Here's a stumper for you. I have a Cisco 871 with 1 Ethernet WAN port and built-in 4 port switch. What I need to do is to use the same subnet on both the WAN and LAN/switched interfaces AND apply a QoS policy to the WAN interface.
My main problem is bridging the subnet from the WAN port to the switched ports. My attempt at this config did not work (see attached config file).
I need to get this running ASAP, since it's for a customer. Any ideas?
Thanks, in advance!

Well I'm guessing it would be something like this:

bridge 1 route ip

Ahh, the BVI interface, forgot about that guy. Should I use bridge irb or the default crb?
Thanks,

i use bridge irb myself. when i originally set mine up, i just chose that from the configuration examples.

Thanks Tekha, this works as long as you also have "bridge irb" in the config. I appreciate the help!
