VPLS LDP
Displaying the VPLS peer FSM state with LDP support
The user can display the various VPLS peer FSM states with the LDP integration on the device using
the show mpls vpls commands.
provides a description of all the peer FSM states with the LDP support.
TABLE 80
PEER FSM state description
Peer FSM state name
State description
Wait for functional local ports
No functional local endpoints.
Wait for LSP tunnel to Peer
No LSP tunnels available to reach the remote peer.
Wait for PW UP (Wait for LDP Session)
LDP session to remote peer is down.
Wait for PW UP (Wait for remote VC label)
PW is down (waiting for remote peer's VC label.)
Wait for PW UP (VC type Mismatched)
PW is down (VC type mismatched).
Wait for PW UP (MTU Mismatched)
PW is down (MTU mismatched).
Wait for PW UP (VC Bind In Progress)
PW is down (Local VC binding in progress).
Operational
PW is up and operational.
Wait Withdraw Done …
Waiting for VC withdraw completion (internal intermediate states).
VC BIND Failure State
VC binding failed. User intervention required.
VC Withdraw Failure State
VC withdraw failed. User intervention required.
User intervention is required to recover from the VC Bind Failure state, and the VC Withdraw Failure
state. To recover, the user must delete the failed peer and then add it back. These failure states
may occur during extreme conditions when the system runs out of memory to issue ITC requests.
When these failures are detected, VPLS generates the following syslog messages accordingly.
WARN: VPLS id X Peer IP Address: aa.bb.cc is placed in VC Bind Failure state due
to low system memory.
WARN: VPLS id Y Peer IP Address: dd.ee.ff is placed in VC Withdraw Failure state
due to low system memory.
VC type mismatched
The following example shows the output for the LDP integration for a VC type mismatched case.
