BigIron RX(config)# int e 1/1
BigIron RX(config-if-e1000-1/1)# ip bootp-gateway 109.157.22.26
These commands change the CLI to the configuration level for port 1/1, then change the
BootP/DHCP stamp address for requests received on port 1/1 to 192.157.22.26. The device will
place this IP address in the Gateway Address field of BootP/DHCP requests that the device receives
on port 1/1 and forwards to the BootP/DHCP server.
Syntax: ip bootp-gateway <ip-addr>
Changing the maximum number of hops to a BootP relay server
Each BootP/DHCP request includes a field Hop Count field. The Hop Count field indicates how
many routers the request has passed through. When the device receives a BootP/DHCP request,
the device looks at the value in the Hop Count field:
•
If the hop count value is equal to or less than the maximum hop count the device allows, the
device increments the hop count by one and forwards the request.
•
If the hop count is greater than the maximum hop count the device allows, the device discards
the request.
NOTE
The BootP/DHCP hop count is not the TTL parameter.
To modify the maximum number of BootP/DHCP hops, enter the following command.
BigIron RX(config)# bootp-relay-max-hops 10
This command allows the device to forward BootP/DHCP requests that have passed through up to
ten previous hops before reaching the device.
Syntax: bootp-relay-max-hops <1-15>
Default: 4
