BGP Commands

Syntax [no] bgp
Context service>vprn

advertise-inactive
Syntax [no] advertise-inactive
Context config>service>vprn>bgp
config>service>vprn>bgp>group
config>service>vprn>bgp>group>neighbor
Description This command enables or disables the advertising of inactive BGP routers to other BGP peers.
By default, BGP only advertises BGP routes to other BGP peers if a given BGP route is chosen by the
route table manager as the most preferred route within the system and is active in the forwarding
plane. This command allows system administrators to advertise a BGP route even though it is not the
most preferred route within the system for a given destination.
Default no advertise-inactive
aggregator-id-zero
Syntax [no] aggregator-id-zero
Context config>service>vprn>bgp
config>service>vprn>bgp>group
config>service>vprn>bgp>group>neighbor
Description
This command is used to set the router ID in the BGP aggregator path attribute to zero when BGP
aggregates routes. This prevents different routers within an AS from creating aggregate routes that
contain different AS paths.
When BGP is aggregating routes, it adds the aggregator path attribute to the BGP update messages.
By default, BGP adds the AS number and router ID to the aggregator path attribute.
When this command is enabled, BGP adds the router ID to the aggregator path attribute. This
command is used at the group level to revert to the value defined under the global level, while this
command is used at the neighbor level to revert to the value defined under the group level.
