Good Evening,
I am having issues working this lab where item 5 states "both routers
must be capable of initiating ISDN calls" . Solie's solution places the
backup interface cmd on both routers' serial interface. On my lab, this
brings both sides into a standby state and neither will call the other.
When removing the backup interface cmd off one router, backup works well
except the B channels start to disconnect on the called router after the
120 second timeout.
Is Solie incorrect on this config? If not, can someone tell me what I
am doing wrong?
Below is the config where R1 will call R2; however, R2 disconnects the
call after 120 seconds:
R1-Greenbay
interface BRI0
ip address 170.20.20.1 255.255.255.252
encapsulation ppp
dialer map ip 170.20.2.2 name R2-SanDiego broadcast 6785556789
dialer map ip 170.20.2.2 name R2-SanDiego broadcast 6785559876
dialer load-threshold 1 either
