Additional Information Purpose ping mpls Command J-Web Ping MPLS
Tool
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.
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. ping mpls ldp Ping LDP-signaled LSP
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 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. ping mpls l3vpn Ping LSP to Layer 3
VPN prefix
For information about interface
names, See the interface naming
conventions in the J-series Services
Router Basic LAN and WAN Access
Configuration Guide. Checks the operability of the
connections related to a Layer 2 VPN.
The Services Router directs outgoing
request probes out the specified
interface. ping mpls l2vpn
interface
Locate LSP using
interface name
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. ping mpls l2vpn
instance
Instance to which this
connection belongs
Checks the operability of the Layer 2
circuit connections. The Services
Router directs outgoing request
probes out the specified interface. ping mpls l2circuit
interface
Locate LSP from
interface name
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. ping mpls l2circuit
virtual-circuit
Locate LSP from virtual
circuit information
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. ping mpls lsp-end-point Ping end point of LSP
