Purpose
Enter global configuration mode.
Enter BGP router configuration mode.
Create a BGP peer group.
Make a BGP neighbor a member of the peer group.
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.
(Optional) Associate a description with a neighbor.
(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.
(Optional) Specify that the COMMUNITIES attribute be
sent to the neighbor at this IP address.
(Optional) Allow internal BGP sessions to use any
operational interface for TCP connections.
(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).
(Optional) Specify an AS number to use as the local AS.
The range is 1 to 65535.
(Optional) Set the minimum interval between sending
BGP routing updates.
(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.
(Optional) Disable next-hop processing on the BGP
updates to a neighbor.
(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.
(Optional) Apply a route map to incoming or outgoing
routes.
(Optional) Specify that the COMMUNITIES attribute be
sent to the neighbor at this IP address.
