How to Configure MPLS VPNs over IP Tunnels

	Command or Action	Purpose
Step 9
	route-policyroute-policy-name {out}	Applies a routing policy to updates that are sent from a BGP
		neighbor.
	Example:	• Use the route-policy-nameargument to define the name
	RP/0/0/CPU0:router(config-bgp-nbr-af)#	of the of route policy. The example shows that the route
	route-policy pass-all out	policy name is defined as pass-all.
		• Use the out keyword to define the policy for outbound
		routes.
Step 10
	neighbor ip-address	Places the router in neighbor configuration mode for BGP
		routing and configures the neighbor IP address 175.40.25.2
	Example:	as an VPNv4 iBGP peer.
	RP/0/0/CPU0:router(config-bgp-nbr-af)# neighbor
	175.40.25.2
	RP/0/0/CPU0:router(config-bgp-nbr)#
Step 11
	remote-asautonomous-system-number	Creates a neighbor and assigns it a remote autonomous
		system number.
	Example:
	RP/0/0/CPU0:router(config-bgp-nbr)# remote-as
	2002
Step 12
	update-sourceinterface-type interface-number	Allows BGP sessions to use the primary IP address from a
		particular interface as the local address.
	Example:
	RP/0/0/CPU0:router(config-bgp-nbr)#
	update-source loopback0
Step 13
	address-family {ipv4 tunnel}	Configures IPv4 tunnel address family.
	Example:
	RP/0/0/CPU0:router(config-bgp-nbr)#
	address-family ipv4 tunnel
	RP/0/0/CPU0:router(config-bgp-nbr-af)#
