Disabling and Reenabling Dynamic Policy Configuration
By default, BGP reconfigures IP policies dynamically. This means that if you
modify a policy, BGP dynamically reevaluates all affected routes in the light of
the modified policy. BGP then sends the appropriate withdraw or update to the
affected peers. BGP maintains records of which routes have been sent to which
peer, allowing for precise determination of which routes must be sent and which
must be withdrawn.
If you modify an IP policy with this feature disabled, BGP restarts all BGP
connections. There is no advantage to disabling dynamic policy configuration.
Disabling this parameter will significantly impact BGP protocol operation
overhead and network stability.
You can use the following Site Manager procedure to disable and reenable
dynamic policy configuration:
