hi,

I have query regarding BFD packet flow when LSP Ping is used for bootstrapp=
ing.=20

As per my understanding from the RFC 5880 and RFC 5884 when LSP Ping is use=
d for bootstrapping the remote end MUST reply with BFD control in response =
to the LSPPing.

The specification does not clearly specify about the Stat parameter value t=
hat should be returned in the response of LSPPing. Should it have the value=
 Init or Down? Or it might be possible to return no stat information.

Can someone please share the exact packet flow that happens during BFD sess=
ion set up with LSPPing in Bootstrap till the session comes into UP state?

thanks a lot in advance for ur help,
rakesh
