We have changed the number of router's loop back address. We are using loop back address as source interface for radius authentication.
ip radius source-interface Loopback0.
Most of the routers working fine but few routers have problem with radius authentication.Seems it is still taking old ip as source address even though old IP address does not exits.Once I reboot the router it works fine and taking new IP as source IP.
Just wondering if there is anyway to solve the issue without rebooting the router.Please suggest me.
