no route interface

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 keywords added in JUNOSe Release 9.1.0.

Description

Routes layer 2 traffic on a specified MPLS tunnel. 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. You cannot enter the command in a VRF. The no version negates this command. See also the mpls-relay command.

Options

lspName—Name of the MPLS LSP
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
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 not to 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.
