problem using isdn
|

| I have a cisco 1600 router, and 7 nt1's.
The telco says 6 are point to point isdn lines, and 1 is a multipoint line.
Only the multipoint line works. This is correct, because this is the default setting.
I understood I can change this setting, but it gives an error every time i try it.
Thich is the command reference where it says it should be possible. ios version 12.0(3)
http://www.cisco.com/univercd/cc/td...sdial/csbri.htm
Router says invalid command..
Anyone able to help? | |

| I may be way off base here, as I don't fully understand your problem.
To get the point-to-point to work try specifying it in the command line when you first establish the subinterface.
eg: From the BRI interface...
hostname(config-if):interface bri0.123 point-to-point
Then use this on the nt1's or whatever it is you are trying to do.
Sorry for the lack of guidance. I actually have a wedding to attend... not mine thank god! If you find a solution then please post it so I can see. | |

| What do you mean with:
"To get the point-to-point to work try specifying it in the command line when you first establish the subinterface."
"hostname(config-if):interface bri0.123 point-to-point "
When I do this, I get the following error:
hostname(config)#interface bri0
hostname(config-if)#interface bri0.123 point-to-point
^
% Invalid input detected at '^' marker.
hostname(config)#interface bri0
hostname(config-if)#interface bri0.1 point-to-point
^
% Invalid input detected at '^' marker.
hostname(config-if)#interface ?
% Unrecognized command
The ^ marker is under the bri0 part.. | |

| Try a config along similar lines to this:
!
isdn switch-type basic-5ess
!
interface bri 0/0
ip address 172.16.1.1 255.255.0.0
encapsulation ppp
dialer map ip 172.16.1.2 name denver 55512121010
dialer-group 1
ppp authentication chap
!
dialer-list 1 protocol ip permit
!
I 'borrowed' this from www.routergod.com and I make no apologies for blatant plagiarism 
Meanwhile, why not check that web site anyway; loads of useful hints on all sorts of Cisco topics.

Where are you The Netherlands. I ask because I worked for AT&T at Hoofddorp for a year alongside a guy called Geert.
Just curious

| Well my configuration is not any different from your, except for the switch type.
isdn switch-type basic-net5 here in the netherlands.. I never worked for at&t.
I don't need any configs,I'm just curious about how to switch pointopoint and multipoint settings (no not the ppp protocol):-) |
