Colleagues prompt why there can not pass ping mpls
on Huawei S6320 from Extrme X670 side? If to do
ping mpls with Juniper MX or Cisco ME of a series on S6320 passes a ping, also if
to check ping lsp on Juniper MX, Cisco ME, Extrme X670 everything works with S6320.

I received mpls ping dumping from Juniper MX, Cisco ME and Extrme X670 -
the single difference is that Extreme X670 in ip a packet of dst ip address 127.0.0.2
and Juniper and Cisco send on dst ip 127.0.0.1

Hi
Could you please help make a detail issue destription about this issue ? include the network topology

and also the 127.0.0.1 is same with 127.0.0.02 because both are internal loopback port, there is no difference

Also we can configuration the traffic statistics to check whrer the packets loss. for example:

acl 3001
rule permit icmp source 192.168.1.10 0.0.0.0 destination 192.168.2.10 0.0.0.0 // source address and destination address
rule permit icmp source 192.168.2.10 0.0.0.0 destination 192.168.1.10 0.0.0.0

traffic classifier ping // Create the classifier
if-match acl 3001 // Match the acl
traffic behavior ping // Create the behavior
statistic enable

traffic policy ping
classifier ping behavior ping

interface g 0/0/10 // need add the traffic policy to the traffic path both inbound and outbound
traffic-policy ping inbound
traffic-policy ping outbound

int g 0/0/20 // both traffic path port need add the policy
traffic-policy ping inbound
traffic-policy ping outbound

<huawei>reset traffic policy statistics interface GigabitEthernet 0/0/10 inbound
<huawei>reset traffic policy statistics interface GigabitEthernet 0/0/10 outbound
<huawei>reset traffic policy statistics interface GigabitEthernet 0/0/20 inbound
<huawei>reset traffic policy statistics interface GigabitEthernet 0/0/20 outbound

Then please keep pinging and then we can found where the packets not pass.

suggest you uploading your topology so that help our engineer could solve your problem more precisely.
and you'd better not upload any documentions include your public IP addressMPLS ECHO REQUEST S6320-2793863-1

Colleague , topology simple. Huawei S6320 is on tests .

Huawei S6320 (lo - 10.0.0.3/32) -- LDP , OSPF -- EXOS X670G2-72x -- LDP , OSPF -- EXOS X670G (10.0.0.5/32)-- LDP , OSPF -- Cisco ME360x (10.0.0.4/32)

1. from Cisco ME360x (10.0.0.4/32)

ping mpls ipv4 10.0.0.3/32
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/8 ms
Total Time Elapsed 24 ms


ping mpls ipv4 10.0.0.3/32 destination 127.0.0.2
.....
Success rate is 0 percent (0/5)
Total Time Elapsed 9645 ms

2 . from EXOS X670G (10.0.0.5/32)

ping mpls lsp any 10.0.0.3
Ping(MPLS) : 4 packets, 8 data bytes, interval 1 second(s).

--- ping statistics ---
4 packets transmitted, 0 received, 100% loss


Huawei does not respond to mpls echo if dst ip packet not 127.0.0.1.

Though according to RFC 4379 shall respond to any address from from the range 127/8 .

I think that's a bug.

Hi, VSH the 127.0.0.1 is same with 127.0.0.2 because both are internal loopback address, there is no difference
they are local route.
If you still have inquiry about this, suggest you to contact huawei tac to open a ticket.
thanks very much.

To connect to other vendors' devices, we need to know more about them.
