Cisco Systems OL-6426-02 Benutzerhandbuch

In this scenario, the PPPoE client (your Cisco router) communicates over a 10/100-Mbps Ethernet 
interface on both the inside and the outside. 

The Cisco 1800 series integrated services fixed-configuration routers have a hardware limitation on the 
Fast Ethernet ports FE0 and FE1. In half-duplex mode, when traffic reaches or exceeds 100% capacity 
(equal to or greater than 5 Mbps in each direction), the interface experiences excessive collisions and 
resets every second. To avoid this problem, you must limit the traffic capacity to less than 100%.

Router(config-vpdn-grp)# request-dialin

Router(config-vpdn-grp)# 

Creates a request-dialin VPDN subgroup, 
indicating the dialing direction, and initiates the 
tunnel.

initiate to ip ip-address

Router(config-vpdn-grp)# initiate to 

Router(config-vpdn-grp)# 

Specifies the address to which requests are 
tunneled.

For details about this command and additional 
parameters that can be set, see the

protocol {l2f | l2tp | pppoe | any}

Router(config-vpdn-grp)# protocol pppoe

Router(config-vpdn-grp)# 

Specifies the type of sessions the VPDN subgroup 
can establish.

Router(config-vpdn-grp)# exit

Router(config-vpdn)# 

Exits VPDN group configuration.

Router(config-vpdn)# exit

Router(config)# 

Exits VPDN configuration, returning to global 
configuration mode.
