[OLSR-users] DHCP on an OLSR net

[Gaspard, Bradley S]

I've been testing a plug-in I've written which forwards DHCP messages using OLSR. Mobile nodes that are already 'configured' start up a DHCP relay server (written in Python/Twisted) listening on port 67. When a DHCP Discover/Request message is heard it gets forwarded to the plug-in via TCP/IP IPC interface and flooded. [there is a random delay before forwarding to limit the number of configured nodes from forwarding the message]. A gateway node is configured to to unicast the DHCP message to the DHCP server which resides on a separate subnet not on the MANET. The DHCP Offer/Ack goes back over OLSR and the configured mobile node responsible for first forwarding the Discover/Request message broadcasts the response back to the configuring node. I've left out many details but that is basically how it works.

Is there any way for DHCP to work on an OLSR mesh? It seems like it
could propagate out from the DHCP server as each hop came up. A node
that wasn't part of the mesh yet would just send out broadcast
requests until it got assigned an address.
