If a dedicated interface must be specified, this can be done by -i or using %. As you perhaps already know, ICMP echo-request packets are more accepted by firewalls or ACLs on routers inbetween than UDP packets. Note: unlike some modern versions of IPv4 traceroute, which can use ICMPv4 echo-request packets as well as UDP packets (default), current IPv6-traceroute is only able to send UDP packets. Setting up a bonded network interface on RHEL 7. To see any available network interface that can be monitor using option -D : tcpdump -D 1.eth0 2.usbmon1 (USB bus number 1) 3.usbmon2 (USB bus number 2) 4. Then on client send a multicast packet (use the script in link below to troubleshoot) NOTE: the UDP packet seems malformed so not sure if servers will be able to read.
If you dont see any packet coming in, then the multicast packet are not forwarded (assuming that.
It's a program similar to IPv4 traceroute. On server side, start a packet capture : tcpdump -i
This older program is normally included in package iputils.
