What I got on my mind was an eBGP session to stub site /single homed customer.
Hi Adam, "Single homed stub site" is not a configuration option in any BGP setup I'm aware of, so how would the router select RPF as the default for a single-homed stub site? On the other hand, a router can usually make a determination about "routing protocol is active on this interface." That's not true of a few BGP-only configurations, but it's true everywhere else in the network interior. Any interface where the routing is 100% static is by definition a single-homed stub. And for the purposes of this discussion, radius, tacacs and dhcp are not routing protocols; a radius-assigned route is static on the interface to which it is assigned. Hence RPF could safely enable itself by default there. Regards, Bill Herrin -- William D. Herrin ................ herrin@dirtside.com bill@herrin.us 3005 Crane Dr. ......................
