Juniper BGP - CONFIGURATION GUIDE V 11.1.X

■ Use to associate a textual description of up to 80 characters with a BGP neighbor
or peer group.
■ If you specify a BGP peer group by using the peerGroupName argument, all the
members of the peer group inherit the characteristic configured with this
command unless it is overridden for a specific peer.
■ This command takes effect immediately.
■ Example
host1(config-router)#neighbor 10.11.0.5 description bostonmetropeer
■ Use the no version to remove the description.
■ See neighbor description
Logging Neighbor State Changes
You can force BGP to log a message whenever a peer enters or leaves the Established
state.
bgp log-neighbor-changes
■ Use to log a notice message to the bgpNeighborChanges log when a neighbor
enters or leaves the Established state for any reason.
■ The severity of the log message is notice by default.
■ Issue the log destination console severity notice command to display the
messages on the console.
■ This command takes effect immediately.
■ Example
host1:3(config)#bgp log destination console severity notice
host1:3(config)#router bgp 100
host1:3(config-router)#bgp log-neighbor-changes
