Filter

Routes learned from RIP can be filtered by their routing tag according to the settings for LAN and WAN RIP. Routes can additionally be filtered by specifying network addresses (e.g. "Only learn routes in the network 192.168.0.0/255.255.0.0"). First of all a central table is used to define the filters that can then be used by entries in the LAN and WAN RIP table.

Filters defined in the filter table can be referenced in the columns for RX filter and TX filter in the LAN RIP and WAN RIP tables. RX defines the networks from which routes can be learned or blocked, and TX defines the networks to which propagation should be allowed or blocked.
