After LSP discovery, MPLS Manager monitors the TE LSPs and LDP LSPs that are built on Cisco or Juniper M/T devices. It also monitors the subLSPs that are built on Juniper M/T devices.
If MPLS Manager detects that LSP rerouting has occurred (applicable to TE LSPs only), it initiates rediscovery of the rerouted LSP. LSP monitoring and rediscovery are controlled by the LSP polling group in the Polling and Thresholds Console, as explained in the MPLS Manager Configuration Guide.
