--> In IPV6 hosts or devices uses neighbor discovery protocol to find out the Default Router or Default Gateway Address.
--> By Default hosts will select the first router that it learned from neighbor discovery protocol as a default router.
--> We can change this behavior by using Default Router Preference command in cisco routers.
--> This command is useful when we have multiple routers are connected on the same subnet.
--> To change the default router, just make default router preference high on the interface
Router(config)# interface ethernet 0/0
Router(config-if)# ipv6 nd router-preference high
