i have matched some bgp routes with prefix-list and set local higher local pref for some destination prefixes but same i am getting output when i am matching same routes with standard access-list then why should i use confusing or complex prefix-list? what the exact use of it? and when?
thanks and regards,
Lets take an example :
You need to permit 150.5.x.x network an only which has a default class B subnet mask and allow on the routes which have grtaer than 28 bit mask.
ip prefix-list abc permit 22.214.171.124/16 ge 28
With prefix-list above only the masks which are greater than 28 will be selected.
You wont be able to match it with an ACL.
