On our MX480's, we've known for a very long time that IPv4 BFD is
supported in the PFE. However, IPv6 BFD runs on the RE.

Last year, we got an ER submitted with Juniper to fix this as we believe
IPv4 and IPv6 parity is crucial to IPv6's success. I sent a a reminder a
month ago, haven't heard back. Let me ping my SE.
