Route-map based on bandwidth

[jkca12260]

I have what I believe is a common problem with most techs with multihomed networks, I have two providers that bill on 95th percentile and would like to be able to ensure that we do not receive any billing surprises at the end of the month. The statement I would like to see is the following:

rate-limit output 100000000 2000000 2000000 conform-action transmit exceed-action "net-hop second carrier"

basically put this statement on the interface of one carrier that I want to ensure bandwidth does not exceed 100 meg and if it does the packet is redirected to my second carrier, item in quotes is obviously not allowed. 

Any one have any ideas? Only thing I can think of is to have a rate-limit statement first then do a match-all route-map second to set next-hop, however I don't know the precedence between rate-limit and route-map.

jkca12260,

I am not sure if such a relation exist or if your router will really support the rate-limit command since it is obsolete in some routers and IOS images. I am not sure if this can be done but it will help seeing what IOS and platform you are working with along with what interface as well. A show version will give you the IOS and platform and just post your int info if you don't want to share the entire configuration.

I remember doing this type of thing back when we used the Cisco 7000 series routers, currently we are using some GSR12410's with 12.0.33 IOS on them. Currently we do not have a config thats active on this, we have tested quite a number of configurations but without success.

I think Joseph may have nailed it. Check out the following links from PfR, just double check to see if you platform and IOS supports the feature.

Does not look that works with the GSR series routers, we are using the 12410 currently. Looks like we may have to go to the ASR series to go with pfr if we can't figure this out otherwise.
