Release Information
Command introduced in JUNOSe Release 8.0.0.
Description
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).
Options
■
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
