No RLQ's with backbonefast?

Dilbert65

I have 2 2950's that are trunking on 2 ports. I configured backbonefast on both server. The root switch is the vtp server ad the other is setup as the client with the same domain names. Other than that the default settings.

Root Switch:
S2#show spanning-tree summ total
Switch is in pvst mode
Root bridge for: VLAN0001
EtherChannel misconfig guard is enabled
Extended system ID is enabled
Portfast Default is disabled
PortFast BPDU Guard Default is disabled
Portfast BPDU Filter Default is disabled
Loopguard Default is disabled
UplinkFast is disabled
BackboneFast is enabled
Pathcost method used is short
Name Blocking Listening Learning Forwarding STP Active

My question is shouldn't there be RLQ traffic?

Thanks for any input

Good question though. From my understanding, the RLQ Request is only sent out IF an inferior BPDU is received. Check out the doc below, the image at the "Reacting to Indirect Link Failures" section shows when it sends a RLQ.
