The type of route. The value 'other' is not supported,
and is included only for compatiblity with the IP
Forwarding Table MIB. The value 'local' indicates
that the destination is treated as if it were
directly connected. The value 'remote' indicates that
the forwarding address will be used to reach the
destination. The value 'reject' indicates that if
this route is matched, a packet to the destination is
discarded and a notification (e.g. ICMP error) is
returned to the packet sender. The value
'blackhole' indicates that if the route is matched,
a packet to the destination is silently dropped.
The value of this object must be consistent with
the forwarding address information used to index
the route.
