NAC DHCP server subnet-list issue

Hello everyone,

I currently setup the CAS as a layer 3 IB deployment, and use the CAS as the DHCP server for our remote subnets.

My issuse is when I configure the IP address pool, I have to check option "Retrict range to REALY IP", and can only put one IP address of the remote router IP address to make the DHCP server function working.

But our remote routers are configured HSRP for the user subnets, and I find that it use the physical ip address instead of the virtaul ip address to encapsulate the DHCP rely packets. If I put the HSRP virtual IP, it could not work. If I put the primary router's physical interface IP, how about it failover to the standby router?

Could anyone help me for this problem?

Thanks in advance.

Jason
