Enabling A Vci On A Cable Interface - Motorola BSR 2000 Configuration And Management Manual

BSR 2000 Configuration and Management Guide
The host and mta VCI options are used to configure a CPE host or MTA gateway IP
address (giaddr) for the cable interface. During the DHCP process, the DHCP relay
agent requests an IP address in a particular subnet by inserting the cable interface
giaddr into the DHCP requests from CMs, hosts, and MTAs. The primary IP address
is always inserted in CM DHCP requests. The ip dhcp relay information option
command must be enabled to allow the BSR to determine what type of device
originated the DHCP request. The primary IP address for the cable interface is
inserted into DHCP requests by default.
