Dear Experts,
I am runnging out of idea regarding one issue I am facing.
Indeed, I failing to get MPLS VPN traffic b/w two juniper mx PE routers.
Below is an overview of the architecture :
HOST-A <<<>>>> PE1<<<< OSPF+MPLS RSVP+L3VPN>>>>>PE2<<>>>>HOSTB
Low Level, I do have PE1<<<<<<TX1(L2)>>><<<<<TX2(L2)<<<>>>>PE2
I have tried to mirror the port at either interfaces facing PE1/PE2 (Or b/w PE1<<<>>T1 and other side also).
Unfortunately, I could get only OSPF (with BFD) and RSVP signal traffic. Nowhere, I could see the MPLS VPN traffic.
Test Case 1 -- No MPLS VPN traffic--- This is the way I use to pick traces which always works. But could see the traffic utilization is more than 300 Mbps. How comes I am getting only control traffic ?
set forwarding-options port-mirroring input rate 1
set forwarding-options port-mirroring input run-length 1
set forwarding-options port-mirroring family inet output interface ge-1/0/7.0 next-hop 1.1.1.2
set forwarding-options port-mirroring family inet output no-filter-check
set firewall family inet filter port-mirror term 1 then port-mirror
set firewall family inet filter port-mirror term 1 then accept
set firewall family inet filter port-mirror term 2 then accept
set interfaces ge-1/0/5 unit XXX family inet filter input port-mirror
set interfaces ge-1/0/5 unit XXX family inet filter output port-mirror
Test Case 2 -- No MPLS VPN traffic--- This is the way I use to pick traces which always works. But could see the traffic utilization is more than 300 Mbps. How comes I am getting only control traffic ?
Since TX node is used as a switch, I've mirrored the related port to check... It was same content.
Required Help :
1. Is this behaviour normal ? what could explain this ?
2. If the case, it means the nodes (TX) in b/w cannot manage the QoS from packet coming from PEx ? This is what is being observed. Only control traffic (OSPF hello, RSVP, etc--> DSCP CS6) can been seen in qos map at TX side while the MPLS VPN traffic (huge) is all reflected in default queue (DSCP BE) and not visible with wireshark. Please advise.
Note: I used two differents laptop for the test.
