[c-nsp] Recommendations for 12.0S version for 7500/RSP4/VIP2-50?

[Alex Rubenstein]

I've seen odd problems regarding AToM and L2TPv3 on later versions of 
12.0S. The issue is that the l2circuits are one way, the 7500 will never 
'hear' the packets coming in on the customer-facing port, thus never make 
it to the LSP or Tunnel. I opened a TAC case on this, but for whatever 
reason, no DDTS was made, and no fix as of yet.

The last IOS that seems to not be broken in this regard is 12.0.28S3, at 
least as of about 5 months ago. I recently tried this on 7500 with 
12.0.30-something, and had the same issue with a ATM-VP.
