Hi,<br> I am trying to write down the very basic version of TRILL in
linux. TRILL is a protocol which encapsulates the entire packet
including ethernet header to forward it to end nodes without the danger
of temporary loops. Then it is decapsulated at the bridge having the end
host for which the packet is being destined. <br>
I have written a sample module which encapsulates the entire packet with
TRILL header over that a new ethernet header. The ether_type of TRILL
is 0x88c8. I have put it in ether_type of mac_header. when i ping from
one machine to another one, the bridging module having TRILL hooks,
encapsulates the packets and send them to forwarding function
(br_forward) in bridge. I am not recalculating the checksum. I receive
the packets on other bridge but hook in br_handle_frame function to
decapsulate the TRILL encapsulated traffic. I use a check of ether_type
== ETHERTYPE_TRILL before calling decapsulating function. But it does
not enter into the check to call the decapsulating function. <br>
<br>I don't know what is going wrong with it. any idea and help regarding this problem?<br><br>Thanks in advance...!<br><br>Regards,<br>Syed M. Mohsin Kazmi
