router# configure
Step 2
	interface type interface-id	Enters interface configuration mode and enables a
		GigabitEthernet interface.
	Example:
	RP/0/RP0/CPU0:router(config)# interface
	GigabitEthernet0/0/0/1.1
Step 3
	vrf vrf-name	Specifies a VRF name.
	Example:
	RP/0/RP0/CPU0:router(config-if)# vrf v1
Step 4
	ipv4 address ipv4-address	Enters an IPv4 address and mask for the associated IP
		subnet. The network mask can be specified in either of two
	Example:	ways:
	RP/0/RP0/CPU0:router(config-if)# ipv4 address	• The network mask can be a four-part dotted decimal
	100.1.10.2 255.255.255.0	address. For example, 255.0.0.0 indicates that each bit
		equal to 1 means that the corresponding address bit
		belongs to the network address.
		• The network mask can be indicated as a slash (/) and
		number. For example, /8 indicates that the first 8 bits of
		the mask are ones, and the corresponding bits of the
		address are network address.
