set up different bandwidth on LAN interfaces of router

i have set up a small lab for testing optimization of certain applications...i have connected two routers with gigabit port to be utilized as WAN connections..since gigabit port supports 1000mbps, but i want to have only 1Mbps or 2 Mbps i.e less than 1000Mbps between both routers...means i want to make LAN port as WAN port..

how to achieve this bandwidth...kindly provide the configuration to achieve this..

Re: set up different bandwidth on LAN interfaces of router

HI,

Gigabit capacity of "1000mbps" is just the speed of the interface.

This "1000mbps" is not related to the Bandwidth incoming / outgoing.

Do provide more details on the same.

Pls Rate if HELPS

Best Regards,

Re: set up different bandwidth on LAN interfaces of router

u may change the bandwidth parameter on the interface by getting in to interface config mode & giving the command "bandwidth xyz" in kbps.

Pls note that the bandwidth command is used for metric calculations only, it doesnt change the interface performance.

Another alternative is, since u r plannig to simulate WAN on router interfaces. Simply vary the metric of interface to the respective routing protocol used, instead of varying BW.

Re: set up different bandwidth on LAN interfaces of router

If you want to restrict the fastethernet speed to say one or 2 mbps for your simulation, i would suggest you configure Policing or shaping

policy-map wan-restrict-out

class class-default

police CIR 200000 conform-action-transmit exceed-action -drop

interface fastether 0/1

service-policy output wan-restrict-out

configure this on both the sides and you should be good to go
