The first 4 bits of the IP multicast address are fixed 1110 and correspond to the high 25 bits of the multicast MAC address. In the last 28 bits of the IP multicast address, only 23 bits are mapped to the MAC address, so 5 bits of address information are lost. As a direct result, 32 IP multicast addresses are mapped to the same MAC address.

When two routers exchange database information through DD packets, they form a master-slave relationship first. The router with a large id must be the master and the master and slave bits must be MS.
