Hi , Could anyone help me to configure the folloing situation ? A physical interface of a router is multihomed with 172.17.4.0/24 and 172.17.5.0/24 nets . and the ip address of my host running linux is 172.17.4.60, how to confiure 172.17.5.254 as my default route ? the default gateway and my host are not one the same net . I tried the command " route add default gw 172.17.5.189 " , but it shows " SIOCADDR : Nework is unreachable" Thanks a lot
