Table 1. Resolved Issues, Platform-Specific, and Feature Change Requests (CRs) in ExtremeXOS 16.2.2
CR Number Description
xos0065519 Loops may occur in network after the performing the following specific sequence:
  1. Enable STP in any VLAN with specific set of ports.
  2. Delete all ports from that VLAN.
  3. Add same set of ports to another VLAN.
  4. Enable EAPS/ESRP/STP protocol on this new VLAN.
xos0052432 Need provision for advertising/receiving unique local IPv6 unicast address (ULA) using BGP protocol.

While configuring STP (802.1d) with port-encapsulation mode as EMISTP where the L2PT-enabled VMAN and access VLAN have the same tag, the designated bridge is not accepting the L2PT tunneled BPDUs from the root bridge, and thus causes a loop (designated bridge also becomes a root bridge).

This problem does not occur:

  • When the access VLAN's tag and the L2PT-enabled VMAN‘s tag are different.
  • Without any L2PT configured, with the same tag used for the access VLAN and provider-edge VMAN.
  • When using Per-VLAN Spanning Tree Plus (PVST+), regardless of same or different tags.
