Q

Can a Cisco 801 be configured on a dedicated 128KB ISDN line?

Can a Cisco 801 be configured on a dedicated 128KB ISDN line? Could you kindly provide a basic set up command for

router IP: 202.54.1.23 and remote router IP: 61.11.24.4 Try this:

interface BRI0
 ip address 202.54.1.23 <subnet mask>
 encapsulation ppp
 dialer map IP 61.11.24.4 name <other router hostname> <its SPID>
 dialer-group 1
 ppp authentication chap
 isdn spid1 <number>
 isdn spid2 <number>
 ppp multilink 
 dialer load-threshold <load> either

dialer-list 1 permit ip any any

Here you can specify 1 to bring both channels up at the same time. if you specify 255 second channel will come up when first is 100% utilized and similarly you can give any number between 1 – 255.

Similarly you can configure the other end.

interface BRI0
 ip address 61.11.24.4 <subnet mask>
 encapsulation ppp
 dialer map IP 202.54.1.23 name <other router hostname> <its SPID>
 dialer-group 1
 ppp authentication chap
 isdn spid1 <number>
 isdn spid2 <number>
 ppp multilink 
 dialer load-threshold <load> either

dialer-list 1 permit ip any any
