[c-nsp] IOS XR 4.3.0 or 4.3.1

[Shane Heupel]

Adam,

We didn't abandon 4.2.3.  We just purchased our ASRs and they came with 4.3.0 on them.  After reading through the downgrade procedure, I am somewhat hesitant to go through this procedure if there are no major issues with the 4.3 release.  As far as bugs are concerned, I don't have experience with any but remembered reading a post the other day that stated there were some fixes in 4.3.1 that had not been addressed in 4.2.3.  If 4.2.3 is the most stable version then I will downgrade.  I was just trying to avoid it if possible.  

Thanks,
Shane

Shane, Jared,
I guess we all have been told by our SEs that the 4.2.3 is the safe harbor. 
So I'm really curious what bugs made you abandon 4.2.3 and made your choice to rather go with 4.3.x instead. 
Would you please share the bug IDs or short description of the problems please?

As the only one I'm aware of -that has a fix in 4.3.1 is the manual Remote-LFA functionality using te-tunnels:

Thank you very much

I would like to know if anyone running BGP on IOS XR 4.3.0 or 4.3.1 and if so, are you having any issues?  We are being told the most stable version for BGP is 4.2.3 but I've also heard of some bugs with this version that have been fixed in 4.3.1.


Thank you,
Shane
