Ideally the maximum packet size and whether or not to run DPLPMTUD would be separate flags — in my use-case we have guarantees from the lower layer so don’t need to work upwards to discover the max packet size — but otherwise yes, this seems like a good step in the right direction!
After completing the configuration, run the following commands to check the maximum number of invalid IPv4 multicast protocol packets that can be saved and statistics about invalid multicast protocol packets: Run the display current-configuration | include multicast invalid-packet command to check the ma...
Tx buffer item size was hardcoded to 2048. If userspace manages to deliver larger packet, driver could go boom. Normally this doesn't happen because userspace sets MTU (at least on IPv4) to 1500. But in some strange case this did happen. Besides, user can set the larger MTU on the ...
If a packet is an IPv6 packet, or if a packet is an IPv4 packet and path MTU discovery is enabled, the path MTU value is used to determine the maximum size of the packet. Path MTU discovery initially sets the path MTU value to the actual route MTU value for the route. If packets ...
OnlyIPV4allows packet fragmentation. If a packet larger than the MTU is sent over IPv4, it will be automatically fragmented unless the do-not-fragment flag is set.IPv6does not allow fragmentation. If a packet size exceeds the MTU in IPv6, it will be dropped. ...

The maximum size of an Ethernet frame is 1518 bytes, which consists of the 14-byte frame header, 4-byte frame trailer, and 1500-byte upper-layerIPpacket. The size of 1500 bytes is the default Ethernet MTU value. Network layer protocols, such as the IP protocol, determine whether to fragm...
