When at least one local FEC has been set in overload the following trap will occur:
69999 2013/07/17 16:06:59.21 PST MINOR: LDP #2002 Base LDP Resources Exhausted "Instance
state changed - vRtrID: 1, administrative state: inService, operational state: inService"
Step 3
After the user has detected that at least one overload status TLV has been sent or received by the
LSR, he/she must protect the router by applying one or more of the following to free resources up:
•
•
Step 4
Next, the user has to manually attempt to clear the overload state on the affected sessions and for
the affected FEC types and allow the router to clear the overload status TLV to its peers.
Please note that due to the dynamic nature of FEC distribution and resolution by LSR nodes, one
cannot predict exactly which sessions and which FECs will be cleared after performing the
following commands if the LSR activates overload again.
One of the following commands can be used depending if the user wants to clear all sessions or at
once or one session at a time:
- [clear router ldp resource-failures]

Identify the source for the [unicast/multicast/service] FEC flooding. This is most likely
the LSRs which session received the overload status TLV.
Configure the appropriate [import/export] policies and/or delete the excess
multicast/service] FECs from the FEC type in overload.
Clears the overload state for the affected sessions and FEC types.
