Re: Building and configuring reliable linux routers?

Curently one linux box with two ethernet interfaces is routing between
the two vlans, what I'm proposing to do is enable vlan tagging on both
ports from the switch. Then each physical interface becomes 2 virtual
interfaces, so I basicly have 4 interfaces. Now I want to bridge the
two physical ports and use STP so only one is active at a time. Basicly
failover at level 2, rather than level 3. Will this work to cover stuff
like bad cables?

I also forgot to add that I want to setup some way to monitor the
status, if one of the ports goes down, it needs to be brough to
someones attention to fix the problem before the second link goes down
and the labs offline. I think SNMP is the answer here, but I'm really
having trouble getting my head around it.

I'm just doing this to learn really and to decrease the likely hood of
problems caused by bad cables and people unpluging the wrong cable at
the patch panel. I'm trying to get it somewhat robust because most of
the other students who are working in the lab don't have a clue. The
instructors are not much better and the IT department don't want
anything todo with the lab.

The end of the post really has nothing todo with my problem, just
alittle extra info on the setup.
