Chapter 13: M Commands
default preference is determined by the interface stack on which the MPLS interface
is stacked.
sequencing—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; 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.
no-sequencing—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.
relay-format ethernet—Specifies that the router uses Ethernet signaling and
encapsulation, which causes the VLAN interface to appear as an Ethernet interface to
the other side of the connection; enables a VLAN interface on one side of an MPLS
tunnel to communicate with an Ethernet or a bridged Ethernet interface on the other
side of an MPLS tunnel. The VLAN tag is not included in the MPLS encapsulation. This
option is not available on serial or POS interfaces for HDLC layer 2 circuits. It is available
only on VLAN interfaces
relay-format frame-relay—Specifies that the router uses legacy (pre-RFC 4619) Frame
Relay pseudowire type value for signaling and encapsulation. Enables a router running
JunosE Software that supports the pseudowire type value defined in RFC 4619,
Encapsulation methods for transport of Frame Relay over MPLS Networks, to
interoperate with a router that uses the legacy (pre-RFC 4619) pseudowire type value.
This option is available on serial or POS interfaces for Frame Relay layer 2 circuits. It
is not supported on E120 and E320 routers.
relay-format ppp—Specifies that the router uses VC-type PPP signaling and PPP
encapsulation instead of VC-type HDLC signaling and HDLC encapsulation. The router
uses VC-type HDLC signaling and HDLC encapsulation by default. This option is
available only on serial and POS interfaces for HDLC layer 2 circuits.
relay-format vlan—Specifies that the router uses VLAN signaling and encapsulation.
This option is not available on serial or POS interfaces for HDLC layer 2 circuits. It is
available for VLAN interfaces.
relay-format ethernet-raw-mode—Specifies that the router uses Ethernet raw mode
encapsulation for packets entering and leaving pseudowires. This service corresponds
to PW type 0x0005 "Ethernet" [IANA]. When configured on an S-VLAN subinterface,
enables the provider edge (PE) device to strip the S-VLAN tags from all packets entering
the Martini circuit (MPLS packet switched network). It is supported on ES2 4G, ES2
10G, and ES2 10G Uplink LMs on E120 and E320 routers. You can enable the raw mode
configuration only for MPLS shim interfaces stacked on SVLAN interfaces.
