Be most grateful if someone could check this out.
I have a (nuther make ) wireless router that I wish to attach to the 877 via one of the FA ports
877 has 12.4 Enterprise IOS / 256 RAM / 40 flash
( I would love to use an 877W -- but Cisco have not upgraded to Gigabit ports or 802.11n wireless yet )
I require the Cisco to treat this ONE port as a pure ADSL bridge ( passthrough ) -- No NAT or IP Routing
( the other wireless router will do this )
I am trying to bridge one FA port ( VLAN ) to the ATM interface using IRB
To do this I have a bridge-group set on the ATM (sub) interface as well as on the VLAN in question.
To complicate things I also have some PPPoE dialers to different ISP's using dynamic IP addressing PPP IPCP on the same ATM interface.
pppoe-client dial-pool-number 2
pppoe-client dial-pool-number 1
In this country we can only use ONE ATM PVC for ADSL
I understand that you cannot bridge & route on the same interface.
As I understand it the PPPoE routing is taking place on the dialer interface so therefore bridging should be possible on the ATM (sub) interface
This does not appear to be working ? I have been advised by a Cisco "fundi" that this scenario is not possible.
ie it is not possible to set up one port on the 877 for bridging ( the "modem" -- ATM) and the others for routing.
I would appreciate it if someone could confirm this -- possible / not possible
If I am doing something wrong and have been misinformed I would appreciate it if someone could explain the correct way of doing this.
