[cisco-voip] vg224 vs vg248

[Carter, Bill]

On interface F0/0 you could add "no keepalive" .  This will make the VG
think the interface is always up regardless of the interfaces true
state.
 
- You can use the MAC address for int f0/0 to configure the voice ports
in callmanager. f0/0 doesnt need to be up for the ports to work
(although I didnt try registering the ports with f0/0 down.. will try
that next)

		Ok now that i've had a chance to pop one in the lab,
here's what I found:
		
		- EIGRP support has been recently added to the feature
set for the VG224 IOS.
		- As stated, you can bind int L0 to sccp
		- You can use the MAC address for int f0/0 to configure
the voice ports in callmanager. f0/0 doesnt need to be up for the ports
to work (although I didnt try registering the ports with f0/0 down..
will try that next) 
		
		This all seems to work as I expected, depends on what
your goal is with the redundancy. I need to figure out if there is any
tinkering I can do with timers to make the routing switch over faster on
a failure.
		
		 Our requirement was for redundant links, so that
network ops can upgrade software on their equipment and not cause an
outtage, (as well as cover for certain hardware failures) . If your
power supply goes bad, this doesnt help much :)

			Interesting, I just got a note back from my SE
with what I'm sure was 'cut and pasted' advantages to the vg224 and it
had redundancy in there. It will be interesting to see what you find
out.
