Zebra provides many very flexible filtering features. Filtering is used for both input and output of the routing information. Once filtering is defined, it can be applied in any direction.

Basic filtering is done by `access-list' as shown in the following
example.
Command: access-list NAME deny IPV4-NETWORK
access-list filter deny 10.0.0.0/9
access-list filter permit 10.0.0.0/8
