• Unknown traffic in IP Subnet range
• Unknown traffic hitting the default route entry.
• Multicast NDP packets
• NDP packets with destination MAC is multicast
• DST MAC 33:33:XX:XX:XX:XX
• NDP Packets in VLT peer routing enable
• VLT peer routing enable cases each VLT node will have route entry for link local address of both
self and peer VLT node. Peer VLT link local entry will have egress port as ICL link. And Actual link
local address will have entry to CopyToCpu. But NDP packets destined to peer VLT node needs to
be taken to CPU and tunneled to the peer VLT node..
• NDP packets in VLT peer routing disable case
• NDP packets intended to peer VLT chassis taken to CPU and tunnel to peer.
The following table describes the protocol to queue mapping with the CPU queues increased to be 12.
