Command introduced in JunosE Release 8.0.0.
data-size keyword and dataSize variable added in JunosE Release 11.1.0.
Sends MPLS echo request packets with successively higher TTL values to the specified
VPLS instance. Discovers the path MPLS packets follow to the destination. There is no
no version.
The MPLS echo request packets and echo reply packets created by this command use
the L2 endpoint sub-TLV described in RFC 4379—Detecting Multi-Protocol Label Switched
(MPLS) Data Plane Failures (February 2006).
vrfName—Name of the VRF context from which to generate the ping
vplsName—Name of a VPLS instance created with the bridge vpls
transport-virtual-router command
senderSiteId—Numerical identifier for the site sending the MPLS echo request packet;
must be an unsigned 16-bit integer greater than zero that is unique across the VPLS
domain
remoteSiteId—Numerical identifier for the site receiving the MPLS echo request packet;
must be an unsigned 16-bit integer greater than zero that is unique across the VPLS
domain
dataSize—Size of the LSP ping message (does not include the UDP, IP, and MPLS
headers of the packet); in the range 0–6400 bytes. The default value is 100 bytes. You
can use this option to enable the pad TLV to be added to the MPLS LSP ping message
(echo request), which results in the future MPLS LSP ping echo requests to be of the
same specified number of bytes.
startIpAddress—First IP address within the 127.0.0.0/8 destination range
endIpAddress—Last IP address within the 127.0.0.0/8 destination range
increment—Number in the range 0–255 that specifies the increment between addresses
in the destination address range
sourceAddr—IP address used as the packet source address
