ISP ADSL ---- Cisco 877 Router ---- Cisco ASA 5505
I have the above connection. I'd like to avoid using NAT on the Cisco 837 router, and just put the ASA directly on the Internet. However, I have to use the 837 to connect to the ISP - the ASA doesn't have an ADSL interface.
I know how to configure the ASA to handle the pppoe connection, but not how to configure the 837 to act as a bridge between ADSL and Ethernet.
Is this what is called RFC1483 bridging?
Will the following config allow the ASA to do all the pppoe negotiation, and leave the 877 doing nothing more than bridging ethernet and ADSL?:
no ip routing interface Ethernet0 no ip address no ip directed-broadcast bridge-group 1 encapsulation aal5snap bridge-group 1 bridge 1 protocol ieee
Unfortunately, this is our only site with an 800 series router connecting to the internet, so I am not very familiar with it, and I won't be able to test the configuration out properly until I get there.
