Losing default gateway

[grega]

Has anyone had any experience of Solaris "losing" its default gateway?

I know this can be done using route delete... or route -f, and can happen if the system is rebooted and /etc/defaultrouter doesn't exist.

We can't establish if either of the above route commands were executed by anyone, but I was just wondering if there's some Solaris "characteristic" which may cause default gateways to be "lost" from the routing tables.

You are using "routed" and switching over shared addresses ?
there are a known issue (default route lost) with this.

yes it seems that "routed" is not running in your system ... if no defaultrouter is specified, solaris try to run "routed" to build the routing tables, if you only have one network interface or the file "/etc/notrouter" exists, then solaris start "routed" in quiet mode, if you have more than one network interface card or the file "/etc/gateways" exist solaris start "routed" in server mode and advertised by the router discovery deamon, ... by the way avoid "routed" in any mode different from quiet mode, or turn it off, because routed has no access controls a host running in quiet mode "routed -q", listens and learn but doesn't talk with other hosts or devices, without the quiet mode it can advertise routes and take everthing we listen by true ..., a confused host can be very nasty for your network.
well sorry you want things about your problem, I only know 2 issues about lost of the default route when "/etc/defaultrouter" exists and is okay, the one with the routed deamon a another with when a Anex terminal server is present in same network that seams also not to be the case, so please sorry but I can't help you one this one.
