Since a few weeks I have a cisco 827 adsl router/modem and a DSL connection from Demon Internet (in Holland) encapsulation protocol RFC1483 LLC Bridged IP.
I got the internet connection working, The virtual interface BVI1 gets a static IP# by dhcp (I keep the same IP address) from Demon with a lease time of 30 minutes and a refresh time of 15 minutes. Internet works perfect for 15 minutes, but after 15 minutes when the IP address is refreshed (with the same number) I get the debug message "interface BVI1 is attempting to shutdown" and I'm disconnected.
The temp.solution is to give a shut to bvi1 and a no shut and it works again.
I also tried to give BVI1 a static IP address (wich came from the dhcp server from Demon), but this is not accepted by Demon. I also gave BVI1 a static
mac-address.
I also tried the web interface and let him search the settings, also this works, but also for only 15 minutes.
I searched the whole cisco site regarding this problem, but could't find
anything about this problem. I tried to use another modem (Alcatel speedtouch home) and this works fine.
Is someone familiar with this problem? I have a cisco 827 ADSL
modem/router with standard IP (16MB/8MB)and IOS 12.1 Early release. I think
it's a bug in the IOS version, but I could be wrong.
Can somebody please help me to get the source/solution of the problem?
