Access list vs prefix list
I came across a sentence in bgp that in bgp access list are used for traffic filtering
and prefix list is used for route filtering . Is this statement correct? If we refer to below
two commands:
access-list 10 deny 10.1.0.0 0.0.255.255
ip prefix-list prefiz deny 10.1.0.0/16
these two commands are doing the same things so why use prefix list for route filtering
we can use access list for filtering
Also there is one more statement that if we have same prefix but different subnet
mask access list falls apart and we need to use prefix list
eg: We have two routes coming from same neighbor
28.119.16.0/24 and 28.119.16.0/23
In this case it is recommended to use prefix list but if i use access list (access-list I
28.119.16.0 0.o.l.o)
should it not filter out the 123 route and keep 124 route
