Babel is a routing protocol, and it is carefully designed to not carry any
extraneous information -- just the strict minimum that is needed for
routing.  Since Babel doesn't need to associate neighbour interfaces to
nodes, it doesn't.

There are many solutions to what you want to do.  The simplest would
probably be to have a dedicated protocol that periodically multicasts its
Babel router-id.

You could also send the router-id as a sub-TLV of Babel's Hello TLV.
Sub-TLVs 224 through 254 are reserved for non-standard extensions, and the
place in the code is the function send_hello_noupdate in message.c.
