NEW QUESTION # 12
Whatare two ways in which an EVPN-signaled VXLAN is different from a multicast-signaled VXLAN?
(Choose two.)

  • A. An EVPN-signaled VXLAN is less resource intensive.
  • B. An EVPN-signaled VXLAN features slower and more complete convergence.
  • C. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using IS-IS.
  • D. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP.

Answer: A,D

Explanation:
* Multicast-Signaled VXLAN:
* In traditional multicast-signaled VXLAN, VTEPs (VXLAN Tunnel Endpoints) use multicast to flood and learn about remote VTEPs. This method relies on multicast in the underlay network to distribute BUM (Broadcast, Unknown unicast, and Multicast) traffic.
* This approach can be resource-intensive due to the need for multicast group management and increased network traffic, especially in large deployments.
* EVPN-Signaled VXLAN:
* EVPN-signaled VXLAN uses BGP (Border Gateway Protocol) to signal the presence of VTEPs and distribute MAC address information. BGP is used for VTEP autodiscovery and the distribution of endpoint information.
* This method is more efficient because it reduces the reliance on multicast, instead using BGP control-plane signaling to handle VTEP discovery and MAC learning, which reduces the overhead on the network and improves scalability.
* Correct Statements:
* B. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP:This is correct because EVPN uses BGP for VTEP autodiscovery, making it more efficient and scalable compared to multicast-based methods.
* C. An EVPN-signaled VXLAN is less resource-intensive:This is correct because it eliminates the need for multicast flooding in the underlay, instead using BGP for signaling, which is less demanding on network resources.
* Incorrect Statements:
* A. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using IS-IS:This is incorrect because EVPN relies on BGP, not IS-IS, for VTEP discovery and signaling.
* D. An EVPN-signaled VXLAN features slower and more complete convergence:This is incorrect; EVPN with BGP typically provides faster convergence due to its use of a control plane rather than relying on data plane learning.
Data Center References:
* EVPN-VXLAN is widely adopted in modern data center designs due to its scalability, efficiency, and reduced resource consumption compared to multicast-based VXLAN solutions. It leverages the strengths of BGP for control-plane-driven operations, resulting in more efficient and scalable networks.


NEW QUESTION # 13
You are asked to interconnect two of your company's data centers across an IP backbone. Both data centers require Layer 2 and Layer 3 connectivity. In this scenario, which three actions would accomplish this task?
(Choose three.)

  • A. Ensure there is a full mesh of VTEPs between all leaf nodes within data centers.
  • B. Advertise Type 2 EVPN routes across the DCI.
  • C. Ensure there is a full mesh of VTEPs between all spine nodes within both data centers.
  • D. Ensure border leaf nodes in each data center can exchange EVPN routes.
  • E. Advertise Type 5 EVPN routes across the DCI.

Answer: B,D,E

Explanation:
* Layer 2 and Layer 3 Connectivity Requirements:
* To interconnect two data centers across an IP backbone with both Layer 2 (L2) and Layer 3 (L3) connectivity, EVPN-VXLAN (Ethernet VPN with Virtual Extensible LAN) is the ideal solution.
EVPN supports L2 VPNs while also enabling L3 connectivity across multiple locations.
* Necessary EVPN Route Types:
* Type 2 EVPN Routes:These routes are used to advertise MAC addresses for Layer 2 connectivity. They are essential for enabling seamless L2 communication across data centers.
* Type 5 EVPN Routes:These routes are necessary for advertising IP prefixes for Layer 3 connectivity between data centers. They enable the exchange of L3 information across the IP backbone, ensuring routed traffic can reach its destination.
* Border Leaf Nodes:
* Border Leaf Nodes:Ensuring that the border leaf nodes (the entry and exit points for traffic between data centers) can exchange EVPN routes is critical for the correct dissemination of both L2 and L3 information across the data centers.
Conclusion:
* Option A:Correct-Type 2 EVPN routes are required for Layer 2 MAC address learning and communication across the DCI (Data Center Interconnect).
* Option B:Correct-Border leaf nodes need to exchange EVPN routes to maintain connectivity between data centers.
* Option D:Correct-Type 5 EVPN routes are essential for Layer 3 connectivity across the DCI.
OptionsCandEare incorrect because they refer to establishing full mesh VTEPs (VXLAN Tunnel Endpoints) across all spine or leaf nodes, which is unnecessary for the scenario provided. The focus should be on border leaf nodes and appropriate route advertisements for L2 and L3 connectivity.


NEW QUESTION # 14
You want to convert an MX Series router from a VXLAN Layer 2 gateway to a VXLAN Layer 3 gateway for VNI 100. You have already configured an IRB interface. In this scenario, which command would you use to accomplish this task?

  • A. set vlans VLAN-100 13-interface irb.100
  • B. set bridge-domains VLAN-100 routing-interface irb.100
  • C. set protocols ospf area 0.0.0.0 interface irb.100 passive
  • D. set protocols isis interface irb.100 passive

Answer: B

Explanation:
* Scenario Overview:
* Converting an MX Series router from a VXLAN Layer 2 gateway to a VXLAN Layer 3 gateway involves transitioning the router's functionality from simply bridging traffic within a VXLAN segment to routing traffic between different segments.
* Key Configuration Requirement:
* IRB (Integrated Routing and Bridging) Interface:An IRB interface allows for both Layer 2 switching and Layer 3 routing. To enable routing for a specific VNI (VXLAN Network Identifier), the IRB interface must be associated with the routing function in the corresponding bridge domain.
* Correct Command:
* C. set bridge-domains VLAN-100 routing-interface irb.100:This command correctly binds the IRB interface to the bridge domain, enabling Layer 3 routing functionality within the VXLAN for VNI 100. This effectively transitions the device from operating solely as a Layer 2 gateway to a Layer 3 gateway.
Data Center References:
* This configuration step is essential when converting a Layer 2 VXLAN gateway to a Layer 3 gateway, enabling the MX Series router to route between VXLAN segments.
