[c-nsp] Thoughts on the ASR9902?

[Drew Weaver]

Hello,

We bought one and regret it mightily every single day.

Ours specifically had bad memory in it, it took a year before they/we figured that out, lost our SNT over that year while it was acting insane [and we couldn't deploy it] and then even after they RMA'd the router because it was faulty the entire time we owned it we were provided an insane quote to renew our SNT. Had it 15 months now, it's routed exactly zero packets.

It's basically a 8 port 100GE router, all we wanted to do was configure it for 3x100GE +10x10GE per 'slice' and that was impossible, instead they advised us that if we want 6x100GE ports we should configure the slices asymmetrically [i.e. one slice 4x100GE and the other slice 2x100GE+10x10g+10x10g] but that of course reduces redundancy if you planned on using port channels across the slices [assuming that the slices fail independently of one another which wasn't our case with the bad memory as all of the ports went down at the same time even though we were advised that the two slices were independent by TAC].

If I had it to do all over again I probably would've just purchased two Arista 30x100GE switches [which with the right model can also do full tables] for the same price as one 9902.

If I couldn't do that I would probably just get whatever the smallest ASR99 is with 2x4 port 100GE line cards in it and just be done with it.

Thanks,
-Drew

We're in the process of looking for another small (form-factor) router that will be able to handle multiple full BGP tables and has some 100G interfaces on it.  We're currently using an ASR9901, which is working fine, but Cisco in their infinite wisdom has just put that on the end-of-sale list.

On our last call, they proposed the 9902 as a reasonable replacement for the 9901.  On paper it looks ok -- typical 'new' Cisco "you can use this port, or those 2 ports, but not both", etc.  The other thing that I don't really like is that it can have 2 route processors.  But, they're not interconnected in the back plane.  So if you put both processors in, you basically have 2 routers in one chassis, each with their own sets of ports.  Unfortunately, there's not a lot of other options in the 9k range that aren't large-scale chassis routers.

It sounds like it's a fairly new platform, but wondering if anyone has any hands-on experience with them yet.

Thanks

Shawn
