[f-nsp] SLX 9640 experiences

Hi Rob
As I’m currently very involved in the SLX implementation from Init7 side, I’ll answer this one.
We still have some more boxes to migrate, so not finished yet.
We have had and still have our own load full of TAC cases.
As you described I have made very similar experiences with the support.
It usually consumes a lot of time and effort to prove that something is really broken and indeed needs to be fixed by a software patch.
Positives I see similar points as you.
Perhaps one great thing to mention is the TPVM where you can tcpdump on traffic and do other stuff.
Negatives:
- Still experienceing MPLS LDP issues and instabilities
(sometimes not all FEC entries get installed and after two or three days without change they get poulated)
- ARP resolving not always working in P2P or P2MP bridge-domains (via MPLS LDP)
- Three to four unexpected reloads so far either due to route-map changes or just random after receiveing certain BGP NLRI Updates.
- MCT RACL Bug still not fixed after almost three months
- Also had issues with 3rd-party transceivers
- Traceroute gets blocked under certain conditions (still under investigation)
- IMHO not enough transparency regarding different software trains and releases and how and if the fixes get ported into feature-releases.
As for the rollback, I think there is some feature they call rollback and checkpoint.
So you can manually define a checkpoint and later revert to it via rollback.
IMHO not completely thought through or finished developing.
Also not sure if it already supports MPLS configuration as well.
We are also keen waiting on the RPKI feature.

Lino / Init7
