What are two functions of MPLS Layer 3 VPNs? (Choose two.)
What are two functions of MPLS Layer 3 VPNs? (Choose two.)
MPLS Layer 3 VPNs have distinct functions that include encapsulating customer traffic in a VPN label when it is forwarded within the MPLS network. Additionally, BGP (Border Gateway Protocol) is used for signaling customer VPNv4 routes between Provider Edge (PE) nodes. These functions enable efficient and scalable routing of multiple customer VPNs over a shared network infrastructure.
The given answer is correct
C is OK. D - it should be MBGP not BGP.
The given answer looks good.
The given answer is correct
C & D are correct
According to this doc B could be correct: https://www.cisco.com/c/en/us/td/docs/routers/asr920/configuration/guide/segment-routing/17-1-1/b-segment-routing-17-1-asr920/b-segment-routing-17-1-asr920_chapter_00.pdf If D isn't a type, then the answer is B and C
I think the answer is B and C. D should be MPBGP. According to this document: Segment routing is a method of forwarding packets on the network based on the source routing paradigm. Segment routing leverages other Interior Gateway Protocols such as IS-IS, OSPF, and MPLS for efficient and flexible forwarding. Segment routing is a faster and a more efficient way of forwarding traffic in the MPLS core network.A router in aSegment Routing network can select either an explicit path or a default Interior GatewayProtocol (IGP) shortest path. Segments represent subpaths that a router can combine to form a complete route to a network destination. Each segment has an identifier (Segment Identifier) that is distributed throughout the network using new IGP extensions. Each router (node) and each link (adjacency) has an associated segment identifier (SID). Node segment identifiers are globally unique and represent the shortest path to a router as determined by the IGP.
Also E it tru, but it is layer 2. If D is a typo, which I don't think it is, than B and C should be correct, however "B" is just MPLS label, layer 2.5 and not layer 3.
Correction B is layer 3. Answer = B, C. MBGP and not BGP is used for answer D.
Correction B is layer 3. Answer = B, C. MBGP and not BGP is used for answer D.
