Switching affected by routing uplink
hi, I have a situation that I can not make sense out of. Netgear 10G switch is connected to a Cisco L3 Linksys switch at 1Gbps speed, there is only one VLAN configured on Netgear, two hosts are conne...
I have a confirmed bug that has been passed from L3 support to the software developers to fix that is very similar to this. The switch is a M4300-24X24F with the latest firmware.
My setup is a bit more complicated. I have five VLANs using policy based routing to set a different gateway for each VLAN but I get a similar problem. Any equpment attached to the switch can directly connect to any other equipment if it is in a different VLAN but if the equipment is in the same VLAN the traffic gets sent to the default gateway (which it clearly shouldn't as the equipment is connected to the switch and the devices appear in the ARP table).
Hi TCan,
The problem you said should be worked as design, as all of traffic Inter-VLAN or Intra-VLAN match to PBR policy, so the traffic was redirected to router.
If you want intra-VLAN traffic not forwarding to router, you should config IP ACL to exclude these traffic, make sure the ACL only match the traffic that belong to Inter-VLAN.
So I think it not same as this problem.
Hi EricZ
I have to disagree with what you have said. The PBR I have used only sets a default gateway - 'set ip default next-hop x.x.x.x'. It is applied to all VLANs but should only have an effect when the traffic isn't local to the switch otherwise the traffic should be routed locally, NOT passed to the default gateway. Its a default gateway - by definition that is where to send traffic that isn't local. The PBR works correctly for inter-VLAN traffic, nothing gets sent to the default gateway, it is only intra-VLAN traffic that incorrectly gets sent to the default gateway. As I said, this has been confirmed as a bug and is awaiting a fix from your software developers.
Anyway, this isn't about my issue but I mentioned it because the symptom oldcreek describes is very similar - intra-VLAN traffic incorrectly being sent to the default gateway. The cause may be different and you have suggested he checks his subnetting. Without furhter input from oldcreek we won't know!
Hi oldcreek,
Could you please provide your switch configuration to us? It is better for us to further analysis.
How do I send configure files from my Managed Switch to NETGEAR community moderators?

Hi TCan,
Ok, we can discuss more on the issue.
