how does it work in order if bgp conditional advertisement and route-map

Hi,

 

I need some more clarification when we use bgp conditional advertisement and route-map both for the particular neighbor. see the below.

ex)

router bgp 1

 neighbor xxx.xxx.xxx.xxx route-map route-map-out-a out
 neighbor xxx.xxx.xxx.xxx advertise-map aaa exist-map bbb

If configuration likes above, I thought either we have both, the route-map can be worked to send the routes to neighbor at final stage. am I right?

Even though advertise-map work if exist-map matched up, the route-map set to deny out for all routes, then, it won't update nothing to neighbor xxx?

 

Thanks.

Hi,

 

Router will not advertise the route that is denied under the route-map.

route-map: match all routes in rib

advertise-map: match only bgp route in rib

Hope this helps.
