The EoS/EoL announcement for SRC just went out yesterday. 
Recommended migration plan is now SRD and SRE (when it does 
come out).

We're generally happy with SRC5, particularly on the NPE-G2 
platform. We have it running on the NPE-G1 and the NPE-400. 
Save for some BFD madness, no major drama.

If you want to remain with the 12.2SR* branch, though, 
expect to move to SRE if you're looking to support 4-byte 
ASN's.

Cheers,

Mark.
