Release Information

Command introduced before JUNOS Release 7.4.

Description

(T Series and M Series routers, except for the M160 router) Display virtual private LAN service (VPLS) connection information.

Options

none — Display information about all VPLS connections for all routing instances on all logical systems.

brief | extensive — (Optional) Display the specified level of output.

down | up | up-down — (Optional) Display nonoperational, operational, or both types of connections.

history — (Optional) Display information about connection history.

instance instance-name — (Optional) Display the VPLS connections for the specified routing instance only.

local-site local-site-name — (Optional) Display the VPLS connections for the specified local site name or ID only.

remote-site remote-site-name — (Optional) Display the VPLS connections for the specified remote site name or ID only.

logical-system (all | logical-system-name) — (Optional) Perform this operation on all logical systems or on a particular logical system.

status — (Optional) Display information about the connection and interface status.

summary — (Optional) Display summary of all VPLS connections information.

Output Fields

Table 194 lists the output fields for the show vpls connections command. Output fields are listed in the approximate order in which they appear.

Table 194: show vpls connections Output Fields

Field Name

Field Description

Instance

Name of the VPLS instance.

Local site

Name of the local site.

Local interface

Name of the local VPLS virtual loopback tunnel interface or label switched interface. Virtual loopback tunnel interfaces are displayed using the vt-fpc/pic/port.nnnnnformat.Label switched interfaces are displayed using the lsi.nnnnn format. In both cases, nnnnn is a dynamically generated virtual port used to transport and receive packets from other provider edge (PE) routers in the VPLS domain.

Label-base

First label in a block of labels. A remote PE router uses this first label when sending traffic toward the advertising PE router.

Offset

Displays the VPLS Edge (VE) block offset in the Layer 2 VPN NLRI. The VE block offset is used to identify a label block from which a particular label value is selected to setup a pseduowire for a remote site. The block offset value itself indicates the starting VE ID that maps to the label base contained in the VPLS NLRI advertisement.

Size

Label block size.

Range

Label block range.

Preference

Preference value advertised for a VPLS site. When multiple PE routers are assigned the same VE ID for multi-homing, you might need to specify that a particular PE router acts as the designated forwarder by configuring the site preference value. The site preference indicates the degree of preference for a particular customer site. The site preference is one of the tie-breaking criteria used in a designated forwarder election.

status-vector

Bit vector advertising the state of local PE-CE circuits to remote PE routers. A bit value of 0 indicates that the local circuit and LSP tunnel to the remote PE router are up, whereas a value of 1 indicates either one or both are down.

connection-site

Name of the connection site.

Type

Type of connection: loc (local) or rmt (remote).

St

Status of the connection. (For a list of possible values, see the Legend for connection status (St) field.)

Time last up

Time connection was last in the Up condition.

# Up trans

Number of transitions from Down to Up condition.

Status

Status of the (local or remote circuit) local interface:

  • Up—Operational
  • Dn—Down
  • NP—Not present
  • DS—Disabled
  • WE—Wrong encapsulation
  • UN—Uninitialized

Encapsulation

Type of encapsulation: VPLS.

Remote PE

Address of the remote provider edge router.

Negotiated control-word

Whether a control word has been negotiated: Yes or No.

Incoming label

Name of the incoming label.

Outgoing label

Name of the outgoing label.

Time

Date and time of VPLS connection event.

Event

Type of event.

Interface/Lbl/PE

Interface, label, or PE router.
