Cisco Systems OL-6426-02 manual Configure the Fast Ethernet WAN Interfaces, Request-dialin

Chapter 3 Configuring PPP over Ethernet with NAT

Configure the Fast Ethernet WAN Interfaces

	Command or Action	Purpose
Step 3
	request-dialin	Creates a request-dialin VPDN subgroup,
		indicating the dialing direction, and initiates the
	Example:	tunnel.
	Router(config-vpdn-grp)# request-dialin
	Router(config-vpdn-grp)#
Step 4
	initiate to ip ip-address	Specifies the address to which requests are
		tunneled.
	Example:	For details about this command and additional
	Router(config-vpdn-grp)# initiate to	parameters that can be set, see the Cisco IOS Dial
	192.168.1.1	Technologies Command Reference.
	Router(config-vpdn-grp)#
Step 5
	protocol {l2f l2tp pppoe any}	Specifies the type of sessions the VPDN subgroup
		can establish.
	Example:
	Router(config-vpdn-grp)# protocol pppoe
	Router(config-vpdn-grp)#
Step 6
	exit	Exits VPDN group configuration.
	Example:
	Router(config-vpdn-grp)# exit
	Router(config-vpdn)#
Step 7
	exit	Exits VPDN configuration, returning to global
		configuration mode.
	Example:
	Router(config-vpdn)# exit
	Router(config)#

Configure the Fast Ethernet WAN Interfaces

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

Note 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%.
