Is it possible to use a cisco 861 together with a DSL modem being a bridge?

Is it possible to store the dsl login credentials on the 861, and use a dsl modem as the bridge? That way if you disconnect the cisco router, you dont have internet access.

Thanks

Re: Is it possible to use a cisco 861 together with a DSL modem

Hello David,

yes it is possible if you have a PPPoE service from DSL provider:

in this case the C861 acts as the PPPoE client.

the DSL modem just needs to perform half bridging by carrying ethernet frames (including PPPoE) over the DSL link inside ATM PDUs.

so first step is to check if C861 can be configured as a PPPoE client.

Hope to help

The dsl provider gives PPoE service.

The question is, can the C861 act as a PPoE client?

Thanks

The 861 can definitely be a PPPoE client. The configuration is as follows:

interface FastEthernet4

no ip address

duplex auto

speed auto

pppoe enable group global

pppoe-client dial-pool-number 1

!

interface Dialer1

mtu 1492

ip address negotiated

encapsulation ppp

dialer pool 1

dialer-group 1

no cdp enable

ppp authentication chap pap callin

ppp chap hostname ispuser

ppp chap password 0 isppass

ppp pap sent-username ispuser password 0 isppass

!

ip route 0.0.0.0 0.0.0.0 Dialer1

!

dialer-list 1 protocol ip permit

Substitute ispuser and isppass for the PPPoE username and password assigned to you by the ISP. Once configured, Dialer1 becomes your WAN interface.
