ubr7100 bridge mode

[kej]

hi i used the online dokumentation about setting the ubr7100 in bridge-mode. It works perfectly with the ios 12.1 software.

But when i try to use 12.2 software it won't work. The modem behind the cmts requests for an dhcp and it gets one. Then it tries to get its configuration from the tftp server. On the server i see 2 arp request (and 2 arp replies) and nothing further happens. I use arp proxy, and the cmts configuration is just like the one in the online documentation.

How do i get this to work with 12.2 software? :)

I'm not a 100% sure about this but I have been told that only a few images support bridging on the uBR7114 (one that I know works is the 12.1EC). You need to look at the support for bridging on your image.
