a (sub)set of possible solutions is: 1) write simple script performing default gateway health checking (pinging) and adding/removing default gateways 2) use gated 3) use znyx cards (http://www.znyx.com) -- dima.

What are the various options for load balancing across multiple interfaces which are connected to distinct switches/routers on a Solaris box? FEC/trunking wont work because the connections are to difference switches. Multiple default routes in Solaris appear to behave badly when one of the dest's is down, such that the route is not removed from the routing table and traffic is still sent in that direction (subject to TCP behavior), and it's round-robin versus something more interesting like MAC-hasing.
I think I can do equal cost multipath with two default routes in Gated as well, but I'm not sure if Gated is any smarter about removing an unreachable route. Will eqmp work if I'm injecting two defaults with OSPF?
Any other ideas?
