When is Trunking applicable and when is IPMP preferred?
Trunking: Layer II IPMP: Layer III Trunking is a link level industry standard that every switch vendor must implement. Trunking has automatic inbound load-balancing, as provided by the switch, whereas IPMP receives on a single link unless you create multiple logical IP addresses to force load balancing to happen. On the other hand, IP MP provides failover across switches, so there is an additional layer of redundancy: works across various network adapters to ensure switch is not single point of failure.
