We are looking at deploying the QFX5110 and/or QFX5200 as MPLS LSR - pure P - routers.
Do any of you have pratical experience from production enviroments running such platforms in roles that are slightly outside the box?
The number of P routers is app 15 connected in rings, which means each P-node will have 2, 3 or 4 neighbors.
From the datasheets I see that the QFX supports either 8k or 15k transit LSPs
Im looking at a way to estimate the total number of LSPs and get some numbers on LSPs on the most loaded nodes.
- any suggestions?
-- any good tools that you can recommend?
-- worst case for me would to boot 15 vSRX and build the topology to see the LSPs
The number of nodes in the IGP is app 50 including the P-nodes and a lot of PE nodes.
I assume I get a label mapping for each loopback on each node in the topology.
How big would you say a Core P-router should be?
How modular would you need a P-node to be?
Any suggestions will be appreciated
