Chapter 37 IPv6 over MPLS: 6PE and 6VPE

How to Configure IPv6 over MPLS: 6PE and 6VPE

	Command		Purpose
Step 8	no bgp default ipv4-unicast		Disables the default IPv4 unicast address family for peering session
			establishment.
	Example:
	Router(config-router)# no bgp default
	ipv4-unicast
Step 9	neighbor {ip-address ipv6-address		Adds an entry to the BGP or multiprotocol BGP neighbor table.
	peer-group-name}remote-asas-number		• ip-address—IP address of a peer router with which routing
	Example:		information will be exchanged.
			• ipv6-address—IPv6 address of a peer router with which routing
	Router(config-router)# neighbor
			information will be exchanged.
	10.108.1.2 remote-as 65200
			• peer-group-name—Name of the BGP peer group.
			• remote-as—Specifies a remote autonomous system.
			• as-number—Number of an autonomous system to which the
			neighbor belongs, ranging from 1 to 65535.
Step 10	neighbor {ip-address ipv6-address		Configures BGP sessions to use any operational interface for TCP
	peer-group-name} update-source		connections.
	interface-type interface-number
	Example:
	Router(config-router)# neighbor
	172.16.2.3 update-source Loopback0
Step 11	address-family ipv6		Enters address family configuration mode for configuring routing
			sessions, such as BGP, that use standard IPv6 address prefixes.
	Example:
	Router(config-router)# address-family
	ipv6
Step 12	neighbor {ip-address ipv6-address		Enables the exchange of information with a BGP neighbor.
	peer-group-name}activate
	Example:
	Router(config-router-af)# neighbor
	10.0.0.44 activate
Step 13	neighbor {ip-address ipv6-address		Sends MPLS labels with BGP routes to a neighboring BGP router.
	peer-group-name}send-label
	Example:
	Router(config-router-af)# neighbor
	10.0.0.44 send-label
Step 14	exit-address-family		Exits BGP address-family submode.
	Example:
	Router(config-router-af)#
	exit-address-family
