neighbor.

Usage
Keepalive messages are sent by a router to inform another router that the BGP
connection between the two is still active. The keepalive interval is the period of
time between each keepalive message sent by the router. The holdtime interval is
the time the router waits to receive a keepalive message and if it does not receive
Parameter

{
<ip-address>
|

|
<peer-group>
}
<ip-address>
Specify the address of an IPv4 BGP neighbor, in
dotted decimal notation A.B.C.D.
<ipv6-addr>
Specify the address of an IPv6 BGP4+ neighbor,
entered in hexadecimal in the format X:X::X:X.
<peer-group>
Enter the name of an existing peer-group. For
information on how to create peer groups, refer
