Question 1

Refer to the exhibit.

What type of route is shown?

AType 3 host route from external VTEP

BType 2 host route from another VTEP

CType 3 host route from another VTEP

DType 5 host route from another VTEP

Answer : B

The exhibit shows a BGP EVPN route in a VXLAN environment. The route type can be determined based on the details provided. Type 2 routes in BGP EVPN are used to advertise MAC address reachability information between VTEPs (Virtual Tunnel End Points). The exhibit indicates a host route from another VTEP, which corresponds to a Type 2 route.

Question 2

SIMULATION

Configure the system to meet these requirements.

. Configure R1 with AS 1.

. R1 must use a static neighbor assignment for BGP peering.

. R1 needs to redistribute all current and future connected IPv4 routes.

All the required BGP configurations have already been completed on R2.

R2 resides in BGP AS 2.

Asee the explanation for all step by step solution with all explanation

Answer : A

Here is the step-by-step configuration for R1:

Enter BGP Configuration Mode:

R1# configure terminal

R1(config)# router bgp 1

Configure the BGP Neighbor:

R1(config-router)# neighbor 10.10.12.2 remote-as 2

Redistribute Connected Routes into BGP:

R1(config-router)# redistribute connected

Exit BGP Configuration Mode and Save the Configuration:

R1(config-router)# end

R1# write memory

Comprehensive Detailed Step by Step Explanation with Reference:

Enter BGP Configuration Mode:

To configure BGP on R1, you need to enter global configuration mode and then enter BGP configuration mode with the AS number. Since R1 is in AS 1, you use the command router bgp 1.

Configure the BGP Neighbor:

BGP neighbors must be manually specified. In this case, R1's neighbor is R2, which has an IP address of 10.10.12.2 and resides in AS 2. The command neighbor 10.10.12.2 remote-as 2 establishes this relationship.

Redistribute Connected Routes into BGP:

To ensure that all connected routes on R1 are advertised via BGP, you use the redistribute connected command. This ensures that any connected IPv4 routes are redistributed into BGP, meeting the requirement to advertise current and future connected routes.

Exit BGP Configuration Mode and Save the Configuration:

Once the configuration is complete, you exit BGP configuration mode by typing end and then save the configuration with the write memory command. This ensures that the changes persist after a reboot.

Question 5

An administrator for a service provider uses this command on a switch:

What is the result of running the command?

AMaps the VLAN traffic that a CVLAN identifies to a VNI on a VTEP

BMaps the VLAN traffic that a TPID identifies to a VNI on a VTEP

CMaps the VLAN traffic that an SVLAN identifies to a VNI on a VTEP

Answer : C

The command interface vxlan vtep-stacking followed by map vni 10010 vlan 100 maps the VLAN traffic that an SVLAN identifies to a VNI on a VTEP. In this context, SVLAN (Service VLAN) is being mapped to a VXLAN Network Identifier (VNI) for encapsulation and transport across the VXLAN tunnel.

Question 7

What are two characteristics of route maps in Enterprise SONIC?

ARoute-map names are not case-sensitive.

BThe permit or deny clause In route maps permits or rejects the matching routes from being redistributed.

CThey are a series of commands that contain a matching criterion and action.

DEach route map clause has the type values of Match. Set. and Act.

Answer : B, C

Route maps in Enterprise SONIC are used for controlling and modifying routing information. They contain a series of commands with matching criteria and actions. The permit or deny clause within route maps determines whether the matching routes are permitted or denied from being redistributed.
