Re: [Linux-ATM-General] [Br2684] problem with the br2684ctl

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Yes I've compiled with 802.1d Ethernet Bridging but not with 802.2 LLC encapsulation.

I've done again some tests. Connected to my ATM card, I've a ATM switch which sends
ATM traffic (Ethernet Bridge PVC 0/40), the nas0 is also bound to the pvc 0/40 
(br2684ctl -b -c 0 -a 0.0.40). The nas0 interface doesn't receive traffic (RX=0 and 
tcpdump -n -i nas0 -> 0 packet). 

I've also tried again the brctl command. I added eth0 and nas0 in br0, and when
br0 becomes up, the Eth0 traffic is bridged to nas0 == the computer is crashed. 

If you have some explanations...
thanks.
