In order to help understand the characteristics of a peer, you can configure 
description for a peer (group).

■

By default, no BGP peer (group) description is set.

Generally, EBGP peers must be connected physically, or the command below can 
be used to perform the configuration.

By default, it is only permitted to create connections with peer groups on directly 
connected networks. ttl represents the maximum hop count, ranging from 1 to 
255. By default, it is 64.

The 

 command is used to configure the timer of a specified BGP peer 

(group), including the keep-alive message interval and the hold timer. The 
preference of this command is higher than the 

 command that is used to 

configure timers for all the BGP peers.

By default, the keep-alive message is sent every 60 seconds and the value of the 
hold timer is 180 seconds.

Table 635   Configuring timer of a peer (group)

Configure keep-alive interval and hold 
timer of a specified peer (group)

peer { group-name | peer-address } 
timer keep-alive keepalive-interval

Restore the default keep-alive interval 
and hold timer of a specified peer 
(group)
