[ detail ]
Command introduced in JunosE Release 8.0.0.
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).
vrfName—Name of the VRF context
targetAddress—IP address of the target VPN network
targetMask—Netmask for the target address
targetIpv6Prefix—IPv6 prefix for the target VPN network
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
repeat—Specifies that multiple ping packets are sent
