Sir,
In draft-ietf-bfd-base-04.txt Sec 6.3 (Page 18), It is
mentioned that " Once the remote end echoes back the
local administrator, all further received packets are
demultiplexed based on the Your duscriminator field
only(which means that, among other things , the source
address field can change, or the interface over which
the packets are recived can change, but the packets
will still be associated with proper session.)"

Does this mean that Suppose we have two routers RT1
and RT2.

A session is established between Rt1 and Rt2 at I1
interface.My Discriminator for RT1 At I1 is X. My
Discriminator for Rt2 is Y at Interface I1.and session
state for Rt2 is init.Now, If I send a packet at I2
interface of RT1 with Your Discriminator as
Y(My.Discriminator of Rt2 at I1) and My. Discriminator
= X , then Rt2 will send a BFD Packet with session
state 3 at Interface I1.

With Regards,
Murti
