Consider this.  I have 2 2610's, each with a WIC-1DSU T-1 card in them.  I
have these T-1's connected back to back.  I have tried putting IP addreses,
using encap ppp, and everything works cool, exactly the way I would expect
it to work.  So I know the cards and the cable and all that are working
fine.

Now, I want to try to have the T-1 interfaces invoked via Dialer interfaces.
Why?  Because eventually I want to get 2 more of these T-1 cards, and
install one in each (so each router has 2 of them) and then run ppp
multilink where I bond the 2 T-1's together to form a 3 Mb pipe.

But I just cannot do it.  Specifically, I have tried various ways to get the
Dialer interface to bond to the T-1's (Serial 0/0).  It never works.  For
example, I create rotary groups.  It doesn't work.  Then I try dialer pools.
It also doesn't work.  Everything I have tried doesn't work.

For example, if I try to use dialer pools, then the router demands a dialer
string.  So I give it a dialer string.  The Dialer interface then apparently
tries to dial this string, which of couse fails because in a back2back T-1,
there is nothing to dial.  So if I try a rotary group, somehow the dialer
interface never properly seizes the T-1.  Instead I get an error like this,
whatever the heck it means:

r1#ping 192.168.20.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.20.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
r1#
01:25:59: Se0/0 DDR: rotor dialout [priority]
01:26:01: Se0/0 DDR: rotor dialout [priority]
01:26:03: Se0/0 DDR: rotor dialout [priority]
01:26:05: Se0/0 DDR: rotor dialout [priority]
01:26:07: Se0/0 DDR: rotor dialout [priority]


OK, now I have seen several CCO examples (for example the examples on PPP
multilink) where they put a serial interface (not an ISDN or an async int,
but an actual serial interface) under a Dialer interface.  But what can I
say, it has never worked for me, not once.  The only thing that can I can
think of is that all those CCO examples use 2500's, whereas I got 2600's
here.  But it shouldn't matter (or should it?).

So, has anybody (especially somebody with a 2600 with a T-1 WIC)ever
successfully put a serial interface under a Dialer interface and gotten them
to bond correctly  ?  If so, could you shoot me a config?

Thanx
