Is CEF enabled on the 3845 ?

Yes, it is enabled.
Very strange thing is that arp requests pass (this mean that l2
connection exists), but other traffic not.
May be something is wrong with switches?
I don't phisically replaced 3660 with 3845, they both are connected
now.
But I tried to change connection from 2801 to 2811 on other side (they
are both connected too) and there are no problems...

I tested, switches works OK, mac address from far point moves to 3845
when I turn loopback 0 no shutdown and shutdown on 3660...
