Hi list I'm having issues with a Debian 10 based router running BIRD 2.0.7.
On the router I have several interfaces where OSPFv3 is active. All good. Besides those interfaces, i also have a dummy interface named loopback0. Config example: area 0 { interface "ens*" { type ptp; cost 1; hello 5; }; interface "loopback0" { stub; cost 1; }; }; The ens interfaces work just fine. However, the /128 I have configured on the loopback0 interfaces is constantly not being picked up by BIRD. It's like BIRD completely ignores the existence of that interface. It simply won't announce that /128 out to its peers connected through the ens interfaces. If i change the /128 to a /127 instead, the prefix is advertised by bird. Any clues as to what gives this kinda unexpected (to me) behavior? Why wouldn't BIRD recognize a /128? I'm used to both Cisco and Juniper and have not seen this behavior before. All I'm trying to do is use my loopback for establishing an iBGP mesh - basic use case, i believe :) Thanks! Best Regards Anders Hansen
