2. Add a neighbor as a remote AS.

CONFIG-ROUTER-BGP mode

neighbor {ip-address | peer-group name} remote-as as-number

• peer-group name: 16 characters

• as-number: from 0 to 65535 (2 Byte) or from 1 to 4294967295 (4 Byte) or 0.1 to 65535.65535 (Dotted format)

Formats: IP Address A.B.C.D

You must use Conguring Peer Groups before assigning them a remote AS.

3. Enable the BGP neighbor.

CONFIG-ROUTER-BGP mode

neighbor {ip-address | peer-group-name} no shutdown

Example of the show ip bgp summary Command (2-Byte AS number displayed)

Example of the show ip bgp summary Command (4-Byte AS number displayed)

Example of the show ip bgp neighbors Command

Example of Verifying BGP Conguration

NOTE: When you change the conguration of a BGP neighbor, always reset it by entering the clear ip bgp command

in EXEC Privilege mode.

To view the BGP conguration, enter show config in CONFIGURATION ROUTER BGP mode. To view the BGP status, use the

show ip bgp summary command in EXEC Privilege mode. The rst example shows the summary with a 2-byte AS number

displayed (in bold); the second example shows that the summary with a 4-byte AS number using the show ip bgp summary

command (displays a 4–byte AS number in bold).
