Re: [B.A.T.M.A.N.] Manually Updating Translation table

["Linus Lüssing" <linus.luessing@c0d3.blue>]

Hi,

Currently, no there isn't. The only thing you could do to manually
add an entry from inside a node is by crafting a dummy packet with
the desired ethernet source address and transmit it on bat0. That
way batman-adv would add that MAC address. Deleting only happens
after a timeout though, no way to force it manually.

In case you are thinking about implementing such a feature:
The Linux bridge has a feature like that to update the FDB
(forwarding database, for unicast addresses) or MDB (multicast
database). It uses netlink for that and you can use
/usr/sbin/bridge to easily add and remove entries from userspace.
That'd probably be the approach to mimic in batman-adv for such a
feature.

Regards, Linus

PS: Out of curiousity, could you share what you'd need such a
feature for?
