Yes, they went in a few weeks ago too :) ( there is one patch outstanding though) current released quagga cannot handle ifindex in the LSA(like BIRD do for /32 masks). This is an old defect in Q. so BIRD is not to blame. > > As far as I understand unnumbered interfaces are those that have > > something like this > > > > interface Loopback0 > > ip address 1.1.1.1/255.255.255.255 > > ! > > interface Tunnel0 > > ip unnumbered Loopback0 > > > > And I have no knowledge about quagga possibilities here, and no such > > configuration in my quagga too. > ... > > Excuse me, but why do you consider /32 prefix as improper ? > > Generally, i consider that network has proper IP prefix if all > interfaces connected to that network share that prefix [*] (i.e. > 192.168.1.10 and 192.168.1.20 in 192.168.1.0/24, or even 192.168.1.10 > and 192.168.1.11 in 192.168.1.10/31). This is usual network setup. Yes, a /32 mask is not a "proper" prefix so you are quite right. What to do with these varies in existing ospf impl. Jocke
