Hi Team,
I have put in SUP-114337 for issues with my recently installed CCR2216.
We have the following setup:
- 80G (2x40G) LAG to 2 x CRS354's. These are mLAG's on the CRS side.
- 20G (2x10G) LAG to ISP A
- 20G (2x10G) LAG to IXP A
- 10G to IXP B
We have approx 17 x IPv4 & IPv6 BGP peers/sessions, and around 580K routes. As soon as we enable L3HW offloading under "Switch" settings, the device stops routing all traffic and reports L3HW routes are full and crashes. We have tested 7.8, and all 7.9rc versions - the only way to fix is to turn off L3HW and reboot the device. We have even tried to disable all bar 3 of the BGP peering sessions where we end up with less than 10K routes overall, and the device still randomnly crashes with L3HW turned on.
With L3HW offloading turned off, we can still route approximately 20Gbps at 20-30% CPU, however this would be substantially reduced with being able to turn on L3HW.
Thanks!
