The following configuration sets up RIPv1 with Dynamic Host Configuration Protocol (DHCP) Relay enabled. DHCP relay is used when no DHCP server exists on the immediate network.

When a local client sends a DHCP request, the XSR relays this request to the appropriate DHCP server specified by the helper-address. After the server responds, the XSR relays this response back to the local client. As described below, the XSR connects to the PSTN via a T1 connection with 12 associated channels comprising channel-group 0. This T1 channel group is presented to the XSR as a serial port and is configured similarly.

The T1 (serial port) connection is unnumbered, indicating packets from the T1 interface will use the IP address of the Ethernet interface instead of its own.
