Hi Alexander, here is our feedback of your submission. Please take a look and fix all incorrect configurations. 1.1a Good division into subnetworks. Incorrect gateway for staff members.--->(done) Discuss how trunk ports enable across VLAN communication. 1.1b The spanning tree before configuration is not a spanning tree. Root switch is correct. Incorrectly talk about how all traffic should pass through the root switch. Bad idea to set the cost of ZENT-NORD to 4. you aim to force traffic through the root bridge. --->(done) Their root bridge (SACH) has 2 blocking ports… 1.2 Traceroute seems correct. 1.3 Not all weights are displayed. Wrongly assigned values in some cases. Load balancing on land will work. Load balancing through submarine cables is not configured correctly. 1.4 iBGP sessions establish a full-mesh will all routers. One session state is “never” --->(unclear) Good explanation of the command. Does not explain why we want to use the lo interface.
