The Wait for LDP session to Peer state is no longer displayed in the output of the show mpls vpls
detail command. The Wait for Pseudo Wire (PW) Up (Wait for LDP session to Peer) state is now
displayed, and replaces the existing state. The total VC labels allocated field is also removed from
the output. In the following example, the LDP session to the remote peer is down. The Local VC lbl
field displays N/A (not applicable).

The maximum number of VC labels available for VPLS instances is equal to 64K. When configuring
a new VPLS peer, the total number of VPLS peers exceeds 64K, and causes the configuration to be
rejected. The following error message is displayed on the console.
Brocade(config-mpls-vpls-1)# vpls-peer 10.23.23.23
Error - Unable to create vpls peer 10.23.23.23 for VPLS 1 due to no VC label
resource.
The Wait for PW Up (No label Resource) state is introduced in the output of the show mpls vpls
detail command. In the following example, the Wait for PW Up (No label Resource) state is
highlighted.

When the system runs out of memory, a warning message is displayed on the console. To recover
from this state, the user is required to delete the failed peer and reconfigure it. VPLS generates the
following warning messages.
