Cisco PPPoE Router with Managed Modem

[TONY SMITH]

Hi,

The scenario will be a Cisco router (not sure what type yet), connecting via PPPoE to a separate DSL modem.   The modem can be managed via IP on the same interface as used for PPPoE.    Is that a supported configuration with a Cisco router, ie able to apply an IP address to the WAN interface as well as the PPPoE configuration?

Ta in advance,   Tony S

Hello Tony,

Yes, that is a supported configuration. On a Cisco router, an Ethernet interface can be set up both for its own IP address, and run a PPPoE client at the same time.

interface FastEthernet0/0
 ip address 192.168.255.1 255.255.255.0
 pppoe-client dial-pool-number 1
 no shutdown
!
interface Dialer0
 encapsulation ppp
 dialer pool 1
 mtu 1492
 ip address negotiated
 ip tcp adjust-mss 1452
 ppp pap sent-username SomeLogin password SomePassword
 ppp chap hostname SomeLogin
 ppp chap password SomePassword
 ! ... other config like NAT, etc.
!
ip route 0.0.0.0 0.0.0.0 Dialer0

Best regards,
Peter
