Hello all,
I'm wondering if it is possible to multiple "in-filter" on a BGP peer ?
I'd like to have a global filter for all my peers (filtering RFC1918 for instance) and more specific filter for each peer (setting local-pref or filtering prefixes from IRR).
Maintaining a load of routing filters when changing a parameter which is applicable for every peer is a pain :/
Thank you in advance.

Re: Multiple BGP in-filters
this is possible. I would recoment to make a script, setting filter for your bgp... eg..
Code: Select all
if "as nr" bla bla bla set routing filter bla bla bla [as nr]
possible to do somethig like:
"read peer as nr.. parse something to filter from this"

Thank you for the answer. I'm not sure I understand everything but it's still a pointer.

Re: Multiple BGP in-filters
Well. answer is. yes. its possible to do it and have more than one "chain". 
mark connection. packet or something. Make rulset based on AS nr.. Make one global, and one unit spesific. (unit spesific can be global made, by a script like the one i "wrote about" if based on AS nr.)
