Purpose
(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.
(Optional) Set timers for the neighbor or peer group.
The keepalive interval is the time within which keepalive
•
messages are sent to peers. The range is 1 to 4294967295
seconds; the default is 60.
The holdtime is the interval after which a peer is declared
•
inactive after not receiving a keepalive message from it. The
range is 1 to 4294967295 seconds; the default is 180.
(Optional) Specify a weight for all routes from a neighbor.
(Optional) Filter BGP routing updates to or from neighbors, as
specified in an access list.
(Optional) Establish a BGP filter.
(Optional) Specify the BGP version to use when communicating
with a neighbor.
(Optional) Configure the software to start storing received
updates.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
