Implementing MPLS Layer 3 VPNs
Example:
RP/0/RP0/CPU0:router(config-bgp-af)# neighbor 172.168.40.24
RP/0/RP0/CPU0:router(config-bgp-nbr)#
Places the router in neighbor configuration mode for BGP routing and configures the neighbor IP address 172.168.40.24
as a BGP peer.
Step 6
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 7
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 8
route-policy route-policy-name in
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# route-policy pass-all in
Applies a routing policy to updates that are received from a BGP neighbor.
• Use the route-policy-name argument to define the name of the of route policy. The example shows that the route
policy name is defined as pass-all.
• Use the in keyword to define the policy for inbound routes.
Step 9
route-policy route-policy-name out
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# route-policy pass-all out
Applies a routing policy to updates that are sent to a BGP neighbor.
• Use the route-policy-name argument to define the name of the of route policy. The example shows that the route
policy name is defined as pass-all.
• Use the out keyword to define the policy for outbound routes.
Step 10
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:
