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.
XSR(config)#controller t1 0/2/0
