FRR 0.6.7_6 OSPF6d No route to kernel routing table after a while

suddi

Hey,
i use FRR 0.6.7_6 to route in a ring topology.
With IPv4 it seems to working properly, but with IPv6 OSPFv3 stops to write some routes to the kernel routing table.

For example, i have only the following entry in the routing table:

2001:X:X:3::2	link#4	UHS	0	16384	lo0

There should be the entry:

2001:X:X:3::/64	link#3	U	0	1500	em2

After i restart the system, it work for a while.
In OSPFv3 the routes are visible (show ipv6 ospf6 route):

*N IA 2001:X:X:3::/64            ::                           em2 00:10:40
 N E1 2001:X:X:3::/64            fe80::92e2:baff:fe5a:cf57    em2 00:10:35

I dont know why it happens after a while?
Could someone give me a hint to solve this problem?

Thank in advance!

UPDATE

It happens only for the transit networks. The stub-ones are working properly. It seems that a timer at the routing table is running out and is not updated via the OSPF-Process.

Pfsense FRR is at 0.6.7_6 with FRR 7.3.1, FRR is at release 7.4 since July, maybe an update of the Pfsense FRR package can help here ?

Hey pete,
thanks for your reply. It seems that there is no newer version in pfsense. In the "package manager" is no update available.

Pfsense FRR is based on this :

https://github.com/FRRouting/frr/releases

we need an updated package from time to time.
