Delaying sending the BGP open message
Syntax:
[no] bgp open-on-accept
Delays sending the BGP Open message until an OPEN message is received. When
this command is specified, an OPEN message will be immediately sent when the
TCP connection has completed for configured peers. If the peer is not configured
(is matched by an allow clause, but not a peer command), it will continue to wait
for the OPEN message from the remote peer before sending its own BGP OPEN
message.
Specifying the maximum routes that BGP will accept for installation into the RIB
Syntax:
[no] bgp maximum-prefix max-routes
Specifies the maximum number of routes that BGP will accept for installation into
the Routing information Base (RIB). Use the noform of the command to set the
parameter to its default value.
