I want to have a prefix list that will permit a /16 address block as well as any networks within the /16. In other words the network could have networks
instead of allowing the individual networks I wanted to all the whole /16 in one line in the prefix list
Can i do this using the ge command ?
ip prefix-list XXX permit 172.20.0.0/16 ge ?
I tried to do " ge 16" and got a message saying "% Invalid prefix range for 172.20.0.0/16, make sure: len < ge-value <= le-value"
If you want to include 172.16.0.0/16 and any subnets of that then you should use -
172.16.0.0/16 le 32
which means the first 2 octets must match 172.16. and then you can have combination of subnet mask after that ie. 17, 18, 19 -> 32.
