prefixes.

Parameters
-a source-ip: Specifies the source address for the MPLS echo request packets to be sent. If you do
not specify this option, the primary IP address of the outgoing interface is the source address of the
MPLS echo requests.
-exp exp-value: Specifies the EXP value for echo request packets. The value range is 0 to 7, and the
default is 0.
-h ttl-value: Specifies the maximum TTL value for MPLS echo request packets, namely, the
maximum number of hops to be inspected. The value range for the ttl-value argument is 1 to 255,
and the default is 30.
-r reply-mode: Specifies the reply mode of the receiver in response to MPLS echo request packets.
The reply-mode argument can be 1 or 2, where 1 means "Do not reply" and 2 means "Reply by
using a UDP packet." The default is 2.
-t time-out: Specifies the timeout interval for the reply to an MPLS echo request. The value range is
0 to 65535 milliseconds, and the default is 2000 milliseconds.
ipv4 dest-addr mask-length: Specifies an FEC by an IPv4 destination address and the mask length.
The value range for the mask-length argument is 0 to 32.
destination destination-ip-addr-header: Specifies the destination address in the IP header of an
MPLS echo request. The destination address must be an address on subnet 127.0.0.0/8—any local
loopback address.

node.
