Enhanced Resource Handling Procedures

Step 1
If the peer AND the local LSR do support the Overload Protection Capability it means that the
LSR will signal the overload state for the FEC type which caused the resource exhaustion as part
of the enhanced resource handling mechanism.
In order to verify if the local router has received or sent the overload status TLV, perform the
following:
- [show router ldp session detail]
show router ldp session 110.20.1.1 detail
-------------------------------------------------------------------------------
Session with Peer 110.20.1.1:0, Local 110.20.1.110:0
