Configuring IP Unicast Routing
Configuring BGP
DETAILED STEPS
Command Purpose
1. configure terminal Enter global configuration mode.
2. router bgp autonomous-system Enter BGP router configuration mode.
3. neighbor peer-group-name peer-group Create a BGP peer group.
4. neighbor ip-address peer-group
peer-group-name
Make a BGP neighbor a member of the peer group.
5. neighbor {ip-address | peer-group-name}
remote-as number
Specify a BGP neighbor. If a peer group is not configured
with a remote-as number, use this command to create
peer groups containing EBGP neighbors. The range is 1
to 65535.
6. neighbor {ip-address | peer-group-name}
description text
(Optional) Associate a description with a neighbor.
7. neighbor {ip-address | peer-group-name}
default-originate [route-map map-name]
(Optional) Allow a BGP speaker (the local router) to send
the default route 0.0.0.0 to a neighbor for use as a
default route.
8. neighbor {ip-address | peer-group-name}
send-community
(Optional) Specify that the COMMUNITIES attribute be
sent to the neighbor at this IP address.
9. neighbor {ip-address | peer-group-name}
update-source interface
(Optional) Allow internal BGP sessions to use any
operational interface for TCP connections.
10. neighbor {ip-address | peer-group-name}
ebgp-multihop
(Optional) Allow BGP sessions, even when the neighbor
is not on a directly connected segment. The multihop
session is not established if the only route to the
multihop peer’s address is the default route (0.0.0.0).
11. neighbor {ip-address | peer-group-name}
local-as number
(Optional) Specify an AS number to use as the local AS.
The range is 1 to 65535.
12. neighbor {ip-address | peer-group-name}
advertisement-interval seconds
(Optional) Set the minimum interval between sending
BGP routing updates.
13. neighbor {ip-address | peer-group-name}
maximum-prefix maximum [threshold]
(Optional) Control how many prefixes can be received
from a neighbor. The range is 1 to 4294967295. The
threshold (optional) is the percentage of maximum at
which a warning message is generated. The default is
75 percent.
14. neighbor {ip-address | peer-group-name}
next-hop-self
(Optional) Disable next-hop processing on the BGP
updates to a neighbor.
15. neighbor {ip-address | peer-group-name}
password string
(Optional) Set MD5 authentication on a TCP connection
to a BGP peer. The same password must be configured
on both BGP peers, or the connection between them is
not made.
16. neighbor {ip-address | peer-group-name}
route-map map-name {in | out}
(Optional) Apply a route map to incoming or outgoing
routes.
17. neighbor {ip-address | peer-group-name}
send-community
(Optional) Specify that the COMMUNITIES attribute be
sent to the neighbor at this IP address.
