Configuring Inter-AS over IP Tunnels
• Use the route-policy-name argument to define the name of the 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 11
neighbor ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# neighbor 175.40.25.2
RP/0/RP0/CPU0:router(config-bgp-nbr)#
Places the router in neighbor configuration mode for BGP routing and configures the neighbor IP address 175.40.25.2
as an VPNv4 iBGP peer.
Step 12 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 13 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 14 address-family { ipv4 tunnel }
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# address-family ipv4 tunnel
RP/0/RP0/CPU0:router(config-bgp-nbr-af)#
Configures IPv4 tunnel address family.
Step 15
address-family { vpnv4 unicast }
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr-af)# address-family vpnv4 unicast
Configures VPNv4 address family.
Step 16 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.
