Reloading ospf on rbx-1-6k
During some time,routing was correct. ok, so it's there.

Between rbx-1 and gsw-1 we have a 4x10G which is not used but is still up. The cost on this link is huge so the traffic goes through there only in NUCLEAR disaster.

rbx-1-6k(config)#ipv6 router ospf 16276
rbx-1-6k(config-rtr)#passive-interface Port-channel9
gsw-1-6k(config)#ipv6 router ospf 16276
gsw-1-6k(config-rtr)#passive-interface po9

For now,this link is no longer used on IPv6

Routage is correct actually.

gsw-1-6k#clear ipv6 ospf process
Reset ALL OSPF processes? [no]: yes

We relaunched the OSPF process on gsw-1-6k and set the link routing back. The problem starts again.

interesting:)

Well, we will cut the link, then we will think quietly.
