Hi Janto,
It looks like you're trying to connect R8 to R1 via an ethernet link, but
you have different ip network addresses on either side of the link. Can
this be?
Also, what do R6 and R5 have to do with dlsw in your topology? Keep in mind
that Dlsw is basically a tunneling protocol in which SNA and Netbios packets
are encapsulated inside IP pkts. So, as long as you have ip connectivity, u
can use Dlsw. Therefore, if you're using IP features (backup interface,
floating static routes, or dialer watch) to provide redundancy between R6
and R5, that's independent of Dlsw.
If, however, isdn is providing the only connectivity for Dlsw, then you
would use some of the dlsw paramters you wondered about. Take a look at the
section on Dlsw on cisco's web site. They provide a number of examples of
using DDR with Dlsw.
Jim
