[j-nsp] l2pt issues

[snort bsd]

 hello, experts:


i am trying to get following topology (l2pt) to work; basically i am trying to get l2pt (layer-2 protocol tunneling) to tunnel lacp frames:

ex4200-1(ae0, lacp) <----> ex4200-2(l2pt, pe) ---- ex4200-3 ---- ex4200-4(l2tp, pe) <----> (ae0, lacp) ex4200-5

from the perspective of the design, it is simple, but the ex4200-2 just doesn't seem to encapsulate the lacp frames (from ex4200-1). what i expect to see ex4200-2 received lacp frames from ex4200-1 and deliver them to ex4200-3 with destination mac address 01:00:0c:cd:cd:d0 (GBPT mac address), but it is not happening.


here are the configurations:

1) ex4200-1

ae0 {
      aggregated-ether-options {
             minimum-links 1;
             link-speed 1g;
             lacp {
                     active;
                     periodic fast;
             }
     }
     unit 0 {
             family ethernet-switching {
                     port-mode trunk;
                     vlan {
                             members vlan_101;
                     }
            }
     }
}

ethernet-switching-options {
      dot1q-tunneling {
              ether-type 0x8100;
      }
}

vlans {
       vlan_10 {
                vlan-id 10;
                dot1q-tunneling;
      }
}


2) ex4200-2

ae0 {
      aggregated-ether-options {
              minimum-links 1;
              link-speed 1g;
      }
      unit 0 {
              family ethernet-switching {
                       port-mode trunk;
                       vlan {
                                members vlan_10;
                       }
             }
      }
}
ae1 {
      aggregated-ether-options {
             link-speed 1g;
      }
      unit 0 {
              family ethernet-switching {
                      port-mode trunk;
                      vlan {
                               members all;
                      }                           
              }
       }
}


ethernet-switching-options {
      dot1q-tunneling {
              ether-type 0x8100;
      }
} 

vlans {
        vlan_100{
                vlan-id 100;
                dot1q-tunneling {               
                        customer-vlans 1-20;
                        layer2-protocol-tunneling {
                                 all;
                        }
                }
        }
}


-- i tried ether-type 0x88a8 and it made no difference.
-- the code is 11.4R5.5.


thanks for help.
