How to Configure MPLS VPNs over IP Tunnels

	Command or Action	Purpose
Step 18
	route-policyroute-policy-name out	Applies the pass-all policy to all outbound routes.
	Example:
	RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-af)#
	route-policy pass-all out
Step 19
	end	Saves configuration changes.
	or	• When you issue the end command, the system prompts
	commit	you to commit changes:
		Uncommitted changes found, commit them before
	Example:	exiting(yes/no/cancel)?
	RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-af)#	[cancel]:
	end	– Entering yes saves configuration changes to the
	or
	RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-af)#	running configuration file, exits the configuration
		session, and returns the router to EXEC mode.
	commit
		– Entering no exits the configuration session and
		returns the router to EXEC mode without
		committing the configuration changes.
		– Entering cancel leaves the router in the current
		configuration session without exiting or
		committing the configuration changes.
		• Use the commit command to save the configuration
		changes to the running configuration file and remain
		within the configuration session.

Verifying MPLS VPN over IP

To verify the configuration of end-end (PE-PE) MPLS VPN over IP provisioning, use the following show commands:

•show cef recursive-nexthop

•show bgp ipv4 tunnel

•show bgp vpnv4 unicast summary

•show bgp vrf v1 ipv4 unicast summary

•show bgp vrf v1 ipv4 unicast prefix

•show cef vrf v1 ipv4 prefix

•show cef ipv6 recursive-nexthop

•show bgp vpnv6 unicast summary

•show bgp vrf v1 ipv6 unicast summary

•show bgp vrf v1 ipv6 unicast prefix

•show cef vrf v1 ipv6 prefix
