The ebgp-value, ibgp-value and local-value parameters are in the range of 1 to 256. By
default, the first two is 256 and the last one is 130.
6.2.11 Configuring BGP Timer
When receiving an OPEN message to set up a BGP connection, a BGP speaker needs
to calculate a hold timer. The smaller between its own Hold time and the one received in
the message will be selected as the negotiated Hold Timer. Then, BGP will send a
KeepAlive message and set a KeepAlive timer. If the negotiation result is 0, no
keepalive Message will be transmitted and whether the hold-time has timed out will not
be cared.
Perform the following configurations in BGP view.

By default, the interval of sending keepalive packet is 60 seconds. The interval of
sending holdtime packet is 180 seconds.
6.2.12 Configuring the local preference
Different local preferences can be configured to affect the BGP routing. When a router
running BGP gets routes with the same destination address but different next hops
through different internal peers, it will select the route of the highest local preference.
Perform the following configurations in BGP view.
