All, First, thank you for all who replied! I appreciate the help.
To summarize public and private responses, let me first point out there are likely several solutions to my problem. I am posting the one that I am most familiar with. nei Client_AS remote-as 18687 nei Client_AS version 4 nei Client_AS soft-reconfiguration inbound nei Client_AS password 7 $$$$$$ nei Client_AS filter-list 4 in nei Client_AS filter-list 4 out nei Client_AS advertise-map MAP1 non-exist-map MAP2 route-map MAP1 permit 10 match as-path 5 route-map MAP2 permit 20 match as-path 6 ip as-path access-list 4 permit ^$ ip as-path access-list 5 permit ^16631_ ip as-path access-list 6 permit ^701_ To answer the questions I had posted... A filter list command will take precedence over an advertise list. In this case the filter-list would have made a permit every time (.*) and never applied the advertise-map. I changed the filter-list out command to be my own AS. This will force the application of the advertise-map for other As-paths that are not originated by me. The route map can (of course) use as-paths instead of prefix's. Thank you Fabrice for the help on the correct regexp's! There may be more then one way to skin this cat but this falss closely to what I understand and it will work. thanks again, Jim Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=58535&t=58428 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
