ISDN config help required 2

[adrianday]

Can anyone help me by providing the necassary info on how to set up 2 1600 range isdn routers. I have read a number of articles, most describe N. American scenarios I'm in the UK, and have been left quite confused by what i have read.

Hi

This one works, but you will need to add your dialer string, passwords, username and access lists (i've started it with the permit statement). Also, if it is for DDR you will need to filter RIP or face death by thousand pound phone bill.

Current configuration:
!
version 12.1
no service pad
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
!
hostname xxxxxxxx
!
enable password xxxxxxxxx
!
username xxxxxxxx password xxxxxxxx
!
!
!
!
ip subnet-zero
!
no ip domain-lookup
isdn switch-type basic-net3
!
!
!
interface Ethernet0

ip address xxxxxxxx xxxxxxxxxx
no keepalive
no shutdown
!
interface BRI0

no ip address
encapsulation ppp
dialer rotary-group 1
isdn switch-type basic-net3
no cdp enable
no shutdown
!
interface Dialer1
ip unnumbered Ethernet0
encapsulation ppp
no shutdown

dialer in-band
dialer idle-timeout 60
dialer map snapshot 1 name xxxxxxxxx broadcast xxxxxxxxxxx (dial string)
dialer map ip xxxxxxxxxx name xxxxxxxx broadcast xxxxxxxxxx (dial string)
dialer hold-queue 10
dialer-group 1
snapshot client 15 360 suppress-statechange-update dialer
no cdp enable
ppp authentication chap
!
router rip
version 2
network 10.0.0.0
no auto-summary
!
no ip http server
ip classless
!

access-list 100 permit ip any any
dialer-list 1 protocol ip list 100

!
line con 0
exec-timeout 0 0
password xxxxxxx
login
transport input none
stopbits 1
line vty 0 4
password xxxxxxx
login
!

!
!
end

For DDR, remove RIP --

no router rip

and add static route(s). That should do you.

 

[adrianday]

thnx i will give that a go later

 

[StarTAC]

correct, or you could keep the BRI interface off the routing protocol stream with the command..

router rip
passive-interface bri 0

that suppresses routing updates on the BRI 0 interface..

good luck..

Yes, the previous posts are correct. The configs and documentation are all the same US to UK, the only difference is in how you setup the dial strings (basically phone numbers). Wait, I just noticed something...
Shouldn't there be under the interface BRI0 statements about the spids? Such as:

isdn spid1 xxxxxxxxx
isdn spid2 xxxxxxxxx

To add to what trismegistus said about filtering, make sure you use access-lists to filter out any uninteresting traffic (broadcasts, etc.) The boss will not be happy when a 1000 quid telco bill shows up.

I dont agree startac,because configuration has the command
snapshot client 15 360 suppress-statechange-update dialer
