On Vader, don't have a remote peer to skywalker, and use promiscuous on the
local peer. That way, it will only peer to skywalker, if skywalker requests
it.

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,
