Example 5a: HP ProCurve 2626 (H.08.53) one SSM receiver, one SSM source
In this example, we reconfirm that the HP switch fails to implement
IGMPv3 snooping fast leave correctly as discussed in previous examples.
Unfortunately, due to those problems, not much more of use is learned.
The traces
I ran tcpdump on all four hosts as shown in the following example
for one of the hosts:
tcpdump -s 1500 -w 12.tcpdump igmp or dst 232.5.6.7 &
This captures IGMP protocol messages and the (relatively low data
rate) multicast data for the group of interest.
Raw tcpdump traces are here:
host 10
host 11
host 12
host 13
