I concur on WanPro. Almost every practice test I've tried has a few errors,
but most are pretty good anyway.
I wasn't thrilled with the Sygress/Osborne "Test Yourself" test, I thought
it had some pretty serious errors
when I was studying for CCNA.

I did try to clear the sas on both sides, and it didn't seem to have an effect.
I'm using nat 0 so that the client on the inside is not NATted at the
external interface of the PIX, which would break the IPSec tunnel. I am

This isn't really a fair question. We'd need to know things like the current load on
the router, other processes/protocols running, memory, link state database size, area

The 239.255.255.255 is the highest in that subnet. D class starts at 224
(1110) and then E class would start at 240 (). This makes the D class
range of addresses: 224.0.0.0 through 239.255.255.255. Therefor if D class
addresses are used for multicasting then the 239.255.255.255 address woul
