Re: IE R&S WB V5 Vol 2 Lab 10

Hey CL,

always a challnge to troubleshot in the dark.

Not knowing your config or what you have done.

Standard steps for a bug like this are KISS.

sh cdp neig
sh ip int brief
sh vlan brief
sh int trunk

Sometimes when all else fails, write the config and reload. The
re-convergence can work miracles.
If you want more input feel free to post the results of the above commands
including running configs.
You can unicast me if you prefer not to flood this list.
