[c-nsp] Recommend IOS for 7200?

[Howard Jones]

Oh fount of hard-won experience,

For a general dogsbody (LNS, BGP, OSPF) SP router, what is the current
recommended IOS version for stability? I am looking to upgrade a couple
of ancient NPE-225 routers to a current IOS. Should it be 12.2(25)S15?
or is there something else I should look at. Aside from the LNS, there's
nothing particularly special it needs. L2TPv3 might be nice, I guess.

Can anyone suggest/recommend any other release to look at?

Best Regards,

Howie
