Implementing MPLS Layer 3 VPNs
Places the router in neighbor configuration mode for BGP routing and configures the neighbor IP address .40.25.2 as an
VPNv4 iBGP peer.
Step 11
remote-as autonomous-system-number
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# remote-as 2002
Creates a neighbor and assigns it a remote autonomous system number.
Step 12
update-source type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# update-source loopback0
Allows BGP sessions to use the primary IP address from a particular interface as the local address.
Step 13
address-family ipv4 labeled-unicast
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# address-family ipv4 labeled-unicast
RP/0/RP0/CPU0:router(config-bgp-nbr-af)#
Enters neighbor address family configuration mode for the IPv4 labeled-unicast address family.
Step 14
route-reflector-client
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# route-reflector-client
Configures the neighbor as a route reflector client.
Step 15
Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
