sure, "show ip cef 0.0.0.0 0.0.0.0" should show both paths, and "per-destination sharing". see http://www.cisco.com/en/US/products/hw/modules/ps2033/prod_technical_ref erence09186a00800afeb7.html > There is still one thing I don't understand: > >> Make sure to mesh the two eBGP speakers via iBGP. >> Guess you want to disable icmp redirects on the interface, >> best link those two eBGP speakers with a dedicated link to >> prevent blackholes.. > > ... disable icmp redirects on which interface exactly? on the /27 interface linking all the routers together. Otherwise it could happen that a node follows the default-route to A, but if A doesn't know the destination via eBGP, but via iBGP from B, it will send a redirect to the node. This could be undesireable.. oli _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
