Re: Help with Error: DHCP-OPTION82 relay agent receive, bogus giaddr

Do you have a helper address configured on any interfaces?

Yeah the helper addresses are configured on the interfaces which are showing in the log but the Option82 is not enabled

Do you have a helper address configure on the interface of the backup controller, as well?  Is the interface of the controller the default gateway of the clients?  Option 82 is erroneous and will be removed from that log message.

Yeah the helpers are configured on both on all the VLANS

 

Yes the controller is the default gateway for the client VLANs

Hold on:

 

You have a backup controller that is also the default gateway for clients?

No the VRRP is created on the controllers for each client VLAN - with the VRRP address of each VLAN listed as the default gateway.  Therefor whichever controllers is the active will be the correct gateway.

Hopefully both controller VLAN  interfaces have the same subnet mask.  What is the bogus giaddr that the controller is complaining about?

Yes they have the same subnet masks.

 

So for one of them, the primary controller is complaining the bogus address is the IP that is assigned to the one of the client VLANs on the secondary controller

Re: Help with Error: DHCP-OPTION82 relay agent receive, bogus giaddr

So, how many client VLANs do you have on these controllers?  Is that the only client VLAN that it is complaining about?

Re: Help with Error: DHCP-OPTION82 relay agent receive, bogus giaddr

On these particular controllers there is two client VLANS.  It is only complaining about that one and they are setup the same.  


I have another two controllers on another site which is complaining about both client VLANs. 

 

Then I have another two controllers on another site that is not complaining at all.  All set up the same and using the same firmware versions.  Strange just trying to get to the bottom of it so it stops generating the logs.
