BGP and BGP4+ Introduction

How to redistribute the default network 0.0.0.0

By default, you are not allowed to redistribute network 0.0.0.0. To permit the redistribution of network 0.0.0.0, use the following command in Router Configuration or Address Family Configuration modes:

awplus(config-router)#

neighbor {<neighborid>} This command allows the redistribution of the default network default-originate[route-map0.0.0.0 into BGP from the Router Configuration mode.

<routemap-name>]

awplus(config-router-af)#

neighbor {<neighborid>} This command allows the redistribution of the default network default-originate[route-map0.0.0.0 into BGP from the Address Family Configuration mode.

<routemap-name>]

How to adjust BGP Timers

BGP uses certain timers to control periodic activities such as the sending of keepalive messages and the interval after not receiving a keepalive message after which software declares a peer dead.

By default, the keepalive timer is 60 seconds, and the hold-time timer is 180 seconds.You can adjust these timers. When a connection is started, BGP will negotiate the hold time with the neighbor. The smaller of the two hold times will be chosen. The keepalive timer is then set based on the negotiated hold time and the configured keepalive time.

To adjust BGP timers for all neighbors, use the following command in Router

Configuration mode:

awplus(config-router)#

timers bgp <keepalive> This command adjusts BGP timers for all neighbors.

<holdtime>

To adjust BGP keepalive and hold-time timers for a specific neighbor, use the following command in Router Configuration mode:

awplus(config-router)#

neighbor <neighborid> timers This command sets the keepalive and hold-time timers (in {<keepalive> <holdtime>connect seconds) for the specified peer or peer group. To clear the

<connect>} timers for a BGP neighbor or peer group, use the negated form of the neighbor timers command.
