L1 and L2 routers elect separate DIS's.

DIS uses a specific Ethernet multicast address to communicate with other routers on the broadcast network.

If a new router starts up in a LAN and has a higher interface priority, the new router preempts the original DIS and becomes the DIS.

In broadcast multi-access networks, such as Ethernet, one router is elected as the DIS and a second router as the backup DIS.

To give IPv6 traffic preferential routing over IPv4 routes.

To allow core routers running only IPv6 protocols to carry IPv4 traffic.

To give IPv4 only routers the ability to route based on IPv6 addresses.

To allow IPv6 traffic to pass through an IPv4 network.
