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? -Brian
Seems that AT&T mobile has some problem announcing their network containing their only 2 DNS servers serving the mobile.att.net domain - the MX records won't resolve. (The 199.88.234.0/24 network) All email paging to AT&T wireless customers stopped working for that reason: I have queued up pages for them by the 100's going back to about 2pm today. I can't get to the "Messaging" section of their website either. Ouch. bye,Kai
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.
