Adding VLAN tags to stp traffic

[Emerson Yesupatham]

Friends,

I have a router device, which has lan bridge (br0).

br0 has few ports in it, STP is enabled and VLAN filtering is enabled for the bridge and the ports in it.

one of the port (eth1) is configured as Egress Tagged. However the STP packets going in this port(eth1) are untagged. I want those STP packets to be tagged with a VID. The STP is kernel space. 

Any method to tag the STP traffic? ebtables can be used? 

please suggest.

thanks

Emerson

Are you not able to achieve it using some kind of nft tables & rules?

Thanks Anil . I am not familiar with ebtables yet.

Looks like it should be possible with ebtables rules... 

Not much material in internet either. 

Basically need to push and pop vlan HDR for outgoing and incoming stp traffic respectively.

Since bridge vlan filtering is enabled, i thought the bridge will do the above but it doesn't...

Let me try.. if any material on ebtables please point it.

Thanks

Emerson
