Bandwidth restriction through ACL on Router 2600 series

[admin_2]

Hello,

we have 2 mbps internet leased line. We are destributing it into 2 different sagment. can we restrict only internet bandwidth by using access list ?

There is no easy way of doing this. You will need to configure QoS based on what traffic needs what kind of servicing. For configuring QoS on cisco routers, you could refer to the documentation at http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fqos_c/index.htm

you didn't say what the 2600's config is, so let's presume it is a 2621 with an E1 WAN wic. Let's further presume that you'd like to allow each of the two subnets to get 50 percent of the internet connection for each ethernet segment.

Create classification policies for each segment's IP addresses, then map that into policy maps that restrict each of the queues bandwidth.

Alternately, you can use traffic policing to do the same thing instead of CBWFQ still clasifying by IP addresses of that ethernet segment. Please note that classifying by IP address is a bit more strenuous on the router than protocol number.
