[c-nsp] IOS Trains differnces

[Lamar Owen]

On the original subject of Trains Difference, here's an obscure one for you.  

I'm running four routers on an OC3 WAN link, and am running 1+1 APS at both 
ends.  One end has a 12012 and a 7507; the other end has a 7507 and a 7401ASR.  
The 7401ASR and the 7507 on the far end are running 12.4 mainline, with the 
7507 and 12012 on the near end running 12.0S.

12.0S has a later version of the APS protocol, PGP, than 12.4 mainline does 
(version 3 for 12.0S, and version 1 for 12.4 mainline).  Go figure.
