Thank you very much for the help. Gated has been driving me crazy, and I do not like the gated.conf examples (and lack thereof) on any of the sites I've looked have helped me more than the people I've talked with about it in the last two days. Thanks, Joe Shaw - jshaw () insync net NetAdmin - Insync Internet Services #!/usr/bin/perl # Standard Disclaimer to keep Joe from getting in trouble again. print (" ***Disclaimer***\n"); print (" The opinions of Joe Shaw are not necessarily those of Insync\n"); print (" Internet Services or of any of it's other employees.

Although not exactly what I needed to know at the time, it did teach me a lot about what I was trying to do, and the rest came a little easier. One problem I'm having, is I've got several regular expression statemenst I'm trying to use to filter my routes to one of my upstream carriers. I had a t1 to this upstream to test out how much we liked their network, and now we're moving up to oc-3 to them. What we've done is purchased a GRF for this link, and run the ATM into it. I'd like to duplicate the as-path access-list for the oc-3. The Cisco config follows. ip as-path access-list 31 deny _3831_ ip as-path access-list 31 deny _701_ ip as-path access-list 31 deny _114_ ip as-path access-list 31 deny _6302_ ip as-path access-list 31 deny ^4259 .* ip as-path access-list 31 deny ^3817 .* ip as-path access-list 31 permit .* These do the job on my network, and I'm happy with them. On the GRF, I've done this to try and duplicate them:OK Change this to: export proto bgp as 3831 { proto bgp aspath .* origin any { all; }; proto bgp aspath 3831 origin any restrict; proto bgp aspath 701 origin any restrict; proto bgp aspath 6302 origin any restrict; proto bgp aspath 4259 * origin any restrict; proto bgp aspath 3817 * origin any restrict; } I think this is correct, but if it isn't working I'd move the the top clause to the bottom and put the others above [order is important, but the order isn't _yet_ documented] You should have a look at filter declations such as this below: define filter "AS-3831" { proto bgp aspath .* origin any { all; }; proto bgp aspath 3831 origin any restrict; proto bgp aspath 701 origin any restrict; proto bgp aspath 6302 origin any restrict; proto bgp aspath 4259 * origin any restrict; proto bgp aspath 3817 * origin any restrict; }; Then do: export proto bgp as 6453 "AS-3831"; Note that I've not tried doing the above, but it should work, it means you can %include filters and makes your gated.conf files much easier to read.
