You don't use realms to fail over. Look at proxy.conf, Alan DeKok has already pointed to it. I quote from it (from line 514 onwards): 

#  This section defines a pool of home servers that is used
#  for fail-over and load-balancing.  In earlier versions of
#  FreeRADIUS, fail-over and load-balancing were defined per-realm.
#  As a result, if a server had 5 home servers, each of which served
#  the same 10 realms, you would need 50 "realm" entries.

Not anymore.

So, in version 3, you define this:

home_server motp_1 {
     type = auth+acct
     ipaddr =
     secret = test

home_server motp_2 {
    type = auth+acct
    ipaddr =
    secret = test

Then you define a home_server_pool for failover:

home_server_pool motp_failover {
    type = fail-over
    home_server = motp_1
    home_server = motp_2

Then you define the realm:

realm {
    pool = motp_failover

realm motp {
    pool = motp_failover

This 'should' work (based on the little bit of information you've given us).
