Description (partial)


When doing software downgrade from 721 to 712, we see ldp sessions are going down. This happens after system boots in 712 release. Note that 721 configs are also present while doing downgrade.

After upgrade is successful to 721 release, upgrading the IMFPGA to 5.0.1 and then downgrading the system to 7.1.2 results in this issue as the recommended IMFPGA version is 3.04.
