Re: How are you configuring BFD timers?

No sure if this link has been provided yet, but this is how I learned BFD - https://supportforums.cisco.com/t5/service-providers-documents/bfd-support-on-cisco-asr9000/ta-p/3153191 My only experience with BFD has been with short paths using grey optics and interstate DWDM spans. I found 3x50ms ec

Re: Juniper MX - Routed pseudowire using LDP - VPWS or VPLS

I do see one benefit to using the stitched LT VPWS solution - MAC learning. On the VPWS solution, your PE devices are not learning the MAC addresses. I also noticed that Juniper is a bit strange with VPLS attached to the IRB in that you never see the IRB MAC in the VPLS instance. But I think thi

COX BGP contact

I know there should be a more reasonable way to do this. If someone has responsibility for COX BGP (AS 22773) would love to hear from you. Multiple days of getting the run around in various NOCs has lead to nowhere. Thanks in advance, Deepak

Looking for someone from Intuit to contact me.

I have a few users on my cloud that are not able to reach intuit.com or quickbooks.intuit.com. In addition my users are not able to eFile taxes from their terminal server with Quickbooks on it. We have checked and our firewalls are not blocking.

Re: How are you configuring BFD timers?

Thanks to everyone who has responded so far. Enlightening! My understanding around the origins of BFD is that it was developed in part to try and bring SONET like switchover times to an Ethernet world. What I’m reading is for those who do run BFD, no one seems to be dialing it down to try and

Re: How are you configuring BFD timers?

RFI is corollary to LOS. Both are essentially speed of light limited, there in no uncertainty or detection margin. After one side sees LOS other side will see RFI, if it's not seeing LOS as well. I personally would consider BFD for: radio, pseudowire, L2 switch and equivalent poorly failing links

Re: How are you configuring BFD timers?

Why does DWDM imply need of BFD? DWDM has no problem propagating loss-of-signal and asserting remote failure. It is of course possible to configure DWDM so that this does not happen, particularly if you buy protected circuit you might not want it to happen. But as per usual, you should test that
