Specifying the multicast address as the destination address for RAs
About specifying the multicast address as the destination address for RAs
An RA uses either of the following destination IP addresses:

Multicast address 224.0.0.1, which identifies all hosts on the local link.
By default, the destination IP address of an RA is the broadcast address. If all listening hosts in a local area network support IP multicast, specify 224.0.0.1 as the destination IP address.
