IPv4/IPv6 multicast

AMRES has connected to IPv4/IPv6 multicast backbone via its link towards HungarnetWe are receiving many IPv4 multicast sources from other Europe NRENs and some commercial multicast sourcesProblem: currently there is no active IPv6 multicast sources among all Europe’s NRENThe only IPv6 multicast group FF1E::1:F00D:BEAC is used for testing purposes Every NREN can be source to or receiver from this test multicast group. In this way IPv6 connectivity can be tested and monitored.
