Pete,
thanks for your useful and informative reply. A decent example is worth
a paragraph of explanation to me :-)
Whilst I would love to do as you suggest, unfortunately my switches only
have 2 GbE ports each. My hope was to put the routers in the GbE ring,
as otherwise my routers will be bottlenecked by plugging into 100M ports
on the switches. As most of my traffic goes through the routers this
would be a big issue.
I suspect the only way I will really nail down what I can and cannot do
will be to get some new switches and build a router and start playing
around. The thing that I think is most likely to break is that I already
use vlans and carp, and so I will have to work out the proper way to
layer physical, bridge, vlan and carp whilst still making sure that
packets keep going round the ring.
Unless reyk@, porter of the rstp code for bridge, can tell me different...?
