Release Information
Command introduced in JUNOSe Release 8.0.0.
Description
Sends an MPLS echo request packet to the specified L3VPN IP or IPv6 prefix, 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 either the VPN IPv4
sub-TLV or VPN IPv6 sub-TLV described in RFC 4379—Detecting Multi-Protocol Label
Switched (MPLS) Data Plane Failures (February 2006). Which sub-TLV is included
depends on whether the ping is intended for an IPv4 prefix or an IPv6 prefix.
You can use this command to send a request to a VPNv4 prefix in the specified VRF.
If you do not specify a VRF, then you must issue the command from the VRF context.
In any case, the ping originates from the parent router.
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).
