Step 9
route-policy route-policy-name {out}
Example:
RP/0/0/CPU0:router(config-bgp-nbr-af)#
route-policy pass-all out
Applies a routing policy to updates that are sent 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 out keyword to define the policy for outbound
routes.
Step 10
neighbor ip-address
Example:
RP/0/0/CPU0:router(config-bgp-nbr-af)# neighbor
175.40.25.2
RP/0/0/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 11
remote-as autonomous-system-number
Example:
RP/0/0/CPU0:router(config-bgp-nbr)# remote-as
2002
Creates a neighbor and assigns it a remote autonomous
system number.
Step 12
update-source interface-type interface-number
Example:
RP/0/0/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 tunnel}
Example:
RP/0/0/CPU0:router(config-bgp-nbr)#
address-family ipv4 tunnel
RP/0/0/CPU0:router(config-bgp-nbr-af)#
Configures IPv4 tunnel address family.
