Configuring Multi-VRF CE

	Command	Purpose
Step 9
	end	Return to privileged EXEC mode.
Step 10
	show ip vrf [brief detail interfaces]	Verify the configuration. Display information about the
	[vrf-name]	configured VRFs.
Step 11
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

Use the no ip vrf vrf-nameglobal configuration command to delete a VRF and to remove all interfaces from it. Use the no ip vrf forwarding interface configuration command to remove an interface from the VRF.

Configuring a VPN Routing Session

Routing within the VPN can be configured with any supported routing protocol (RIP, OSPF, EIGRP, or BGP) or with static routing. The configuration shown here is for OSPF, but the process is the same for other protocols.

Beginning in privileged EXEC mode, follow these steps to configure OSPF in the VPN:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	router ospf process-id vrf vrf-name	Enable OSPF routing, specify a VPN forwarding table,
		and enter router configuration mode.
Step 3
	log-adjacency-changes	(Optional) Log changes in the adjacency state. This is the
		default state.
Step 4
	redistribute bgp	Set the switch to redistribute information from the BGP
	autonomous-system-number subnets	network to the OSPF network.
Step 5
	network network-number area area-id	Define a network address and mask on which OSPF runs
		and the area ID for that network address.
Step 6
	end	Return to privileged EXEC mode.
Step 7
	show ip ospf process-id	Verify the configuration of the OSPF network.
Step 8
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

Use the no router ospf process-idvrf vrf-nameglobal configuration command to disassociate the VPN forwarding table from the OSPF routing process.
