R0106-HP MSR Router Series MPLS Command Reference(V7)

309
-v: Displays detailed reply information. If you do not specify this keyword, the command displays brief
reply information.
dest-addr mask-length: Specifies an FEC by an IPv4 destination address and a mask length. The value
range for the mask-length argument is 0 to 32.
destination: Specifies the destination address in the IP header of MPLS echo requests. The default is
127.0.0.1.
start-address: Specifies the destination address or the start destination address. This address must be an
address on subnet 127.0.0.0/8—a local loopback address. If you specify the start-address argument
without the end-address argument, the start-address is the destination address in the IP header. The
number of MPLS echo requests to be sent is determined by the -c count keyword. If you specify both the
start-address argument and the end-address argument, you specify a range of destination addresses and
the destination addresses increase in turn by the address-increment, starting from the start-address to the
end-address. The number of MPLS echo requests to be sent with each of the destination addresses is
determined by the -c count keyword.
end-address: Specifies the end destination address. This address must be an address on subnet
127.0.0.0/8—a local loopback address.
address-increment: Specifies the increment value by which the destination address in the IP header
increases in turn. The value range is 1 to 16777215 and the default value is 1.
Examples
# Verify the connectivity of LSPs to destination 3.3.3.9/32.
<Sysname> ping mpls ipv4 3.3.3.9 32
MPLS ping FEC 3.3.3.9/32 with 100 bytes of data:
100 bytes from 100.1.2.1: Sequence=1 time=49 ms
100 bytes from 100.1.2.1: Sequence=2 time=44 ms
100 bytes from 100.1.2.1: Sequence=3 time=60 ms
100 bytes from 100.1.2.1: Sequence=4 time=60 ms
100 bytes from 100.1.2.1: Sequence=5 time=76 ms

5 packets transmitted, 5 packets received, 0.0% packet loss
Round-trip min/avg/max = 44/57/76 ms
# Verify the connectivity of LSPs to destination 3.3.3.9/32, and specify the following parameters:
• Set the number of MPLS echo requests to be sent with the same destination address to 3.
• Display detailed reply information.
• Specify the range of destination addresses in IP headers as 127.0.0.1 to 127.0.0.3, and set the
destination address increment value to 2. With this configuration, the destination addresses are
127.0.0.1 and 127.0.0.3.
<Sysname> ping mpls –c 3 –v ipv4 3.3.3.9 32 destination 127.0.0.1 127.0.0.3 2
MPLS ping FEC 3.3.3.9/32 with 100 bytes of data:
Destination address 127.0.0.1
100 bytes from 100.1.2.1: Sequence=1 time=49 ms Return Code=3(1)
Destination address 127.0.0.3
100 bytes from 100.1.2.1: Sequence=2 time=44 ms Return Code=3(1)
Destination address 127.0.0.1
