BGP Conditional Advertisement
|
||||||
|
-----------------------------
|
||||||
|
The BGP conditional advertisement feature uses the ``non-exist-map`` or the
|
||||||
|
``exist-map`` and the ``advertise-map`` keywords of the neighbor advertise-map
|
||||||
|
command in order to track routes by the route prefix.
|
||||||
|
|
||||||
|
``non-exist-map``
|
||||||
|
1. If a route prefix is not present in the output of non-exist-map command,
|
||||||
|
then advertise the route specified by the advertise-map command.
|
||||||
|
|
||||||
|
2. If a route prefix is present in the output of non-exist-map command,
|
||||||
|
then do not advertise the route specified by the addvertise-map command.
|
||||||
|
|
||||||
|
``exist-map``
|
||||||
|
1. If a route prefix is present in the output of exist-map command,
|
||||||
|
then advertise the route specified by the advertise-map command.
|
||||||
|
|
||||||
|
2. If a route prefix is not present in the output of exist-map command,
|
||||||
|
then do not advertise the route specified by the advertise-map command.
|
||||||
|
|
||||||
|
This feature is useful when some prefixes are advertised to one of its peers
|
||||||
|
only if the information from the other peer is not present (due to failure in
|
||||||
|
peering session or partial reachability etc).
|
||||||
|
|
||||||
|
The conditional BGP announcements are sent in addition to the normal
|
||||||
|
announcements that a BGP router sends to its peer.
|
||||||
|
|
||||||
|
The conditional advertisement process is triggered by the BGP scanner process,
|
||||||
|
which runs every 60 seconds. This means that the maximum time for the conditional
|
||||||
|
advertisement to take effect is 60 seconds. The conditional advertisement can take
|
||||||
|
effect depending on when the tracked route is removed from the BGP table and
|
||||||
|
when the next instance of the BGP scanner occurs.
|
||||||
|
|
||||||
|
.. index:: [no] neighbor A.B.C.D advertise-map NAME [exist-map|non-exist-map] NAME
|
||||||
|
.. clicmd:: [no] neighbor A.B.C.D advertise-map NAME [exist-map|non-exist-map] NAME
|
||||||
|
|
||||||
|
This command enables BGP scanner process to monitor routes specified by
|
||||||
|
exist-map or non-exist-map command in BGP table and conditionally advertises
|
||||||
|
the routes specified by advertise-map command.
