This is a basic dialer config based on using a PRI rate E1 line (europe)for your central site and a BRI rate line for your remote sites (just one dialer example shown)

Central site

username Router_A password xxxx

controller E1 x/x

pri-group timeslots 1-31

Interface serialx/x:15

no ip address

encapsulation ppp

dialer pool-member 1

isdn switch-type primary-net5

fair-queue

ppp authentication chap

interface Dialer1

bandwidth 64

ip address 192.168.250.158 255.255.255.252

encapsulation ppp

no ip mroute-cache

dialer pool 1

dialer remote-name Router_A

dialer idle-timeout 1800

dialer string 9876543210

dialer-group 1

priority-group 1

compress stac

ppp authentication chap

ip route 10.10.10.0 255.255.255.0 192.168.250.157

_____________________________________

Remote Site (router_A)

username Central password xxxx

interface BRI0

no ip address

encapsulation ppp

dialer pool-member 1

isdn switch-type basic-net3

ppp authentication chap

Interface Dialer1

ip address 192.168.250.157 255.255.255.252

encapsulation ppp

dialer pool 1

dialer idle-timeout 1800

dialer string 0123456789

dialer max-call 1

dialer-group 1

priority-group 1

compress stac

ppp authentication chap

ip route 0.0.0.0 0.0.0.0 192.168.250.158

this is just the basics

hope this helps

Hi Stu,

thanks a lot for help. What does dialer max-call 1 and priority-group 1 mean?

We will coonect both sites with T1/E1 line.

Is over there difference?

Thanks a lot for help.

Hi John

the dialer max-call 1 is an optional command which would stop multilink from using more channels (if multilink was configured which it isn't in this example so its not really needed).

The priority-group 1 command attaches a prioritised list (1 in this example)of traffic to the dialer interface ( its a QOS thing).

Below is an example of some prioritised traffic (telnet).

priority-list 1 protocol ip high tcp telnet

priority-list 1 protocol ip normal

If there is congestion in theory telnet should be prioritised before the rest of the ip traffic..

Hi Stu,

Thanks a lot for a help.

It shouldn't be any different. If you set up each ends controller, its timeslots and configured the d channel for each you can simply create dialer interfaces similar to above.

please rate if helps
