■
no-control-word—Indicates that the local preference is to not use the control
word for the layer 2 packets encapsulated in MPLS packets sent to the remote
PE router. The 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.
