Implementing MPLS VPNs over IP Tunnels on Cisco IOS XR Software

How to Configure MPLS VPNs over IP Tunnels

	Command or Action	Purpose
Step 5
	neighbor A.B.C.D	Configures the IP address for the BGP neighbor.
	Example:
	RP/0/RP0/CPU0:router(config-bgp-af)# neighbor
	10.10.10.0
	RP/0/RP0/CPU0:router(config-bgp-nbr)#
Step 6
	remote-as as-number	Configures the AS number for the BGP neighbor.
	Example:
	RP/0/RP0/CPU0:router(config-bgp-nbr)# remote-as
	888
Step 7
	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/RP0/CPU0:router(config-bgp-nbr)#
	update-source loopback0
Step 8
	address-family {vpnv4 unicast}	Configures VPNv4 unicast address family.
	Example:
	RP/0/RP0/CPU0:router(config-bgp-nbr)#
	address-family vpnv4 unicast
	RP/0/RP0/CPU0:router(config-bgp-nbr-af)#
Step 9
	address-family {ipv4 tunnel}	Configures IPv4 tunnel address family.
	Example:
	RP/0/RP0/CPU0:router(config-bgp-nbr-af)#
	address-family ipv4 tunnel
Step 10
	vrf vrf-name	Configures a VRF instance.
	Example:
	RP/0/RP0/CPU0:router(config-bgp-nbr-af)# vrf
	9999
	RP/0/RP0/CPU0:router(config-bgp-vrf)#
Step 11
	rd {as-number:nn ip-address:nn auto}	Configures a route distinguisher.
		Note	Use the auto keyword to automatically assign a
	Example:		unique route distinguisher.
	RP/0/RP0/CPU0:router(config-bgp-vrf)# rd auto
Step 12
	address-family {ipv4 unicast}	Configures IPv4 unicast address family.
	Example:
	RP/0/RP0/CPU0:router(config-bgp-vrf)#
	address-family ipv4 unicast
	RP/0/RP0/CPU0:router(config-bgp-vrf-af)#
