By default, no BGP peer group description is set.
Configuring to Permit Connections with EBGP Peer Groups on Indirectly
Connected Networks
Generally, EBGP peers must be connected physically.
Otherwise the command below can be used to perform the configuration to make
them communicate with each other normally.
By default, only the connections with EBGP peers (groups) on directly connected
networks are permitted. ttl refers to time-to-live in the range of 1 to 255 with the
default value as 64.
Configuring the Peer Group Timer The peer timer command is used to
configure timers of the BGP peer group, including the keep-alive message interval
and the hold timer. The preference of this command is higher than the timer
command that is used to configure timers for the whole BGP peers.
By default, the keep-alive message is sent every 60 seconds and the value of the
hold timer is 180 seconds.
