BGP Route-Map Logic

ArtiomL

Hi,

Just wanted to share a drawing I made explaining BGP Route-Map Logic:

I would love to hear your comments / suggestions.

Thanks!

I would explicitly say "do action_X and pass the route along".  I know it's reasonable to imply that, but it makes it clearer that the route does get passed, whereas the deny clauses don't pass the route along.

It's also beneficial when you take your route maps to the next level with the 'continue' clause.  With it, you can "match, set, and jump forward", rather than "match, set, send the route and exit".  I use this in great detail to set local pref, communities, and MED sequentially rather than having to do a full matrix of match conditions.

Thanks Peety!

Awesome comments / suggestions!

I will fix the drawing and repost it later.

Any other issues / inaccuracies?

 

Thanks!

Well done ArtiomL!  I like it.

well scripted at the side which will help understand the actual logic of route map.
But as said by Peety, actions can further extended to next level .

 

cheers....

Great work.   Wish I had this when I first started learning route-maps.  [:^)]
