The correct answer is C. Move one of the uplinks to another ERS 5698TFD in the stack, configure MLT, and group the two uplinks. See the full explanation below for the reasoning.
Question
A customer has a stack of Ethernet Routing Switch (ERS) 5698TFD switches, the uplinks to the network core are via two Gigabit uplink ports from the first ERS 5698TFD in the stack to a single virtual services platform (VSP) 9000. The links are not part of a Multi-Link Trunk (MLT) and spanning tree is running. This results in one of the links always being blocked and recovery time unacceptably long when the active uplink fails. They need to have both links active to increase the bandwidth to the core, and at the same time provide better redundancy. What is the preferred Avaya solution for the customer?
Options
- AMove only of the uplink to another ERS 5698TFD in the stack and disable spanning-tree on both uplinks.
- BMove one of the uplinks to another ERS 5698TFD in the stack and enable Equal Cost Multi- Path (ECMP)
- CMove one of the uplinks to another ERS 5698TFD in the stack, configure MLT, and group the two uplinks
- DMove one of the uplinks to another ERS 5698TFD in the stack, and ensure that the uplinks terminate on
