Hi authors,
I have one question about BFD packet encapsulation: you point out 2 ways: by GAL/G-ACH, or by IP. And you think that the way by IP is not suitable because BFD packets will follow a different path than that of data packets when they use different destination IP address.
Can you clarify the specific reason? And why can the way by GAL/G-ACH avoid this problem of different path?
Thanks!

B.R.
Frank
