BFD with MPLS Provider

 

We have MPLS circuit that flap last week, as appear in the logs, BGP was down because we lost BFD. I have also and IP SLA that doesn't showed any issue and was UP all the time.

Yesterday I ran a packet capture in the router interface that connect with the provider, and I notice that we are crossing only BFD Control packet,  no bfd-echo packet.

Does turning off the BFD echo function have a negative impact on the BGP failure detection ? Will BGP up if we are only crossing BFD Control ?

 

Looking in the packet, from the provider we are receiving Required Min Echo Interval: 0 ms (0 us)

But we are sending Required Min Echo Interval: 300 ms (300000 us)
