I just upgraded from FreeBSD 11 to 12 and upgrade from quagga to FRR at
the same time. I've tried frr6 and frr7 and get the same errors.
bgpd and ospfd work fine, but ospf6 doesn't work. Not sure what I'm
going wrong.
If I commend out all the interfaces EXCEPT lo0, ospf6d does not crash.
router ospf6
ospf6 router-id 172.17.18.98
redistribute connected route-map MONKEY-ospf6
redistribute static route-map MONKEY-AND-MORE-ospf6
!interface cxl1 area 0.0.0.0
!interface cxl2 area 0.0.0.0
!interface cxl3 area 0.0.0.0
interface lo0 area 0.0.0.0
As soon as I get routes from my network, ospf6d tanks.
Any thoughts?
Here is the output from zebra and ospf6.
