Mike,
Sorry. The E Series. Although, I do not have a lot of experience with the ML
sop I will look at that right now to see if that can do what I need.
Thanks for the steer,
Jim

Which ONS Ethernet card? E Series, G Series, ML Series? I'm guessing not
the ML series since you mentioned your ONS has little routing functionality.
On the ML Series, your POS interface would go down which would cause your
routing to re-converge.
I haven't tested a G Series, however; I was recently in Dallas for ONS
training and on the E Series cards, the Ethernet port stayed up during the
scenario you describe. During the same test, the way we got around the
lengthy convergence time was to use rapid spanning-tree.
HTH,
Mike
