Hello,I have been recently placed in the awkward position of making some changes to our BGP configuration. The problem is that I understand how bgp works for the main part, but I don't have any information on the meaning of the symbols used in the following as-path access-lists (^, $, _, ., +, (), *). Could someone tell me what each of them mean? Could someone also point me to a Cisco page that explains them in detail? I have been searching and cannot find anything except examples that include these symbols. Unfortuneately these examples have not helped my understanding. I have a good idea as to what they probably mean, but I need to know their exact meaning. It is difficult to manage something you don't have a clear understanding of!
ip as-path access-list 1 permit ^$
ip as-path access-list 4 permit ^(_6774) +$
ip as-path access-list 10 permit .*5413$
ip as-path access-list 6 permit ^ (_3414) + (_2423) +$HELP!!!
