> ip extcommunity-list 100 permit 3549:4[0-9]* > ip extcommunity-list 100 permit 3549:4.* Unless you are trying to match extended community attribute, I don't think you should be using "extcommunity-list", but "community-list". The following should do the trick: ip community-list 100 permit 3549:4[0-9]* Marko.
