I did some research and found some possible partial answers but not a complete answer to the following question. If you have a router with multiple direct vanilla FE (non trunked) interfaces on a switch trying to send QOS tagged packets to a wifi bridge several switches away does the trunking in the switched infrastructure mess with the qos tags if no qos is configured on the switches.
Does anyone know this? Does it depend on the switch? We have new 2960's running 12.2 and a few older 2950's running 12.1

Generally, if a Cisco switch's QoS is disabled, packet's ToS is passed as is. If QoS is enabled, by default, switch will reset ToS to zero.

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.

Question 1: What are the OSPF Loop Prevention Mechanisms
In single area, the routers have the Link State Database, having the same LSDB helps the routers to build a loop-free topology.
Now in a multiarea topology, the ABRs are respon...
