RE: No SOLUTION till DATE for this SCNERIO ???? Challenging

Thanks SCOTT,
Just one query, what do you guys suggest, because everyone is saying that this
is a BUG in CISCO IOS
so in that case what should a person do ?

1. Just paste the standard working configs verify the solution one by one ,
and come out of the lab.
2. Do a work around which may deduct the marks because both the technologies
don't work together at the same time
3. ask the proctor ? because he must know the bug , but again he can make your
day worst by guiding you into a wrong way ?
4. Just drop one Section, lets say the internet and dont risk the entire
MULTICAST because of that 0.0.0.0 default route :(

please reply back since I have less then a week now :(, I hope I don't
encounter into this situation in the real LAB ?
