Re: [Bluez-users] BT_ADDR Address Resolution

Hi Marcel,

The ARP will take place using BNEP frames right? i.e. an ARP packet
encapsulated in a BNEP frame with a destination address corrosponding to
a broadcast MAC address.

Assuming one PANU wishes to send IP traffic to another PANU. When this
BNEP frame encapsulating the ARP request arrives at the GN, is it
broadcast on all bridge ports?

Also does the bridge implimentation result in one broadcast per "port"
i.e. instead of one baseband layer broadcast (i.e. LT_ADDR = 000), we will have
as many broadcasts as the number of connected PANUs (i.e. one per
port)?

I hope I'm not sounding too confused.

Thanks for your explaination.

Regards,
Assed
