Filter lists can be used to allow or deny certain prefixes during redistribution by the BGP. LISP and OSPF. To do this, create the prefix filter list under .
- Name
- Give this entry a name here. Prefixes that should belong to a list are referenced by the same name, e.g. List1.
- IP address
- Specify the IPv4 or IPv6 address of the network here.
- Prefix length
- Contains the netmask or prefix length of the network. This entry specifies how many most-significant bits (MSB) of the prefix must match to the IP address. The prefix length must exactly match this value unless Min. prefix length and Max. prefix length are set to values not equal to zero. If the value is "0", the prefix for this rule is a match if it comes from same IP address family as that specified under IP address.
- Min. prefix length
- Here you specify the minimum prefix length value required for the prefix to match.
- Max. prefix length
- Here you specify the maximum prefix length value required for the prefix to match.

Using prefix lists with BGP
These prefix lists can be referenced for the IPv4 and IPv6 address families of the BGP protocol, and you can specify whether these prefix lists should be allowed or rejected
Using prefix lists with LISP
These Prefix lists can be used to allow or deny certain prefixes during route redistribution by LISP. Use the prefixes defined here for redistributing static routes, BGP, OSPF and connected routes.
Using prefix lists with OSPF
These Prefix lists can be used to allow or deny certain prefixes during route redistribution by OSPF. Use the prefixes defined here for redistributing static routes, BGP and connected routes.
