===============================================================================
A trap is also generated:
70002 2013/07/17 16:06:59.46 PST MINOR: LDP #2008 Base LDP Session State Change "Session
state is operational. Overload Notification message is sent to/from peer 110.20.1.1:0
with overload state true for fec type prefixes"
Step 2
Besides interfaces and targeted peer, locally originated FECs may also be put into overload. These
are the following:
- unicast fec-originate pop
- multicast local static p2mp-fec type=1 [on leaf LSR]
- multicast local Dynamic p2mp-fec type=3 [on leaf LSR]
The user can check if only remote and/or local FECs have been set in overload by the resource
enhanced resource exhaustion mechanism using the following command:
- [tools dump router ldp instance]
