Configuring Mpls Forwarding For Asbr Confederations - Cisco CRS Configuration Manual

Providing VPN Connectivity Across Multiple Autonomous Systems with MPLS VPN Inter-AS with ASBRs Exchanging
VPN-IPv4 Addresses
Creates a neighbor and assigns it a remote autonomous system number.
Step 8 address-family vpnv4 unicast
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# address-family vpnv4 unicast
RP/0/RP0/CPU0:router(config-bgp-nbr-af)#
Configures VPNv4 address family.
Step 9 route-policy route-policy-name in
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# route-policy In-Ipv4 in
Applies a routing policy to updates received from a BGP neighbor.
Step 10 route-policy route-policy-name out
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# route-policy Out-Ipv4 out
Applies a routing policy to updates advertised to a BGP neighbor.
Step 11 next-hop-self
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# next-hop-self
Disables next-hop calculation and let you insert your own address in the next-hop field of BGP updates.
Step 12 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.
