# l2vpn sequencing

#### Syntax

[ no | default ] l2vpn l2VpnName sequencing

#### Release Information

Command introduced in JUNOSe Release 8.1.0.

#### Description

Specifies that the local preference is to include nonzero sequence numbers with the control word, enabling the remote PE to detect out-of-order packets. This command has no effect if no control word is sent in the packets. The router always accepts zero sequence numbers and checks the order of nonzero sequence numbers of MPLS packets received from the remote PE. Any out of order packets are dropped, regardless of whether sequencing is configured. The no version specifies that the sequencing number in the control word is set to zero, instructing the remote PE router to not attempt to detect out-of-order packets; has no effect if no control word is sent in the packets. The default version accepts the preference determined by the interface stack on which the MPLS shim interface is stacked.
