Explanation

Martian addresses are host or network addresses about which all routing inf ormation is ignored. When received by the routing device, these routes are ignored. They commonly are sent by improperly configured systems on the network and have destination addresses that are obviously invalid. To view the default and configured martian routes, run the show route martians command.
