Base Resource Handling Procedures
load
{...... snip......}
When at least one local FEC has been set in overload the following trap will occur:
23 2013/07/17 15:35:47.84 PST MINOR: LDP #2002 Base LDP Resources Exhausted "Instance state
changed - vRtrID: 1, administrative state: inService, operationa l state: inService"
Step 3
After the user has detected that at least, one link LDP or T-LDP adjacency has been brought down
by the resource exhaustion mechanism, 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 (no resource) state and allow the
router to attempt to restore the link and targeted sessions to its peer.
Please note that due to the dynamic nature of FEC distribution and resolution by LSR nodes, one
cannot predict exactly which FECs and which interfaces or targeted peers will be restored after
performing the following commands if the LSR activates resource exhaustion again.
One of the following commands can be used:
- [clear router ldp resource-failures]
•
•
- [clear router ldp interface ifName]
- [clear router ldp peer peerAddress]
•
