The dialer map for llc2 is not required to make dynamic peers over ISDN
work. I tried this while at the ECP1 class and just doing the normal dialer
map for ip (and using the dialer-list to allow ip or - more specifically -
the TCP ports mentioned below) works well.
Perhaps this adds some functionality of which I'm not aware??
Rob.

I asked my self the same question about his configs. I know that if you are
asked to configure ONLY dlsw over ISDN, then I would do an ip extended
access list permitting tcp ports 2065, 2067, 1981, 1982, and 1983. Of
course, it does work with permitting ip because of it being encapsulated in
IP. Maybe someone else can shed some light on the Nam-kee config.

Subject: dlsw over isdn
Group,
In the book "Configuring cisco routers for bridging,
dlsw+ and desktop protocols" by Tan Nam-kee, on page
132 it shows dlsw over isdn by using dynamic peer on
one side and promiscous on the other. I understand
this, becuase you don't want dlsw keeping the line up.
however, he then adds:
dialer map llc2 name c3640-r3 broadcast 3245652
and
dialer-list 1 protcol llc2 permit
Does this mean that dlsw isn't encapsulated into ip by
the time it decides to use the isdn line? I thought
it was ip and the statement:
dialer-list 1 protocol ip permit
should now handle the dlsw.
I searched the archives and found 3 inquiry's into
this topic so it hasn't been discussed much, I also
searched the cisco doc's under dlsw's and the only
thing I found on dlsw over ddr was:
dlsw netbios-keepalive-filter.
Anybody have any thoughts on the right way to do dlsw
over isdn.
Thanks,
Bill
