3.2.5 Enabling IP Routing Functions
The IP routing functions you can enable for ports on the ATX may
be any combination of the following:
• Off – no IP routing at all.
• On – IP routing, but no inter-router protocols.
• RIP – IP routing, with RIP enabled, allows the ATX to send out
broadcasts every 30 seconds advertising the networks it knows
about, the routes to those networks, and the number of hops to
get to there.
• Proxy – IP routing, with proxy ARP, allows the ATX to respond
to an ARP request on behalf of a device that is located on a
network behind it.
• BOOTP – Enabling the BOOTP relay option is useful in
environments where you have a diskless client and its server is
on a network on the other side of the ATX. When the client boots
up, it sends out a broadcast requesting the software it needs to
download. If BOOTP is not enabled, the ATX won’t forward the
broadcast to the network where the server is located. This may
also be used to relay DHCP frames.
• IPM – Enable IP multicasting. IP multicasting is the
transmission of IP packets to a host group. A host group is a set
of hosts identified by a single IP address.
To use LCM to enable IP routing functions for a port or port range,
starting from the LCM prompt:
8 192.138.217.50 255.255.255.0 00:40:27:00:06:9e
9 192.138.217.30 255.255.255.0 00:40:27:00:04:b4
