If the router has established a neighbor relationship with a peer, you must reset the BGP connection
•
to validate the new set timers.
The timer command takes effect for only new connections.
•
After peer timer command is executed, the peer connection is closed at once, and a new
•
connection to the peer is negotiated using the configured hold time.
To configure BGP keepalive interval and holdtime:
Step
1.
Enter system view.
2.
Enter BGP view.
3.
Configure BGP keepalive interval
and holdtime.
Configuring the interval for sending the same update
Step
1.
Enter system view.
2.
Enter BGP view.
3.
Configure the interval for sending the
same update to a peer or peer group.
Configuring BGP soft-reset
After modifying the route selection policy, reset BGP connections to make the new one take effect.
The current BGP implementation supports the route-refresh feature that enables dynamic route refresh
without tearing down BGP connections.
However, if a peer not supporting route-refresh exists in the network, you must configure the peer
keep-all-routes command to save all routes from the peer, which are used during applying the new route
selection policy.
