• These two commands *DO NOT* Clear the overload state for the local FECs.
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:
