Table 107: Options for Checking MPLS Connections (continued)

J-Web Ping MPLS	ping mpls Command	Purpose
Tool
Ping LDP-signaled LSP	ping mpls ldp	Checks the operability of an LSP that
		has been set up by the Label
		Distribution Protocol (LDP). The
		Services Router pings a particular LSP
		using the forwarding equivalence
		class (FEC) prefix and length.

Additional Information

When an LDP-signaled LSP has several gateways, the Services Router sends the ping requests through the first gateway.

Ping requests sent to LDP-signaled LSPs use only the master routing instance.

Ping LSP to Layer 3	ping mpls l3vpn	Checks the operability of the
VPN prefix		connections related to a Layer 3 VPN.
		The Services Router tests whether a
		prefix is present in a provider edge
		(PE) router's VPN routing and
		forwarding (VRF) table, by means of
		a Layer 3 VPN destination prefix.

The Services Router does not test the connection between a PE router and a customer edge (CE) router.

Checks the operability of the connections related to a Layer 2 VPN. The Services Router directs outgoing request probes out the specified interface.

Checks the operability of the connections related to a Layer 2 VPN. The Services Router pings on a combination of the Layer 2 VPN routing instance name, the local site identifier, and the remote site identifier, to test the integrity of the Layer 2 VPN circuit (specified by the identifiers) between the inbound and outbound PE routers.

Checks the operability of the Layer 2 circuit connections. The Services Router directs outgoing request probes out the specified interface.

Checks the operability of the Layer 2 circuit connections. The Services Router pings on a combination of the IPv4 prefix and the virtual circuit identifier on the outbound PE router, testing the integrity of the Layer 2 circuit between the inbound and outbound PE routers.

Checks the operability of an LSP endpoint. The Services Router pings an LSP endpoint using either an LDP FEC prefix or an RSVP LSP endpoint address.

For information about interface names, See the interface naming conventions in the J-series Services Router Basic LAN and WAN Access Configuration Guide.
