ping vpls instance

Syntax

Release Information

Command introduced in JUNOS Release 9.1.

Description

Check the operability of virtual private LAN service (VPLS) connections. Type Ctrl+c to interrupt a ping vpls instance command.

When you issue a ping vpls instance command, a chassis MAC address is drawn from the ingress PE router's pool of MAC addresses and used to create the VPLS ping packet. The ping packet is then forwarded to the egress PE router. When the egress PE router receives the ping packet, it learns the MAC address from the VPLS ping packet. The MAC address is added to the egress PE router's MAC table.

The ping vpls instance command relies on the LSP ping and trace infrastructure defined in RFC 4379, Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures and further enhancements defined in Internet draft draft-stokes-vkompella-ppvpn-hvpls-oam-02, Testing Hierarchical Virtual Private LAN Services.

Options

instance instance-name — Specify the name of the VPLS routing instance.
