  • show bgp ipv4 unicast regex $300
  • show bgp ipv4 unicast regex .300.
  • show bgp ipv4 unicast regex _300_
  • show bgp ipv4 unicast regex ^300_

Explanation: In troubleshooting BGP, Regular expressions (regex) can be used to parse through the large number of available ASNs. Regular expressions are based on query modifiers used to select the appropriate content. The regex pattern ^300_ indicates to only include the lines that list the exact phrase of 300 as the first AS. Some regex query modifiers are as follows:
_ (underscore) – matches a space
^ (caret) – indicates the start of a string
$ (dollar sign) – indicates the end of a string
. (period) – matches a single character, including a space
