Colton, This was 6+ years ago, SAOS 6.14, so I don't know it might be better now. We changed to Cisco ASR920 and it was a night and day difference - we now have 90ish ASR920s in production but are migrating toward the NCS540X. Patrick Sat, May 29, 2021 at 10:13:13AM -0500, Colton Conor wrote:
Patrick, How long ago was this, and what code were they running? What do you recommend for aggregation then? On Fri, May 28, 2021 at 9:17 PM Patrick Cole <z@amused.net> wrote:
We ran a medium sized mpls network using ciena 3900 and 5000 series boxes on our microwave network. Nothing but problems, the mpls code was just not mature enough and our radio network had the boxes falling apart at the seams as storms rolled through. At that time they didn't support FRR or proper CSPF so everything had to be manually engineered active standby LSPs. Not sure if things have changed now. These boxes have Nortel vintage and they seemed best delloyed using PBB TE as it was mature. As an NID though they are not a bad option but not in core or aggregation IMHO.Â

Yes, I was surprised as you that they have these routing features. I was also surprised they had multiple boxes that compete with aggregation devices like the ACX5048. The question is how good is Ciena's MPLS, switching, and routing stack compared to the established players of Juniper, Cisco, and Nokia? Ciena is no small company, so I think they would have the resources to make it happen. On Fri, May 28, 2021 at 12:32 PM <aaron1@gvtc.com> wrote:
Wow, ciena has the means to implement SR and MPLS services? I mean they run the underlying LS IGP to signal those SIDâ**s ?? I didnâ**t know that. I may look at them in the future then. I thought Ciena just did some sort of static mpls-tp or somethingâ*¦

We use Accedian as NIDâ**s with SkyLight director for PAA (SLA stuff)â*¦and uplink those into our network at (yester-year, Cisco ME3600â**s and ASR9000â**s), but now, ACX5048 and MX204
