Summary: problems with ethernet interface metrics

I got just two replies. One suggested that I set a default route. I should
have said that we do not want to use static or default routes because we want
automatic failover to the Suns in the event of the main router going down.
Also, due to the large number of machines and networks, static routes are NOT a
long-term option.

The second reply was right on the money. Bugid 1187668 describes this problem
exactly. It's a bug in in.routed. I checked the latest SunSolve CD (2.8.3,
July 1996), but unfortunately I couldn't find a patch for it.

Our options now are to live with it or use default/static routes till we can
upgrade to Solaris 2.x, or find an alternative to in.routed. I may see if I
can get around it using gated (our long-term goal is to dump RIP entirely and
go to OSPF anyways).
