Command introduced in JunosE Release 8.0.0.
Sends an MPLS echo request packet to the specified layer 2 cross-connect virtual (Martini)
circuit or, alternatively, sends MPLS echo packets to the egress node in a
point-to-multipoint LSP. There is no no version.
The echo request packet generated by this command contains the FEC 128 Pseudowire
(Current) sub-TLV described in RFC 4379—Detecting Multi-Protocol Label Switched
(MPLS) Data Plane Failures (February 2006).
NOTE: This command is not supported for local cross-connects because
local cross-connects do not employ an LSP.
The MPLS echo request packets and echo reply packets created by this command to
detect connectivity to egress nodes in point-to-multipoint LSPs use the P2MP Responder
Identifier TLV described in the IETF draft, Detecting Data Plane Failures in
Point-to-Multipoint Multiprotocol Label Switching (MPLS) - Extensions to LSP
Ping—draft-ietf-mpls-p2mp-lsp-ping-08.txt (February 2010 expiration).
vrfName—Name of the VRF context; when you specify a VRF name, the ping is generated
from the specified VRF—for that reason the MPLS shim interface must exist in the VRF
interfaceType—Interface type; see Interface Types and Specifiers on page 5
interfaceSpecifier—Particular interface; format varies according to interface type; see
Interface Types and Specifiers on page 5
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
