Release Information
Command introduced in JUNOSe Release 8.0.0.
Description
Sends an MPLS echo request packet to the specified IP or IPv6 address or,
alternatively, sends MPLS echo packets to the egress node in a point-to-multipoint
LSP. There is no
no version.
The MPLS echo request packets and echo reply packets created by this command
use the LDP IPv4 LSP sub-TLV described in RFC 4379—Detecting Multi-Protocol Label
Switched (MPLS) Data Plane Failures (February 2006).
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 LSP to
the specified prefix must originate from the VRF because the ping is generated
from the specified VRF
■
targetIpAddress —IP address of the ping target
■
targetIpv4Mask —Network mask for target IP address
■
targetIpv6Prefix —IPv6 address of the ping target
■
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
■
packetCount —Number of packets to send to the destination address, in the range
0–4294967295; default value is 5; 0 means ping forever
■
ttlValue —Hop count specified by setting the time-to-live field in the header, in
the range 1–255; default value is 32
