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.
