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:
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:
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>}
default-originate [route-map
<routemap-name>]
This command allows the redistribution of the default network
0.0.0.0 into BGP from the Router Configuration mode.
awplus(config-router-af)#
neighbor {<neighborid>}
default-originate [route-map
<routemap-name>]
This command allows the redistribution of the default network
0.0.0.0 into BGP from the Address Family Configuration mode.
awplus(config-router)#
timers bgp <keepalive>
<holdtime>
This command adjusts BGP timers for all neighbors.
awplus(config-router)#
neighbor <neighborid> timers
{<keepalive> <holdtime>|connect
<connect>}
This command sets the keepalive and hold-time timers (in
seconds) for the specified peer or peer group. To clear the
timers for a BGP neighbor or peer group, use the negated form
of the neighbor timers command.
