Cisco router bandwidth limit and/or manipulation between two sites
Posted on 2008-10-22
I have a situation where I am splitting a DS3 line to 2 sites. The DS3 line comes into my Cisco 3800 router on interface Serial 1/0. From there I have 2 Gigabit Interfaces Gi0/0 and Gi0/1. I have traffic routing for 1 block of IPs to Gi0/0 and another block going to Gi0/1. All that works great. My question is about limiting bandwidth. The link is not a full DS3, we are only supposed to get 10 megs (although speed tests show 35200 kb/s down and 33332 kb/s up). My goal is to guarantee at least 75% of the bandwidth to GI0/0 and the remaining 25% to Gi0/1. If the link is not being used by one interface, the respective interface should be able to use the whole thing. I would still like to use the 10megs for calculation as I am not sure of the longevity of my current speeds.
Thank you -
