Protocol OSPF Ethernet Address 01:00:5e:00:00:05 01:00:5e:00:00:06 RIP NTP VRRP PIM-SM 01:00:5e:00:00:09 01:00:5e:00:01:01 01:00:5e:00:00:12 01:00:5e:00:00:0d • The Dell Networking OS implementation of MTRACE is in accordance with IETF draft draft-fennertraceroute-ipm. • Multicast is not supported on secondary IP addresses. • Egress L3 ACL is not applied to multicast data traffic if you enable multicast routing. First Packet Forwarding for Lossless Multicast All initial multicast packets are forwarded to receivers to achieve lossless multicast. When the Dell Networking system is the RP, and has receivers for a group G, it forwards all initial multicast packets for the group based on the (*,G) entry rather than discarding them until the (S,G) entry is created, making Dell Networking systems suitable for applications sensitive to multicast packet loss. NOTE: When a source begins sending traffic, the Source DR forwards the initial packets to the RP as encapsulated registered packets. These packets are forwarded via the soft path at a maximum rate of 70 packets/second. Incoming packets beyond this rate are dropped. Multicast Policies The Dell Networking OS supports multicast features for IPv4. IPv6 multicast is not supported. • IPv4 Multicast Policies IPv4 Multicast Policies The following sections describe IPv4 multicast policies. • Limiting the Number of Multicast Routes • Preventing a Host from Joining a Group • Rate Limiting IGMP Join Requests • Preventing a PIM Router from Forming an Adjacency Multicast Features 720
