Can 1.1.1.1 and 2.2.2.2 reach each other? That is, do they have routes to each other (on 1.1.1.1 and 2.2.2.2 specifically)? If their interfaces are on the same subnet, that wasn't an issue when you weren't using loopback. But now it may be. If so, add statics for each of the loopbacks... or put them in an IGP. /a _______________________________________________ Quagga-users mailing list [email protected] https://lists.quagga.net/mailman/listinfo/quagga-users
