Release Information
Command introduced before JUNOSe Release
7.1.0.
control-word, no-control-word, no-sequencing, and vlan keywords added in JUNOSe Release
7.1.0.
frame-relay keyword
added in JUNOSe Release 9.1.0.
ethernet-raw-mode keyword added in JUNOSe Release 10.0.0.
Description
Routes layer 2 traffic to the specified router
by creating an MPLS shim interface on the layer 2 interface. The router
can use any MPLS LSP to the remote destination address that you specify.
You must issue this command in the virtual router where the remote
address can be reached; that is, in the virtual router providing core
connections. The no version removes the
shim interface. See also the route interface command.
Options
-
remoteIpAddress—IP address
of the router on the remote end of the layer 2 circuit
-
vcidValue—Integer in the range
1–4294967295 that identifies the virtual connection; the two
ends across the MPLS core must match inside each VC type
 |
Note:
The VLAN ID, DLCI, or ATM VPI/VCI are not related to the
VC ID and can be different on each end of the connection.
|
-
groupIdValue—Integer in the
range 0–4294967295 that identifies a group of virtual connections;
not currently used
- control-word—Indicates that the local preference
is to 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.
- 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.
