ISP failover

Hi,

I have two different links from different ISPs, each is terminated on different cisco 2600 routers and used for different services (one for webservices and the other for just internet browsing). However, I want to configure the routers in such a way that the webservices link would failover to the internet browsing router whenever the link is down.

How can I go about this?.

BGP is the best way to go about this.

Hi,

My network is for a private organisation and I cannot be allowed to exchange BGP routes with my service providers.

Is there any other alternative and can i get urls of materials for this?.

Hi

You can use HSRP in your router, and also use higher admin distance static route, this will solve your problem,

if you are not sure , you can send me network diagram along with ip address, i will send you configuration file back.

Re: ISP failover

HSRP will not work. What happens if there is a routing problem in the ISP? Again look at BGP, it does not matter that you are a private organization.

Can you help with the BGP configurations or url materials?.

Re: ISP failover

BGP is not for the timid. I would suggest hiring a consultant. To feed your brain, search BGP on Cisco.com or Google.
