Thanks for the questions, good for me to think about it some more. Short response: I don't think it is the FRR config, but the routes received that are crashing it or ospf6d has some other issue.

Personally, I always put a 172.17.x.x IP on my lo0 and then advertise that into my network. I don't make it part of the router config, but I wanted a 'test device' to boot ospf6d and see it crash. Also, the docs on FRR have an lo0. I do advertise my 172.17.x.x IP on the loobpback: This is how I verify OSPF is up -- the IPwill ping from other devices on the network when OSPF is up. For IPv6, I put a whole /64 on the lo0. So many IPs in v6. :) >> *** LOGS *** >> >> 2019/10/10 23:19:31 OSPF6: Scheduling cxl1 for sso >> 2019/10/10 23:19:31 OSPF6: SPF: Scheduled in 0 msec >> 2019/10/10 23:19:31 OSPF6: SPF processing: # Areas: 1, SPF runtime: 0 >> sec 5 usec, Reason: L+ >> >> 2019/10/10 23:19:31 OSPF6: Scheduling cxl2 for sso >> 2019/10/10 23:19:31 OSPF6: SPF: Scheduled in 50 msec >> 2019/10/10 23:19:31 OSPF6: Scheduling cxl3 for sso >> 2019/10/10 23:19:31 OSPF6: Neighbor state change 172.17.24.25%cxl3: >> [Down]->[Init] (HelloReceived) >> 2019/10/10 23:19:31 OSPF6: Neighbor state change 172.17.24.25%cxl3: >> [Init]->[ExStart] (2-WayReceived) >> 2019/10/10 23:19:31 OSPF6: Neighbor state change 172.17.24.25%cxl3: >> [ExStart]->[ExChange] (NegotiationDone) >> 2019/10/10 23:19:31 OSPF6: Neighbor state change 172.17.24.25%cxl3: >> [ExChange]->[Loading] (ExchangeDone) >> 2019/10/10 23:19:31 OSPF6: SPF processing: # Areas: 1, SPF runtime: 0 >> sec 109 usec, Reason: R+, R-, L+ >> >> 2019/10/10 23:19:31 OSPF6: SPF: Scheduled in 83 msec >> 2019/10/10 23:19:31 OSPF6: SPF processing: # Areas: 1, SPF runtime: 0 >> sec 116 usec, Reason: R+, N+, L+ >> >> 2019/10/10 23:19:33 OSPF6: Neighbor state change 10.8.254.122%cxl1: >> [Down]->[Init] (HelloReceived) >> 2019/10/10 23:19:33 OSPF6: Neighbor state change 10.8.254.122%cxl1: >> [Init]->[ExStart] (2-WayReceived) >> 2019/10/10 23:19:33 OSPF6: Neighbor state change 10.8.254.122%cxl1: >> [ExStart]->[ExChange] (NegotiationDone) >> 2019/10/10 23:19:33 OSPF6: Neighbor state change 10.8.254.122%cxl1: >> [ExChange]->[Loading] (ExchangeDone) >> 2019/10/10 23:19:33 OSPF6: SPF: Scheduled in 0 msec >> 2019/10/10 23:19:33 OSPF6: SPF processing: # Areas: 1, SPF runtime: 0 >> sec 99 usec, Reason: R+, R- >> >> 2019/10/10 23:19:36 OSPF6: Neighbor state change 172.17.24.25%cxl3: >> [Loading]->[Full] (LoadingDone) >> 2019/10/10 23:19:36 OSPF6: SPF: Scheduled in 0 msec >> 2019/10/10 23:19:31 ZEBRA: client 32 says hello and bids fair to >> announce only ospf6 routes vrf=0 >> 2019/10/10 23:19:38 ZEBRA: [EC 4043309117] Client 'ospf6' encountered an >> error and is shutting down. >> 2019/10/10 23:19:38 ZEBRA: release_daemon_table_chunks: Released 0 table >> chunks >> 2019/10/10 23:19:38 ZEBRA: release_daemon_label_chunks: Released 0 label >> chunks >> 2019/10/10 23:19:39 ZEBRA: client 32 disconnected. 100 ospf6 routes >> removed from the rib >> >> *** CRASH *** > Zebra process crashes after the ospf6 process has encountered some error > and shut down or are you indicatong that the OSPF6D process has crashed?
