Table 6-22 Configure a route filtering policy based on address prefixes
Configure
prefixes-based route filtering policy to
routes received from a peer/peer group
Cancel the address prefixes-based route
filtering policy applied to routes received
from a peer/peer group
Configure
prefixes-based route filtering policy to
routes advertised to a peer group
Cancel the address prefixes-based route

By default, no route filtering policy based on address prefixes is applied to routes
advertised or received.

6.2.6 Configuring BGP Timers

After a BGP connection is established between peers, each peer periodically sends
Keepalive message to the other so as to avoid the routers from assuming that the BGP
connection is down. If a router does not receive any Keepalive message or any kind of
packet from the peer within the specified Holdtime, it assumes that the BGP connection
is down and processes the routes received from the BGP connection accordingly.
Therefore, the interval for sending a Keepalive message and the BGP connection
Holdtime are two important parameters in BGP mechanism.
When a BGP router tries to establish a BGP connection with its peer, a negotiation
needs to be carried out on the Holdtime. The resulting Holdtime is the smaller one
those for the peers. If the resulting Holdtime is 0, no keepalive message will be
transmitted and no detection on whether the Holdtime is timed out will be performed.
