Section VII: Routing 359
Guidelines
These guidelines apply to the BOOTP relay agent:
ˆ A routing interface functions as the BOOTP relay agent for the local
clients in its subnet.
ˆ You can specify up to eight DHCP or BOOTP servers.
ˆ The TTL for BOOTP request relay packets is preset on the AT-9400
Switch to 4. It cannot be changed. Routing interfaces discard BOOTP
requests when the TTL is decremented to zero (i.e., after 4 hops).
ˆ Because both BOOTP and DHCP use BOOTP messages, the BOOTP
relay agents can relay both their packets.
