Hi,
We are running GLBP on 2 router and 2 ISP and i have connected router to ISP A and already checked their bandwidth with Iperf from WAN cable and LAN cable (behind router) and no problem. But the WAN for ISP A become intermittent when i connect LAN cable to the switch even the traffic only reach 50% of our bandwidth for ISP A. I dont see any wierd logs in switch and router. I suppressed broadcast and multicast with level 20, but WAN ISP A still intermittent, it became normal when i shutdown LAN port connected to router A. I moved the port in switch and it still happen only for ISP A, no problem at all for ISP B.
What should i do with the port?
Thanks,

hi Cornelius,
what do you mean by the term 'intermittent'? as you said the bandwidth mark is 50%, so I hardly could imagine you are having packet loss on the WAN link A during the issue is there, am I right? is that switch connected to the rest of the network? what is the traffic rate in there? perhaps some ugly worm is probing its way out?
I think to start with we'd need to have a look at 'sh interface' from all the respective interfaces, also please do explain what is 'intermittent' in that case.
Did you try to connect the same swith to ISP_B router? Did you try to connect another switch/lan device to the router A?
HTH,
Ivan.
P.S. yes, the diagram is not opening.

Hi Ivan,
my term for intermittent means that the connection to the WAN is not consistant. As my picture above, i've connected 2 router to the same Switch to support GLBP using sub-interface. The switch connected to the rest of the network.
The WAN (10.173.3.122) become unstable or intermittent if i tried to ping it when i connect LAN port (172.22.11.2) to the switch. But there's no connection issue with Router B, only to Router A.
Here's the WAN LINK sh int from Router A

Hi Cornelius,
thanks for getting back.
I would like to have a look at the same outputs taken off the part B of your setup.
Of particular interest are also 'sh policy map int
If the connection is not constant, does that mean you were able to see packets being dropped on that link? perhaps some pings were showing you some loss rate? The interface tells us 'Total output drops: 31' so I wouldn't expect a constant loss rate in there.
BR,
Ivan.

Hi Ivan,
Thanks for your response,
from ping result, i see some lost rate like this :

You have a cable problem. The "reliability" value should be 255/255

Hi Leolaohoo,
If the LAN interface cable is the problem, then why unstable connectivity happen on WAN interface when i try to ping the WAN IP address from the opposite router?

Hi Cornelius,
Maybe I'm wrong. But something just DOES NOT ADD UP with your initial post.
According to your initial post, this interface's counters was cleared "5d18h". Look at the "Total output drops". That's not good. Next, look at the input and output errors. Input has some "frame" errors. Output has "unknown protocol drops". Of course the "reliability" is 250 is another thing.
I'm no expert what "frame" and "unknown protocol drops" errors are but my first reaction would be to swap out the cable.

Hi Cornelius,
thanks for additional outputs. Let's have a look at 'sh interface' outputs taken off the leg B of your topology, like you have done before for the leg A - from the router B interfaces, and the switch interface towards router B. As I said, I would like to narrow down the QoS/oversubscription matter.
Have a great day,
Ivan.
