Figure 1-2. Requesting an IP Address from the BootP Server (Group Access PVC)
5. The upstream router sends the IP address and subnet mask to the AN/ANH or
ARN router in a BootP response message.
6. The AN/ANH or ARN router assigns the IP address and subnet mask to any
serial interface that receives a BootP response.
7. The AN/ANH or ARN router stores these IP addresses, along with the IP
address of the next-hop router, in RAM.
If more than one serial interface receives a BootP respo nse, the AN/ANH or
ARN router assigns an IP address to each interface.
