Which two statements are correct about segment routing? (Choose two.)
Segment routing does not require the maintenance of specific adjacencies because it operates by advertising label information within existing protocols like OSPF or IS-IS, eliminating the need for segment routing-specific hello messages or sessions. Label assignments in segment routing can indeed be advertised through OSPF updates, making it more efficient and reducing the overhead associated with maintaining additional protocol-specific adjacencies.
To start with, segment routing is not a protocol in the same way that LDP or RSVP are protocols. There are no segment routing hello messages, no segment routing sessions or adjacencies, and no explicitly signaled segment routing LSPs. Instead, segment routing piggybacks off of IS-IS or OSPF, and advertises label information directly in these protocols.
