Chapter37 IPv6 over MPLS: 6PE and 6VPE
How to Configure IPv6 over MPLS: 6PE and 6VPE
Step 8
no bgp default ipv4-unicast
Example:
Router(config-router)# no bgp default
ipv4-unicast
Disables the default IPv4 unicast address family for peering session
establishment.
Step 9
neighbor {
ip-address
|
ipv6-address
|
peer-group-name
} remote-as
as-number
Example:
Router(config-router)# neighbor
10.108.1.2 remote-as 65200
Adds an entry to the BGP or multiprotocol BGP neighbor table.
• ip-address—IP address of a peer router with which routing
information will be exchanged.
• ipv6-address—IPv6 address of a peer router with which routing
information will be exchanged.
• 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 |
peer-group-name} update-source
interface-type interface-number
Example:
Router(config-router)# neighbor
172.16.2.3 update-source Loopback0
Configures BGP sessions to use any operational interface for TCP
connections.
Step 11
address-family ipv6
Example:
Router(config-router)# address-family
ipv6
Enters address family configuration mode for configuring routing
sessions, such as BGP, that use standard IPv6 address prefixes.
Step 12
neighbor {
ip-address
|
ipv6-address
|
peer-group-name
} activate
Example:
Router(config-router-af)# neighbor
10.0.0.44 activate
Enables the exchange of information with a BGP neighbor.
Step 13
neighbor {
ip-address
|
ipv6-address
|
peer-group-name
} send-label
Example:
Router(config-router-af)# neighbor
10.0.0.44 send-label
Sends MPLS labels with BGP routes to a neighboring BGP router.
Step 14
exit-address-family
Example:
Router(config-router-af)#
exit-address-family
Exits BGP address-family submode.
