Hi,


I need a template that I can use to configure ISDN backup on a 1700,2600 and 2800 router.


These routers are based at client sites and I need them to dial into one of my Routers.


Any help is appreciated.


Thanks

this is for demand dialing with interesting traffic.

----------------

interface bri0

ip address

encapsulation ppp

no ip route-cache

no ip mroute-cache

dialer idle-timeout

dialer map ip name broadcast

dialer load-threshold 100 outbound

dialer-group

isdn switch-type

isdn spid1 <0101,depends on the carrier switch-type>

isdn spid2 <0101,depends on the carrier switch-type>

no fair-queue

ppp authentication chap

ppp multilink


------------------


with the appropriate floating static route and acl, the isdn will kick in when an interesting traffic is generated, when the serial goes down.


Also, authentication password should be the same at each side.
