Maybe more like medium, but if you know that you won't grow beyond a certain size and growth trajectory, chassis would make life easier. If you are dealing with some compute and you know how many racks you have, same thing. In fact with small networks, you are actually starting out with more than

True. Small networks would just have a single pizza box and call it a day. I haven't looked that deeply yet. I was assuming you could just start with a single pizza box and add more on as requirements matured. It certainly gets more complicated quickly if you can't do that. - Mike Ha

BGP AFI or SAFI for advertising BFD status

2024-12-21 Thread Douglas Fischer
I'm looking for a way to propagate the status of BFD sessions running on one router to another via BGP. Considering the versatility of BGP, I'm sure this is possible. But when researching BFD and BGP, my biggest difficulty was avoiding documents that talk about how to use BFD as a trigger for det

Oh, so you're saying that small networks benefit more from a traditional chassis than a distributed fabric? I would have thought it the other way around in that you could start with a single pizza box, then add another appropriate to the need, then another appropriate to the need as opposed to t

When you say distributed router fabrics, are you thinking OCP concept with interconnect switch with ATM-like cell relay (after flowery speeches about "not betting against Ethernet", or course)? https://www.youtube.com/watch?v=l_hyZwf6-Y0 https://www.ufispace.com/company/blog/what-is-a-distributed-

It's just tradeoffs. Many of the benefits ( smaller failure domains, power savings , incremental expandability ) can be counterbalanced by increased operational complexity. >From my experiences, if you don't have proper automation/tooling for management/configuration and fault detection, it's a n

Uu that's sounds great! Exactly what I was wondering. Create a VRF called BFD-RouteServer on each PE, on that VRF on each PE activate the IPs of Route-Server, and activate de BFD Sessions with the participants connected to that PE. And then, add a PBR deviation of BFD coming from participants
