[c-nsp] ASR9K using XR 7

[Christophe LUCAS]

Hi,

I have had a forwarding bug (missing some PPPoE encaps without QOS enabled) with 7.1.3 with ASR9901. As said SMU must be read and taken into account.

Regards,
Christophe

We've been testing 7.1.3 for deployment onto ASR9Ks and NCS55Ks.

Similar features set to you it sounds, the standard SP features. No show stoppers on the 9Ks for us in 7.1.3 but I think a few on the NCS55ks. There are always plenty of bugs on XR, and they are different on ASR9Ks and NCS55ks. Yay!

For 9Ks on 7.1.3 there are minor bugs with BGP PIC not switching to the primary path, a CEF bug waiting 4 minutes to switch to the backup path, host name changes not being reflected on ISIS, and so on. Some of them are very niche and require the exact order of operations to trigger or FRR + TI-LFA + PIC etc. This is why I say they aren't show stoppers, they're unlikely to be triggered and there are SMUs for all we've encountered. So just look through the SMU list and see what's relevant yo your setup.

Cheers,
James.
