the laptop is behind an IP phone and connects to the network okay, picks an IP address from the DHCP server but doesn't pass traffic.. (cant ping any other host on the network including its own gateway apart from only the switch where it is connected).
The MAC address of this host shows in the MAC address table of an upstream switch (which is the gateway) as a STATIC entry and connected to another port (interestingly not the trunk uplink port but another user port). We get the host back to the network by bouncing the port which makes it dynamically learnt and on the right switch.
Any experience with this kind of scenario? what could be causing the same?
Yes indeed. As a stop gap, when this happens I connect to the upstream switch that has the wrong port assignment for the mac address and shut/unshut it to release the mac address. But this happens againin a day or two.

When moving from OSPFv2 to OSPFv3, there are many changes in the format of the LSAs Type, but the most known changes are: IP prefix informations are no longer carried in Type-1 LSA and Type-2 LSA, new LSAs Type 8 and 9 are added to carry these prefixes.
