PD numberThe workaround is realy ugly for us because we need jumbo an as this is solved in build after 18.104.22.168, I decided to update to XOS 15.x.x.x.
Severity 3-Wrong Behavior
Closed / Verified
IP:OSPFv3 / App:Common / Existing Feature
In a jumbo frame environment, an OSPFv3 neighbor gets stuck at EX_START.
Configure ip-mtu size BEFORE configuring the first IPv6 address for the vlan. (In order to do this, IPv4 address must be configured for the vlan before configuring ip-mtu size even if you intend to use the switch for IPv6 only environment.)
