Title: RE: [FW-1] Nokia & ISP Load Balance

addressing the BGP issue only:   static routes would work fine. If you really want BGP, you will need to point your bgp neighbors to a virtual address (loop 0). The reason is is that BGP is a path vector routing protocol. If you have 2 paths, bgp will pick one that it lultimately likes over the other according to path metrics. In order to trick BGP into doing a dynamic load balance situation you need to use the loop implementation. Sam Hilabi is a great BGP book. This is mentioned in there. ----- Original Message ----- From: Dan Hitchcock To: [EMAIL PROTECTED] Sent: Thursday, May 02, 2002 10:32 AM Subject: Re: [FW-1] Nokia & ISP Load Balance The main problem you will encounter is that your VRRP traffic would have to pass over the internet for the boxes to detect each others' failures on the serial interface.  In other words, no, it won't work (at least, not how you hope :) A pair of routers running HSRP and iBGP/eBGP will work, as would a pair of LinkProofs (need 2 of them to maintain true HA at all points in your environment) or similar load-balancing device.

The majority of these solutions use the traditional ISP connection, router, dual firewall setup. I want to develop a solution using dual 2mb ISP connections that are load balanced. From the information I have been able to pull off the net and also reading through the archives of mailing lists, the normal way to do this is using two Cisco routers configured with iBGP and eBGP and dual firewalls. Fair enough. But I have been looking at the Nokia solutions recently, and I like the idea of being able to clunk my Firewall directly into the X21 connection from my leased line modem thus removing the need for the standard internet router... What I am wondering is, if it is possible to setup two Nokia 650's each connected directly to a different 2mb link and provide load balancing and HA between them for inbound and outbound traffic... What I need to know is (a) Is this possible. (b) Is it a good idea. (c) Anywhere I might find sample diagrams / configs / information about doing this.... My attemp at a diagram below will hopefully illustrate what I am talking about.        2Mb Conneciton 1               2mb Connection 2                   !                                         !                   !                                         !                   !                                         !         ******************                    ****************         *  Nokia 650   *                     * Nokia 650 *         ******************                    ****************                   !                                         !                   !                                         !                   !                                         !     ====================================                     Corporate LAN     ==================================== I would be grateful for any pointers or suggestions about how I could achieve load balancing across the two links.
