Hi Otto,
I have tweaked a little on our ISIS links to/from our routers in ASIA. Hopefully it will
help in future cases. I have a little problem understanding what other problems you have
been observing and or what you would be expecting to see in case of errors in network and
time for network to converge.. could you please help me understand your microdep graphs
etc.
Thanks..
