Chapter Cisco MWR 2941 Router Command Reference, Release 15.1(3)MR
neighbor remote-as (BGP)
Usage Guidelines Specifying a neighbor with an autonomous system number that matches the autonomous system number
specified in the router /jointfilesconvert/475093/bgp global configuration command identifies the neighbor as internal to the local
autonomous system. Otherwise, the neighbor is considered external.
If you specify a BGP peer group by using the peer-group-name argument, all the members of the peer
group will inherit the characteristic configured with this command.
By default, neighbors that are defined using the neighbor remote-as command in router configuration
mode exchange only unicast address prefixes. To exchange other address prefix types, such as multicast
and Virtual Private Network (VPN) Version 4, neighbors must also be activated in the appropriate
address family configuration mode.
To ensure a smooth transition, we recommend that all BGP speakers within an autonomous system that
is identified using a 4-byte autonomous system number, be upgraded to support 4-byte autonomous
system numbers.
Examples The following example specifies that a router at the address 10.108.1.2 is an internal BGP (iBGP)
neighbor in autonomous system number 65200:
router /jointfilesconvert/475093/bgp 65200
network 10.108.0.0
neighbor 10.108.1.2 remote-as 65200
The following example assigns a BGP router to autonomous system 65400, and two networks are listed
as originating in the autonomous system. Then the addresses of three remote routers (and their
autonomous systems) are listed. The router being configured will share information about networks
10.108.0.0 and 192.168.7.0 with the neighbor routers. The first router is a remote router in a different
autonomous system from the router on which this configuration is entered (an eBGP neighbor); the
second neighbor remote-as command shows an internal BGP neighbor (with the same autonomous
