Hi,I am trying to configure two 2600 series routers to run in a Frame Relay network with an ISDN dial line as backup operation. The Frame Relay configuration is working alright but the ISDN is not.
With reference to the figure below : R1---S1----Frame Relay----S0---R2 \---Bri0-----ISDN------Bri0---/ The problem is with reference to R2 being the sender : - if serial link of both routers are brought down, the ISDN will activate. - if only 1 serial link of either router is brought down, the ISDN will not activate. The same case happen with R1 being the sender. I am struck with this for weeks, really appreciate very much if you can help to chk my router config. My configurations of both routers are as below : R1 configuration : ! version 12.0 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname R1 ! username R2 password 0 cisco ! no ip domain-lookup ! isdn switch-type basic-ni ! interface FastEthernet0/0 ip address 172.16.32.1 255.255.240.0 ! interface Serial0/1 backup delay 10 40 backup interface Dialer1 ip address 172.16.96.1 255.255.240.0 encapsulation frame-relay cdp enable frame-relay map ip 172.16.96.1 17 ! interface BRI0/0 no ip address no ip directed-broadcast encapsulation ppp dialer pool-member 5 isdn switch-type basic-ni isdn spid1 51055512340001 5551234 isdn spid2 51055512350001 5551235 ! interface Dialer1 ip address 172.16.16.1 255.255.240.0 no ip directed-broadcast encapsulation ppp dialer remote-name R1 dialer idle-timeout 300 dialer string 5554000 dialer string 5554001 dialer load-threshold 128 either dialer pool 5 dialer-group 1 ppp authentication chap ppp multilink ! router igrp 100 passive-interface Dialer1 network 172.16.0.0 ! ip classless ip route 0.0.0.0 0.0.0.0 172.16.96.2 ip route 0.0.0.0 0.0.0.0 172.16.16.2 200 no ip http server ! dialer-list 1 protocol ip permit ! line con 0 transport input none line aux 0 line vty 0 4 password project login ! end R2 configuration: ! version 12.0 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname R2 ! username R1 password 0 cisco ! no ip domain-lookup ! isdn switch-type basic-ni ! process-max-time 200 ! interface FastEthernet0/0 ip address 172.16.48.1 255.255.240.0 no ip directed-broadcast ! interface BRI0/0 no ip address no ip directed-broadcast encapsulation ppp dialer pool-member 1 isdn switch-type basic-ni isdn spid1 51055540000001 5554000 isdn spid2 51055540010001 5554001 ! interface Serial0/0 backup delay 10 40 backup interface Dialer1 ip address 172.16.96.2 255.255.240.0 no ip directed-broadcast encapsulation frame-relay frame-relay map ip 172.16.96.2 16 ! interface Dialer1 ip address 172.16.16.2 255.255.240.0 no ip directed-broadcast encapsulation ppp dialer remote-name R2 dialer idle-timeout 300 dialer string 5551234 dialer string 5551235 dialer load-threshold 128 either dialer pool 1 dialer-group 1 ppp authentication chap ppp multilink ! router igrp 100 passive-interface Dialer1 network 172.16.0.0 ! ip classless ip route 172.16.32.0 255.255.240.0 172.16.96.1 ip route 172.16.32.0 255.255.240.0 172.16.16.1 200 no ip http server ! dialer-list 1 protocol ip permit ! line con 0 transport input none line aux 0 line vty 0 4 password project login ! end Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=27288&t=27288 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
