Delete multiple default gateways

1. Obtain how many gateways

   • # odmget -q "attribute=route" CuAt
     
     CuAt:
             name = "inet0"
             attribute = "route"
             value = "net,-hopcount,0,,0,192.168.0.2"
             type = "R"
             generic = "DU"
             rep = "s"
             nls_index = 0
     
     CuAt:
             name = "inet0"
             attribute = "route"
             value = "net,-hopcount,0,,0,192.168.0.2"
             type = "R"
             generic = "DU"
             rep = "s"
             nls_index = 0
       

2. If there are more than one, need to remove the excess route

   • # chdev -l inet0 -a delroute="net,-hopcount,0,,0,192.168.0.2"
     Method error (/usr/lib/methods/chginet):
             0514-068 Cause not known.
     0821-279 writing to routing socket: The process does not exist.
     route: not in table or multiple matches
     0821-207 chginet: Cannot add route record to CuAt.
       

3. Then verify again

   • # odmget -q "attribute=route" CuAt
     
     CuAt:
             name = "inet0"
             attribute = "route"
             value = "net,-hopcount,0,,0,192.168.0.1"
             type = "R"
             generic = "DU"
             rep = "s"
             nls_index = 0
