Nope. It's a little bit different.
With two peers with different costs, the 'local' router will of course use
(usually) the one with the lowest cost. However the other router will be in
a CONNECT state (capability exchange,etc. has taken place and keepalives are
being sent (assuming that keepalives are not set to 0)).
However, with a backup peer, the connection to the backup is not made until
there is a failure on the primary (so no traffic on backup path until then).
Hope this helps,
Mark
