Hello Adhitya,

this HWIC 2FE should provide two routed ports

so you just need to configure the two ports

int fas0/0

desc first link

ip address x.x.x.x 255.255.255.x

no shut

int f0/0

desc first link

ip address y.y.y.y 255.255.255.y

no shut

It is wise to add a shaper

policy-map shape_out1

class class-default

shape average 3900000

policy-map shape_out2

class class-default

shape average 3900000

int f0/0

service out shape_out1

int f0/1

service out shape_out2

other aspects may be needed but you haven't provided much detail

Hope to help

When you bandwidth is limited by the ISP, you do not need to configure any service policy on your router.

Hello Adhityua,

the configuration I have provided should be enough for your needs.

a link to QoS documentation in 12.4 mainline IOS


I think that shaping in your case is recommended because your physical interfaces are FE with 100 Mbps capabilities but circuit speed is only 4 Mbps.

The router without shaping tries to send packets as fast as possible that is at line speed and then to stay silent.

Hope to help
