BSpecifying the flex-algo instance ID as an additional TE constraint for an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.

CConfiguring and applying a VRF import policy to a VPRN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.

DConfiguring and applying a VSI import policy to an EVPN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.

Show Suggested Answer

Suggested Answer: D

The data is transparently carried from end to end: This statement is not true, MPLS does not provide data transparency, which means that the data is not carried unmodified from end to end. MPLS uses labels to forward data, so the original IP packets are encapsulated in new MPLS packets, and the original IP headers are not visible at the egress LSR.

Wait, are we sure this question isn't written by a bunch of flex-algo enthusiasts trying to trick us? I bet the answer is actually 'all of the above' just to keep us on our toes!

Hmm, this is a tricky one. I'm going to have to think about it a bit more, but my initial instinct is that A is the correct answer.

I'm pretty sure B is the right choice. Specifying the flex-algo instance ID as a TE constraint for an SR-TE LSP is a valid way to steer traffic into a flex-algo segment-routing tunnel.

User 1: I think B is correct too. It makes sense to specify the flex-algo instance ID as a TE constraint for an SR-TE LSP.

You're right, I overlooked that detail. Option D seems to be the one that is not a valid option.

I disagree, option C is valid because it specifies enabling sr-is-is or sr-ospf tunnel type for the service.

Option C seems to be the correct answer here. Configuring a VRF import policy and enabling the sr-is-is or sr-ospf tunnel type is not a valid way to steer traffic into a flex-algo segment-routing tunnel.
