Linux Ethernet Bridging - Oct 2017 - [Bridge] Linux Bridge Static FDB move

Hi Everyone,


Is it possible to program the FDB entry in Linux Bridge which is static,
non-local and doesn't move to new interface when the same source MAC packet
comes on a different interface in the same bridge  ?


I tried programming the MAC as permanent that prevents the moving of MAC to a
new interface in the same bridge, however it treats the MAC as local and
doesn't do the forwarding ?


Thanks,

Viraj

AFAIK no.
Bridge supports static fdb entries, but br_fdb_update() updates their
dst even for static entries.

Yes, local entries will deliver frames to the bridge device itself.
