Which of the following steps is NOT required when configuring IS-IS to support Segment Routing?
When configuring IS-IS to support Segment Routing, MPLS label ranges reserved for Segment Routing and the Segment Routing Global Block range need to be specified. Additionally, the flooding scope of Segment Routing information must be set. However, enabling interfaces used for Segment Routing under the MPLS context is not a required step.
The correct answer is B, the required configuration for ISIS to support SR 1. configure MPLS label values that will be reserved for SR 2. enabling segment routing context and configuring the local segment routing Global block (SRGB) 3. Selecting the flooding scope of segment routing information 4. assign the node side to the router (system interface or loopback)
You do not have to add SR interfaces under MPLS
