StaticIPLookup(ADDR1/MASK1 [GW1] OUT1, ADDR2/MASK2 [GW2] OUT2, ...)

=s IP, classification

simple static IP routing table

=d

B<Note:> Lookups and table updates with StaticIPLookup are extremely slow; the
RadixIPLookup, DirectIPLookup, and RangeIPLookup elements should be preferred
in almost all cases.  See IPRouteTable for a performance comparison.  We
provide StaticIPLookup nevertheless for its simplicity.

This element acts like LinearIPLookup, but does not allow dynamic adding and
deleting of routes.

=h table read-only

Outputs a human-readable version of the current routing table.

=h lookup read-only

Reports the OUTput port and GW corresponding to an address.
