[c-nsp] NCS-5001 - MPLS L3VPN Issue

[Aaron]

Sorry about off topic, regarding the complaints about Cisco listed below, Please let me know whether or not Juniper is better about ensuring features work in their new products... and also, is Juniper better in handling things like this when you bring it their attention ?  how do y'all like JTAC over Cisco TAC ?

Just looking for your experience since I'm about to embark on that path.

Aaron

This paradigm only goes so far, Cisco have missed some very basic testing indeed. I mean, it looks to us like they've barely tested the code and just shipped it. We've got a nice race condition at the minute an amature programmer could spot. Processes getting stuck in an infinite loop and locking up the CPU.

It’s been years since IOS-XR was released on ASR9000's, no excuse now for basic features still not working. The TAC responses aren’t helpful either; things like "running an Inter-AS MPLS Option B and BGP-LU at the same time is not supported" - So we can have labelled VPN routes, or labelled GRT routes but not both? In this day and age! Someone once said to us “Inter-AS MPLS Opt C isn’t supported at all” - which we were running on the PE/ASBR under investigation. We’ve had bucket loads of issues/TAC cases (we are still opening TAC cases at a decent rate).

My mind is pretty set on this, their testing has been appalling (I’m obviously moaning at Cisco about this) – I’d like to know what others think.

Cheers,
James.
