Re: NAS configure with 2 ip address failed on AAA authentication
The AAA server identifies the client by a single IP address and the client always needs to use that address as the source address. If you have 2 BVI interfaces it may be that sometimes the source address is one and sometimes the source address may be the other. That would account for the fact that sometimes it promts for user authentication and sometimes it does not prompt.
If using 1 BVI as the source address creates the potential that sometimes it might not work because that interface was down but the other BVI was up, then perhaps you should consider configuring a loopback address and using the loopback address as the source address. If the loopback was the source address then it would not matter which BVI might be up and which might be down.
