IPv6 multicast: [41] The low 32 bits an Ethernet address for IPv6 multicast traffic are the low 32 bits of the multicast IPv6 address used. [ 40 ] : §2.3.1 For example, IPv6 multicast traffic using the address ff02::d uses the MAC address 33-33-00-00-00-0D , and traffic to ff05::1:3 goes to the MAC address 33-33-00-01-00-03 .
Cisco has ceased support and distribution of IGRP in their router software. It was replaced by the Enhanced Interior Gateway Routing Protocol (EIGRP) which is a completely new design. While EIGRP still uses a distance-vector model, it relates to IGRP only in using the same composite routing metric.
A multicast routing protocol is a mechanism for constructing a loop-free shortest path from a source host that sends data to the multiple destinations that receives the data. IPv4 uses Class D address (224.0.0.0 ~ 239.255.255.255) [ 2 ] IPv6 multicast provides the previous feature of IPv4 and a new IPv6 feature, allowing a host to send a single ...
