The JUNOS software has the following exceptions:
- A packet with a sequence number of 0 is treated as out of sequence.
- Any packet which does not have the next incremental sequence number is considered out of sequence.
- When out-of-sequence packets arrive, the expected sequence number for the neighbor is set to the sequence number in the Layer 2 circuit control word.
