Hi Janto,
Here's a "known good" config for dlsw w/backup that I use quite often. Why don'
t you peruse this and see if you can find your problem.(see below) Also, you'll
make it easier to help you if you remove unrelated syntax from your configs be
fore sending them. This Alaskan temperature makes a Florida boy lazy! ;-)

Subject: DLSW+ Backup
Hi All,
I have problem when configuring DLSW+ Backup feature.
The network model same like in page 907 of Karl Solie's CCIE Practical
Studies Vol. I book.
I tried to configure backup peer for router skywalker, the primary peer
is router solo, and the backup peer is router vader.
The DLSW+ configuration for the each router is like below:

Below is the result of 'show dlsw peer' command for each router:

The question is why the peer connection between skywalker and vader can
be CONNECT ?
Is this correct ? Pls help me.
TIA,
