How do operators configure their equipments to treat
ICMP packet too big generated against multicast and
unicast?
Note that, even if they do not enable inter-subnet
multicast in their domains, the ICMP packets may
still transit over or implode within their domains.
Note also that some network processors can't efficiently
distinguish ICMP packets generated against multicast and
unicast.
