One way to do this is to use BGP. This load balances ok if you have two Teir 1 providers, but will not load balance otherwise. The advantage is this is the only way to provide uptime if one of the ISPs goes down unless you do NAT on the Cisco 2514. You may have problems running BGP on a 2514, but I think this will work as long as you only get routes to connect hosts from each ISP, and then set the default route to the least used link.
Hope this helps. Eric Schroeder [EMAIL PROTECTED] 12/05/2001 09:44 PM To: [EMAIL PROTECTED] cc: Subject: Source-sensitive Routing ... Dear memebers, I have the following network configuration: -------------------------------------------------------- | | | 10.x.x.x | | | -------------------------------------------------------- | | ---------------------- | Dual Homed Gateway | ---------------------- | | --------+------------- | Cisco 2514 Dual LAN | | Router | | | | wan1 wan2 | ---+------------+----- | | | | | | ISP1 | | ISP2 ======================================== + + + INTERNET + + + ======================================== All our clients in the private network address (10.x.x.x). Using the Proxy Server at Dual homed gateway, these clients get connected to Internet using ISP1 link. Recently we have received another link for Internet connection from ISP2. Hence we are planning to route some of the clients of private network address(10.x.x.x) through ISP1 link and the remaining ones through ISP2 link, using Cisco 2514 Dual LAN Router running IOS software 11.0. After reading the Cisco documents, I came to know that this is possible through SOURCE-SENSITIVE routing at the Router. I want to know the followings: 1. Is there any alternative way(s) to achieve this goal using the same router having two WAN interfaces? 2. What are the security issues related to SOURCE-SENSITIVE routing ? Waiting for your suggestions .... Rakesh Kumar ============ -------------------------------------------------
