Traffic at interface not match between two Router (point-to-point P -->PE)

Hi All,

 

Need your expertise regarding my problem. Currently our network is point-to-point network P --->PE router. The problem is the input traffic display at interface PE not match with Output interface at P router. FYI it's happen at all interface input PE router . Is it normal or something wrong. Just additional information our user don't complain about performance network. So it's very2 weird. I already open JTAC case 2011-0920-1061 and still waiting feedback. Hopefully someone in this forum can help me.

 

P Router = MX960

PE Router MX480

 

Junos Version 10.0 R3

 

 

{master}
P-Router> show interfaces ge-0/0/6 | match rate
  Input rate     : 63623408 bps (34920 pps)
  Output rate    : 310916416 bps (41093 pps)

 


PE-Router> show interfaces ge-0/0/6 | match rate
  Input rate     : 23184 bps (32 pps)
  Output rate    : 67465808 bps (35623 pps)

Can you post your show chassis hardware output of your PE router ? Want to know if FPC0 is a DPC type or MPC.

Hi Fox,

 

 

Is this problem related to hardware type?

if you are using DPC type FPC, and vrf-table-label in your routing-instances, then that explains it.  You should not see the issue with 10GE ports on DPC or ports on MPC. 

Have you tried with vt- interfaces under the routing-instance?

That's why i was asking about your HW.

This might help:

"When you configure the vrf-table-label statement, MPLS packets with label-switched interface (LSI) labels that arrive on core-facing ATM or Frame Relay interfaces, or on aggregated Ethernet interfaces configured with VLANs or Ethernet interfaces configured with VLANs, are not counted at the logical interface level."

Re: Traffic at interface not match between two Router (point-to-point P -->PE)

is it directly connectd on same POP or TX is in between?
Is it including any L2 switches in between.
Basically..This traffic difference is dude L2 headers being applied and removed by both routers in both direction..
I had long round of discussion with our engineering team as well as ATAC..bt tht was between EX and MX..
One more r u using any vlan tagging in betweeb..understnd tht MX is hybrid bix whch can append and remove the L2 material..we need to understnd..

Verify monitor interface ge-0/0/6 at both ends somentaneously and u ll verify is thr is difference..
Definitely thr is no issue bt we need to understnd hw JUNOS behaves as far as input and out monitor traffic utility is concern on MX platform..
Hope this helps..

Hi All,

 

 

Sorry for late reply. FYI the connection is point-to-point directly. Also both connection is 10G. Is there any info that u need. Thanks and appreciate someone feedback.
