Hello people,
has anyone ever seen these errors and can tell me the reason?
The errors always occur at XX:29:25 and XX:09:25.
- The clients are all configured to DHCP.
- The VLANs are configured Layer 3 on the switches.
- The DHCP server is on the MX84 (relay).
Here is the configuration of the switch ports
Thank you
Did you set the dhcp server to give out the switch svi-ip as router/gateway
1- Does 10.201.10.76 belongs to vlan 340 ? RPF checks are failing. refer to the documentation below
2- The reason why it shows every 30 mins : Every 30 minutes, the top 3 offending clients are logged on dashboard in Network-wide > Event Log. These events are visible in the event log after filtering for Source IP and/or VLAN mismatch.
3- Last resort you can disable the IP spoofing to temporarly allow the trafic.
Hi guys and thanks for your answers.
I have followed these instructions.
https://documentation.meraki.com/MS/Layer_3_Switching/Layer_3_Switch_Example
This is my Transit VLAN
and on the Switch
as an example the VLAN 340 on the switch. As DHCP Relay I have chosen the Transit VLAN
This is my static route on the MX
and the DHCP server on the MX
this is my configuration for the switchport
this way I have created three VLANs on the switch and DHCP servers on the MX.
I am not sure where my mistake is.
I hope I have described everything understandably and you can help me.
Thanks a lot
any idea?
