Hi Guys,
I'm trying to improve the stability of my MLX/XMR under layer2-loop-conditions and came across the "vlan-cpu-protection"-feature. Does anyone know about the side effects of vlan-cpu-protection in combination with routing protocols like OSPF and BGP or with vrrp? The manual says "When using routing protocols (like OSPF etc.) on a specific VLAN, you need to disable VLAN CPU protection for it to work." I guess this means that during a flood condition routing-protocol-packets might get lost as they are filtered - or better rate limited - on their way to the cpu like all ordinary packets. Doesn't sound too bad. I'd prefer a layer3-protocol-flap over a system that's lost because it's cpu is on 100% and it doesn't even switch packets nor does it route anymore at all. What are your recommendations? Any pros / cons for the feature? Gunther
