Why would an engineer select this method of bundling several ports together to form a single logical channel? List 3. 2. Create a logical port-channel between the 2 switches in LAB2 using LACP as the protocol. Spanning tree is blocking one of the ports allowing only a single path back to the root, thus eliminating a possible loop. What are the commands to accomplish this connectivity? What command verifies the channel is created and in use? ( Both links should become active )

- 12. Consider the network shown below with the current measured delays between two nodes. A B 3 5 8 E F a. List all possible simple paths between C and D; simple paths are those that do not repeat a node (i.e., no loops). b. Which path provides the shortest delay?Computer Science This problem illustrates some of the difficulties facing network planners when they have to use OADMs that are constrained in what channels they can add and drop. Consider a four-node linear network with nodes A, B, C, and D in that order. We have three wavelengths lambda-1, lambda-2, and lambda-3 available. The OADMs given to us can drop two fixed channels i.e., we can put OADMs that drop either (lambda-1, lambda-2), or (lambda-2, lambda-3), or (lambda-1, lambda-3). Now consider the situation where we need to set up the following light paths – AB, BC, CD, AC, and BD. A) What OADMs would you deploy at each node? B) At a later point, the light path traffic changes and we need to replace light paths AC and BD with AD and BC. What changed would you have to make in order to support the new traffic.Help me understand the distinction between distance vectors, link state vectors, and path vector routing by providing an example.
