Exam JN0-664: Question 7 - Image 1

You are running a service provider network and must transport a customer's IPv6 traffic across your IPv4-based MPLS network using BGP. You have already configured mpls ipv6-tunneling on your PE routers.

Which two statements are correct about the BGP configuration in this scenario? (Choose two.)

Answer

Suggested Answer

The suggested answer is A, C.

To transport IPv6 traffic across an IPv4-based MPLS network using BGP, you need to configure family inet6 labeled-unicast between PE routers to exchange IPv6 routes with MPLS labels. Additionally, you must configure family inet6 unicast between PE and CE routers to exchange IPv6 routes without labels. The setup ensures that IPv6 traffic can be properly transported over the MPLS network by leveraging tunneling techniques. Therefore, configuring these address families accurately enables seamless integration between different network segments.

Question 8 of 96

When using 0SPFv3 for an IPv4 environment, which statement is correct?

Answer

Suggested Answer

The suggested answer is D.

OSPFv3 supports both IPv4 and IPv6, but it requires IPv6 to be configured on the interfaces. This means that for OSPFv3 to be used in an IPv4 environment, the interfaces need to have the IPv6 address family (inet6) defined. Without this, OSPFv3 will not function correctly for IPv4.

Question 9 of 96

You are a network architect for a service provider and want to offer Layer 2 services to your customers. You want to use EVPN for Layer 2 services in your existing MPLS network.

Which two statements are correct in this scenario? (Choose two.)

Answer

Suggested Answer

The suggested answer is B, C.

EVPN (Ethernet VPN) is a technology that allows for Layer 2 services over an MPLS network by utilizing extensions to BGP. EVPN uses different types of BGP routes to distribute information about the Layer 2 network. Type 2 routes are used to advertise the MAC address and IP address pairs that are learned via ARP snooping or other mechanisms. Type 3 routes are used for creating multicast distribution trees that allow for the flooding of broadcast, unknown unicast, and multicast traffic within the EVPN instance. Segment routing and VXLAN are not mandatory for EVPN deployment in an MPLS network.

Question 10 of 96

You are configuring a Layer 3 VPN between two sites. You are configuring the vrf-target target: 65100:100 statement in your routing instance.

In this scenario, which two statements describe the vrf-target configuration? (Choose two.)

Answer

Suggested Answer

The suggested answer is A, C.

The vrf-target configuration in a Layer 3 VPN is used to manage the import and export of VPN routes. Specifically, the vrf-target target statement assigns a target community to routes. This helps in identifying BGP routes learned from remote PE devices (option A) and adds a target community to BGP routes advertised to remote PE devices (option C). This way, it ensures that routes are properly shared and understood between different parts of the VPN.
