Internal DHCP for IAP showing IP 172.31.98.x with mask 255.255.254.0 (default)

Hi,

 

I have around 10 different clusters of IAP and in these a few of them (around 3) are providing 172.31.98.x IP for the guests from the internal DHCP, which should not be the case. I verified all clusters for the dhcp pool and it showed172.16.22.0/24 subnet, as they have been setup.

 

Attached is the screen capture for show ip route and the dhcp pool.

 

Even i tried to remove the route manually, it still remains there. Has anyone faced this issue? I also upgraded the IAP image to 6.4.2.6-4.1.1.9_51442 with no results.

That's probably from the Magic VLAN scope (VC assigned)
Thank you

Thanks for your reply.. how do i take it out? I cannot find this in the pool I created in the DHCP server of VC (see the screen shots). What I believe is for the pool I created, the VC should have a static route something like:

 

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
172.16.22.0     0.0.0.0         255.255.255.0   U         0 0          0 br0

 

This route is displayed for the other clusters where i have setup the guest dhcp pool. But these 3 clusters of IAP which I set up recently provide IP by the "Magic VLAN scope" even though I have configured a different pool. Also, they show the route:

 

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
172.31.98.0     0.0.0.0         255.255.254.0   U         0 0          0 br0

 

Any suggestion would be appreciated, I do not want to delete the config and start over again with theseas they are in production environment now.
