6. Add a neighbor as a remote AS.
CONFIG-ROUTERBGP mode
neighbor {ip-address | peer-group name} remote-as as-number
Formats: IP Address A.B.C.D
• Peer-Group Name: 16 characters.
• as-number: the range is from 0 to 65535 (2-Byte) or 1 to 4294967295 | 0.1 to 65535.65535 (4-
Byte) or 0.1 to 65535.65535 (Dotted format)
To add an external BGP (EBGP) neighbor, configure the as-number parameter with a number
different from the BGP as-number configured in the router bgp as-number command.
To add an internal BGP (IBGP) neighbor, configure the as-number parameter with the same BGP as-
number configured in the router bgp as-number command.
Example of Viewing a Newly Created Peer Group
Example of Enabling a Peer Group
Example of the show ip bgp peer-group Command
After you create a peer group, you can use any of the commands beginning with the keyword neighbor
to configure that peer group.
When you add a peer to a peer group, it inherits all the peer group's configured parameters.
A neighbor cannot become part of a peer group if it has any of the following commands configured:
•
neighbor advertisement-interval
•
neighbor distribute-list out
•
neighbor filter-list out
•
neighbor next-hop-self
•
neighbor route-map out
•
neighbor route-reflector-client
•
neighbor send-community
A neighbor may keep its configuration after it was added to a peer group if the neighbor's configuration is
more specific than the peer group's and if the neighbor's configuration does not affect outgoing updates.
NOTE: When you configure a new set of BGP policies for a peer group, always reset the peer group
by entering the clear ip bgp peer-group peer-group-name command in EXEC Privilege
mode.
To view the configuration, use the show config command in CONFIGURATION ROUTER BGP mode.
When you create a peer group, it is disabled (shutdown). The following example shows the creation of a
peer group (zanzibar) (in bold).
