A router interface configured as a DHCP client supports the following service types: VLL, VPLS, and VPRN. These services use a GRE SDP as a transport tunnel.
When a DHCP client is enabled on a router interface and an address is learned by the client, there is no configuration required in order to terminate GRE SDPs on that interface IP address. GRE termination is enabled on a DHCP client address when the client learns the address. For information about configuring services over a router interface enabled as a DHCP client, see Services over Ethernet with DHCP client.
