I agree with you about your technique but : Why do you want to prevent 0.0.0.0 to be advertized via the iBGP ? I think, if each edge router, advertize his eBGP-learned default route to his iBGP peer, each edge router have 2 default routes and so will prefer the EBGP path. And if the EBGP path is lost, iBGP path is used (and so if other routers are on the same LAN, ICMP redirect is generated pointing to the second edge router). NB : I think that HSRP will desactivate ICMP redirects on the configured interface. And so if u want to use it, u have to reenable it. > 2) I would highly recommend running an IGP such as OSPF on all your > routers.
