We have a network configuration which looks like: Network A Network B ----------- ----------- | | ----- ------ ----- |Sun|----------|Cray|----------|NSC| ----- ------ ----- We're currently using Network A as the default route to the Cray, but we'd like to switch to using Network B as the default route. We're trying to use gated on the Cray to listen to information from the NSC router and set its default route there, but if the NSC box dies, then the default should switch (temporarily :-)) back to the Sun. As a test of the default route changing ability of gated, we ran a test between a Sun (on Network B) and the NSC box and gated properly changed the default route to the NSC, and then reverted back to the old route when we disabled the NSC box. However, the Cray, using similar configuration information for gated, fails to do this even when it heard of a lower cost route (of 2 versus 13) through the NSC box. I've included the configuration file for gated at the bottom of this message for the Cray. Normally the Cray uses static routing - will gated override these static routes when it is running? On a separate note, has anyone ever examined the route metrics issued from a NSC box via SNMP? The results are most interesting (well, I'd never heard of a route metric of 80 :-)).
