Configuring TFTP and BOOTP Servers
Adding Client or Relay Information
Figure 5-4 Example Configuration: Relay Entry
The following information is added to the /etc/bootptab file on
BOOTP server A:
defaults: ht=ether
all_hp:\
tc=defaults:\
ha=080009000000:\
hm=FFFFFF000000:\
bp=15.4.3.136
others:\
tc=defaults:\
ha=000000000000:\
hm=000000000000:\
bp=15.4.3.142
The all_hp entry causes bootrequests from HP workstations (machines
with hardware addresses that begin with 080009) to be relayed to IP
address 15.4.3.136 (server B). Bootrequests from other hardware
addresses (presumed to be non-HP machines) are relayed to IP address
15.4.3.142 (server C).
The following information is added to the /etc/bootptab file on
BOOTP server B:
xterm02: hn: ht=ether: ha=08000902CA00: \
ip=15.19.8.39: sm=255.255.248.0: \
gw=15.19.8.1: ds=15.19.8.119: bf=/xterminal:
