Routing Table
Routing Table Overview
Routing is based on the destination address only and the Zyxel Device takes the shortest path to forward a packet.
Routing Table
The table below shows IPv4 and IPv6 routing information. The IPv4 subnet mask is ‘255.255.255.255’ for a host destination and ‘0.0.0.0’ for the default route. The gateway address is written as ‘*’(IPv4)/‘::’(IPv6) if none is set.
