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.
