Ahh ok .. this is "OSPF virtual link" not an emulated "virtual link" seen as p2p to any routing protocol. Thx, R. On Fri, Feb 4, 2022 at 7:14 PM Acee Lindem (acee) wrote: > Hi Robert, > > There is no tunnel for an OSPF virtual link, the transit area will require > leaking of backbone routes

Hi Robert, There is no tunnel for an OSPF virtual link, the transit area will require leaking of backbone routes without summarization. Also note that the virtual link endpoint could be reachable in the transit area but may not be up. Multi-hop BFD would still be useful for a virtual link.

Muthu, If you are using virtual link why is this still multihop BFD ? Thx, R. On Fri, Feb 4, 2022 at 6:22 PM Muthu Arul Mozhi Perumal < muthu.a...@gmail.com> wrote: > Hi Ketan, > > Sure, looking forward to the clarification in the draft on multi-hop BFD.. > > Just curious, are there

Hi Ketan, Sure, looking forward to the clarification in the draft on multi-hop BFD.. Just curious, are there interoperable implementations for OSPF multi-hop BFD strict mode for virtual links or p2p unnumbered interfaces? Regards, Muthu On Fri, Feb 4, 2022 at 5:36 PM Ketan Talaulikar wrote:

Hi Muthu, When we say a "link" here, it is in the context of the OSPF interface and neighbor FSM. My understanding is that this term includes virtual links as well. As such, we can add some text in the introduction section to clarify the same and also put a reference to RFC5883 for BFD multi-hop
