Usage Guidelines

A DHCP client can obtain the default route through the DHCP server to dynamically update the routing table. The next-hop address of the default route is the DHCP client's gateway address carried in Option3.

The default route that a DHCP server delivers is the user network router (UNR) route with the default preference 60. You can run the dhcp client default-route preference command to change the default route preference.
