Diagnostic Tools Overview
Purpose
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.
Checks the operability of the
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.
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.
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.
The Services Router does not test the
connection between a PE router and
a customer edge (CE) router.

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