DETAILED STEPS
Configuring AS-path Lists
You can specify an AS-path list filter on both inbound and outbound BGP routes. Each filter is an access
list based on regular expressions. If the regular expression matches the representation of the AS-path
attribute of the route as an ASCII string, then the permit or deny condition applies.
SUMMARY STEPS
1. configure terminal
2. ip as-path access-list name {deny | permit} expression
3. (Optional) show ip as-path list name
4. (Optional) copy running-config startup-config
Command Purpose
Step 1
configure terminal
Example:
switch# configure terminal
switch(config)#

switch(config)# mac-list AllowMac seq 1

the MAC address to match against and is in MAC
