Ta b l e 106 show mpls l2transport vc detail Field Descriptions
Field Description
Local interface Interface on the local router that has been enabled to send and receive
La
yer 2 packets. The interface varies, depending on the transport type. The
o
utput also shows the status of the interface.
line protocol Status of the line protocol on the edge-facing interface.
Destination address IP address of the remote router specified for this VC. You specify the
des
tination IP address as part of the mpls l2transport route command.
VC ID Virtual circuit identifier assigned to the interface on the router.
VC status Status of the VC, which is one of the following:
• Admin down—The VC has been disabled by a user.
• Down—The VC is not ready to carry traffic between the two VC
endpoints.
• up—The VC is in a state where it can carry traffic between the two VC
endpoints. A VC is up when both imposition and disposition interfaces
are programmed.
– The disposition interface is programmed if the VC has been
configured and the client interface is up.
– The imposition interface is programmed if the disposition interface
is programmed and a remote VC label and an IGP label exist. The
IGP label can be an implicit null in a back-to-back configuration.
(An IGP label means there is an LSP to the peer.)
Output interface Interface on the remote router that has been enabled to transmit and receive
La
yer 2 packets.
imposed label stack Summary of the MPLS label stack used to direct the VC to the PE router.
Preferred path Path that was assigned to the VC and the status of that path. The path can
b
e a Multiprotocol Label Switching (MPLS) traffic engineering tunnel or an
IP address or hostname of a peer PE router.
Default path Status of the default path, which can be disabled or active.
By default, if the preferred path fails, the router uses the default path.
H
owever, you can disable the router from using the default path when the
preferred path fails by specifying the disable-fallback keyword with the
preferred-path command.
