Feature Limitations

  • Table 17-10 lists the specification of SEP.

    Table 17-10  Specification of SEP
    Item Specification

    Maximum number of segments on the device


  • On a SEP network where there are no-neighbor edge interfaces, a device that is not in a SEP segment cannot be added to the control VLAN of the SEP segment. Otherwise, a loop will occur on the network.

  • If both SEP and VLL are deployed on the network and the SEP segment ID configured on the PE is different from that configured on the CE, SEP protocol packets sent by the CE cannot traverse VLL tunnels. Therefore, SEP cannot be used to connect o VLL networks through the closed ring topology.
