Question Image

R1 is sending data traffic to R6 using the same SRGB range as the other routers in the topology, but it is also using a non-default SRLB range. Which two configuration tasks must the engineer complete to enable normal SRGB and SRLB operations on this network?

Choose two
  • A Configure router R2 with adjacency SID 4002 to enable it to reach R4.
  • B Configure an adjacency SID from SRLB range 1002 to 6005.
  • C Set the SRGB range to 1002 to 6005.
  • D Configure router R1 with adjacency SID 1003 to enable it to reach R2.
  • E Set the default SRGB range to 16000 to 23999.
Explanation

The SRGB must be the common 16000–23999 range so node-SID indexes resolve consistently throughout the domain. Adjacency SIDs are locally significant segments and must be allocated from the configured SRLB; therefore, the adjacency-SID label range must cover 1002–6005. The specified per-router adjacency alternatives use labels belonging to different outgoing adjacencies.
