By defaultIn order to help maintain hygiene across the peering fabric, all peering participant ports are subjected to a standard layer-2 filtering policy to limit frames that are considered unwanted at the peering fabric.  Below is a list of frames that are filtered (dropped) by default: .  This list is expected to growrevised as necessary.

In general peers are expected to send only  IPv4 (0x0800 ), IPv6 (0x86dd ) and ARP (0x0806) ethertypes.  Other frames types will be dropped.
