A regular expression, otherwise known as regexp, are symbols derived from programming languages that allow you to filter prefixes in BGP advertisements based on Autonomous System paths.

The regular expressions search strings of text for specific target characters. In BGP, they are used to configure as-path access lists.


ip as-path access-list 10 permit ^$

Not sure what you mean.

You want information on how to configure a Cisco device to send system information to a syslog server? Or are you looking for information on how to configure the server itself?
