You can't authenticate (login) to two radius servers - otherwise you might get conflicting responses.

You can configure your router for redundancy so that it contacts the subsequent radius servers after your primary server fails to respond. Just add additional radius-server host entries for other radius servers.

You can, however, send accounting information to more than one radius server:

Configuring AAA Broadcast Accounting

The following example shows turning on broadcast accounting using the global aaa accounting command:

aaa group server radius isp

server 1.0.0.1

server 1.0.0.2

aaa group server tacacs+ isp_customer

server 3.0.0.1

aaa accounting network default start-stop broadcast group isp group isp_customer

radius-server host 1.0.0.1

radius-server host 1.0.0.2

radius-server key key1

tacacs-server host 3.0.0.1 key key2
