I don't think you need the dlep_radio at all.

This will spam your logfile pretty quickly... don't complain when you
have a few megabytes of log after a while.

the "lan" option is not valid for the section "interface".

Maybe you are thinking about setting an IP address on the loopback in
the network config?

So you want both "lan" and "wan" a mesh interface?

Why do you want to run dlep_radio?

the idea is that you set the IP addresses via the network config.
Olsrd2 will monitor all its interfaces and automatically grab
addresses that are allowed (you can set patterns in the olsrd2-config
what is allowed).

run "olsrd2 --schema=interface.ifaddr_filter" for the rules which
addresses will be included in Hellos and "olsrd2
--schema=olsrv2.routable" for the rules which addresses will be
"routable" and distributed "end-to-end".

Try the telnet port of olsrd2 (see config above ^^). e.g.:

echo /nhdpinfo neighbor | nc 127.0.0.1 2009

or connect to the telnet port and use the "help" command... e.g.

"help" (for generic help and a list of available commands)
"help <command>" for help text for an available command.
