We have 3 switches connected with each other and formed a ring topology.
When i try to make l2 point-to-point tunnel , one of my edge switch (where i try to up dot1q trunk and udld port) can view another one ( udld protocol up for few second and cdp say name of the neighbor) but this "another one" can't see anything!
But in same time ordinary l2 tunnel (not point-to-point) work fine.
Tunneling is not supported on trunk ports. If you enter the l2protocol-tunnel interface configuration command on a trunk port, the command is accepted, but Layer 2 tunneling does not take affect unless you change the port to a tunnel port or access port.
