I'm not the only one having ISDN frustrations then!
I just tried your scenario.
1st Q - it works without dialer map statements at the Hub.
2nd Q - as above, how far do you go, because it will also work without
dialer-list/group on the hub??
3rd Q - Multilink brings up both lines with just one dialer map.
interface BRI0/0
ip address 192.168.1.2 255.255.255.0
encapsulation ppp
dialer idle-timeout 20
dialer map ip 192.168.1.1 325500
dialer load-threshold 1 outbound
dialer-group 1
isdn switch-type basic-net3
ppp multilink
end
Router#ping
Protocol [ip]:
Target IP address: 192.168.1.1
Repeat count [5]:
Datagram size [100]: 1500
Timeout in seconds [2]:
Extended commands [n]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 5, 1500-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
