Disabling Suppression of Route Advertisements

The JUNOS software does not advertise the routes learned from one external BGP (EBGP) peer back to the same EBGP peer. In addition, the software does not advertise those routes back to any EBGP peers that are in the same AS as the originating peer, regardless of the routing instance. You can modify this behavior by including the advertise-peer-as statement in the configuration. To disable the default advertisement suppression, including the advertise-peer-as statement:




advertise-peer-as;

Note: The route suppression default behavior is disabled if the as-override statement is included in the configuration.

If you include the advertise-peer-as statement in the configuration, BGP advertises the route regardless of this check.

To restore the default behavior, include the no-advertise-peer-as statement in the configuration:



no-advertise-peer-as;

If you include both the as-override and no-advertise-peer-as statements in the configuration, the no-advertise-peer-as statement is ignored. You can include these statements at multiple hierarchy levels.

For a list of hierarchy levels at which you can include these statements, see the statement summary section for this statement.
