Hi Juniper Guru's. I Have a question regarding the best way to generate a default route in BGP.
The topology is as below. Rtr1 and rtr2 both have a full EBGP feed from different providers (incl Default route) rtr1 and rtr2 have an IBGP session and exchange full tables. There's also IBGP sessions between: rtr1- fw1 rtr1- fw2 rtr2- fw1 rtr2- fw2 On these sessions we only announce a default route from the routers to Firewalls. -------- ------- | rtr1 | | rtr2 | -------- -------- -------- ------- | fw1 | | fw2 | -------- -------- The challenge I have is a good way of originating a default route. For example rtr1 - fw1 is most preferred path (done using local prefs). But I'm preferring the ISP on rtr2 (localpref). as a result rtr1 is not sending the default route to fw1, since its best route was learned through IBGP from rtr2 (unless I'd set it up as route-reflector). Also I don't want the ASpath original ASpath to show up in the default. It should just be the "I" Locally originated, not the AS of my provider in there. I *do* need the default on both routers as well (I have a few remote sites using same AS, so rely on default to get there, not interested in allow-as-in etc now). So I can't put in a static pointing to my iso, cause I want to make sure it fails over correctly if that connections becomes unavailable. I'm guessing that also eliminates the " no-install discard " option as it will over ride the default route I learned from my ISP and/or other border router. So, wondering what's the best way to do this? any recommendations? tips? This is for both IPv4 and IPv6 Thanks, George _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
