Does anyone have any recommendations for taking a class/training on the VOIP
stuff ?
I'm looking for something Cisco oriented, but if someone has something good
to
recommend on more general implementation options, and design for different
protocols like SIP/H.323/MGCP, etc, that would be good too.
Since your question already assumes these port ranges, it would
mean your question is really whether NetBIOS over TCP/IP can
be routed. And as such, it can, just like any other IP traffic.

To be honest, I don't like them :-(

the final version once available, I had no problems clearing any of them.
And I don't think the problem was with my preparations either. The few exams
I took were rather poorly structured,

Let me say up front, I don't have much experience in MPLS, I have
only played with it in the lab and not all that extensively either.
But CN is simply trying to get an idea of what to expect to go that road.
Is "nrf" saying not to advance in this field by studying Cisco's way of
emphasising MPLS ?
hmm, don't know the whole story, but once you redistribute ospf into rip and
you mess up filtering on the interface, wouldn't that allow you to see the
redistributed routes on the router connecting to that interface ?
It's just another way to see whether what you implemented actually does
work...

You're correct, however if there are route changes happening constantly
you don't want the router to keep sending updates as it might exhaust the
peers.
The interval is used so there is a limit of how often the updates are sent

of how often the routes actually change.
