   Our NSC router (DX4130) does not update its routing table when it
receives an ICMP redirect message (host redirect or network redirect).
The ICMP redirect comes from the routers default gateway (on the same
subnet) and gives the address of a better gateway on the same subnet.

   I dont find anything in the RFCs about what a gateway should do when
it receives an icmp redirect, but a gateway must be intelligent and
optimize the traffic on the network...
   NSC says the ICMP redirect messages are only for hosts.

   Can somebody help me? Thank you.
