Hi guys,
I hope you're doing well. I'm new to the 7280r family of Arista devices. I just got a DCS-7280QR-36, and I'm wondering if it can really support full DFZ in both IPv4 and IPv6?
I run the FlexRoutes commands "#ip hardware fib optimize prefixes profile internet" and "#ipv6 hardware fib optimize prefixes profile internet" and after that I restarted the layer3 forwarding agent with "#agent SandL3Unicast terminate", but now only with full IPv4 routes (and IPv6 default) I do see 95% utilization in the Jericho ASIC, I haven't enabled full IPv6 to about over 100% utilization. I was wondering if I'm missing something or is it just that the hardware can't support full DFZ tables.
