Description (partial)

PDU size was reduced to 1000 bytes in XRv 5.1, which causes JUNOS to send a fatal error notification message with status data "bad PDU length". The TCP session is then closed.

This will happen as soon as you try to establish an LDP session between XRv 5.1 and JUNOS. XRv 4.3.2 is not affected by this issue. This issue only affects ENXR and XRv.
