BGP policy routing (community string)

Hello,

I'm trying to setup routing where I automatically modify the community string attribute of a prefix based on the one of the following:

Link changes between other peer

Adjacency state of another peer

Route's next hop address.

My main goal is to if one peer goes down I would like to change the community string attribute of my advertised prefix to my second peer.

I'm trying to see if route-map will be able to do that, does anyone have any ideas how i could do this?

Thanks in advance for you help.

Re: BGP policy routing (community string)

There has been a featurette request for this for years, but there's never been any real push to get it coded and running. At this point, I don't know of any way to do this, unless you can do some clever tricks with conditional advertisement.
