The Implementing Cisco Service Provider VPN Services certification exam tests candidates’ knowledge of various VPN technologies, including IPsec, MPLS Layer 3 VPNs, MPLS Layer 2 VPNs, and VPN high availability. It also covers topics such as VPN routing and forwarding, VPN security, and VPN monitoring and troubleshooting. Successful candidates will demonstrate their ability to configure VPN services, troubleshoot VPN issues, and provide VPN solutions in a service provider environment.

NO.25 In MPLS Layer 3 VPN implementations, what is used on the PE router to isolate potential overlapping routing information between different customers?

route targets

VRFs

VC IDs

pseudowire IDs

pseudowire classes

NO.26 Which two statements describe primary differences between MPLS Layer 2 and Layer 3 VPNs?
(Choose two.)

Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use L2TPv3 tunneling.

Layer 2 VPNs use AToM, but Layer 3 VPNs use MPLS/BGP.

Layer 2 VPNs use BGP, but Layer 3 VPNs use VPLS.

Layer 2 VPNs use L2TPv3 tunneling, but Layer 3 VPNs use GRE tunneling.

Layer 2 VPNs use IPsec tunneling, but Layer 3 VPNs use pseudowires to provide tunneling.

NO.27 Drag and drop the EVPN components from the left onto the correct planes on the right.

NO.28 An engineer noticed that PE3 is failing to accept IPv6 traffic information from PE1.
The engineer confirmed that both PE3 and PE1 routers are configured accurately with IPv6 protocol.
To eliminate IPv6 traffic loss issue, which action must the engineer take to solve the problem?

Disable 6PVE that provides local IPv6 reachability over MPLS.

Configure 6PE that provides global IPv6 reachability over IPv4 MPLS

Allow PE routers use the MP-iBGP extensions in the IPv6 network configuration to exchange IPv6 reachability information.

Configure 6PE forwarding between 6PE routers based on the IPv6 header

NO.29 Refer to the exhibit. A customer with multiple sites requested additional monitoring for Ethernet connections to its service provider. The service provider implemented Ethernet OAM on the PE side of the PE-CE links between the PE and CE routers. Which command must be implemented on both CEs to support Ethernet OAM and allow the PE to initiate the connection?

ethernet oam mode passive

ethernet oam max-rate 8

ethernet uni id 2004-20

ethernet cfm mip level 7

On the CE interfaces you must enable Ethernet OAM in passive mode so they will respond to OAM frames (such as continuity checks and link-monitor messages) initiated by the PE.

NO.30

An engineer is trying to configure an EVPN VWPS. What is the issue with this configuration?

The member in the VPWS context should be the PE-facing interface.

The 12vpn evpn command should be instance 101.

Interface GigabitEthernet0/1/0 should not have any IP address.

The service instance and the EVPN instance are different.

NO.31 Refer to the exhibit. A network engineer with an employee ID: 5100:21:535 must configure routers PEA and PEB so that traffic between CE1 and CE2 is multihomed and load-balanced.
The two 10GE links in Ethernet bundle 10 are sending traffic at different rates. Which action must the engineer take on PEX and PEY to complete the configuration?

Set the identifier type 11.12.11.12.11.12.11.12.11 on the PEX and PEY routers.

Change the source and destination AC values to 5 and 6 respectively.

Set the identifier type 33.34.33.34.33.34.33.34.33 on the PEX and PEY routers.

Set the neighbor evpn vpi value to 200 on the PEX and PEY routers.

For EVPN multihoming with Ethernet Bundles, all PEs attached to the same multihomed CE must share the same Ethernet Segment Identifier (ESI). In this case, PEA is already configured with identifier type 0 11.12.11.12.11.12.11.12.11. To achieve load balancing and redundancy, PEX and PEY must be configured with the same ESI value. This ensures that the Ethernet Segment is recognized as a single multihomed link and enables all-active forwarding.

NO.32 Refer to the exhibit. PE1 and PE2 are exchanging VPNv4 routes for CE1 and CE2, and PE3 contains the default route to the internet. If the three devices are operating normally, which two conclusions describe this configuration? (Choose two.)

The CE1 and CE2 VRFs can exchange routes only between their respective VRFs on PE1 and PE2.

All three routers must be running a distance-vector routing protocol.

All three routers must be running MP-BGP.

The CE1 and CE2 VRFs can access the default route provided by the Internet VRF.

Only the CE2 VRF can access the default route provided by the Internet VRF.

Let me trace the route-target (RT) import/export relationships, since that’s what determines route leaking between VRFs:

A route tagged with an export RT is installed by any VRF importing that same RT.
CE1 exports 100:1 → imported by CE2 and Internet
CE2 exports 200:2 → imported by CE1 and Internet
Internet exports 300:3 → imported by CE2 only (CE1 does not import
300:3)
Exchanging VPNv4 prefixes between PE routers across the MPLS backbone requires MP-BGP (the VPNv4 address family carries the RD, route targets, and VPN labels). Without MP-BGP running on all three PEs, none of this RT-based route leaking happens. This is a baseline requirement of MPLS L3VPN.
The default route lives in the Internet VRF, which exports 300:3. Only CE2 imports 300:3, so only the CE2 VRF installs and can use that default route. CE1 imports just 200:2 – it never imports
300:3, so it cannot reach the Internet VRF’s default route. Hence only CE2 has Internet access.

NO.33 Which tool identifies the point of failure in a P2MP LSP from the ingress LSR?

Jitter TLV

SPAN

P2MP traceroute

P2MP ping

NO.34 Refer to the exhibit.

An engineer has configured router 1 to provide shared services to clients behind router 2. To complete the implementation so that routes from router 1 are accepted, what must the engineer configure on router 2?

with import route targets 101:102 and 202:201

with import route targets 201:202 and 401:402

with export route targets 301:202 and 101:102

with export route targets 201:202 and 401:402

NO.35 Refer to the exhibit.

Which statement about this configuration is true?

Router 1 will accept multicast routes with a route-target of 12:1.

192.168.1.2 must be reachable by all routers participating in the mvpn-intranet MVRF.

Router 1 has statically defined thresholds for data MDT.

The MVRF must be configured on each router on the customer and service provider networks.

NO.36 Which mechanism reduces the network flooding caused by host ARP learning behavior?

ARP suppression

storm control

root guard

BPDU guard

NO.37 Which two statements about MPLS L3 VPN RDs are true? (Choose two.)

They enable EIGRP to use address families to separate traffic between IPv4 and VPNv4.

They are represented as 32-bit values

They are represented as 64-bit values.

They enable OSPF to import and export routes into the global routing table of a router.

They allow BGP to uniquely identify duplicate routes.

NO.38 Refer to the exhibit. PE1 is located at a company’s headquarters, with PE2 and PE3 at remote offices. A service provider implemented E-Tree for the company, with PE1 serving at the root and PE2 and PE3 serving as leaf nodes in the topology. For redundancy, PE3 offers some of the same services that that offered at headquarters. However, when the link to PE1 fails, users on PE2 cannot access the services on PE3. Which action must the engineer take to resolve the issue?

Set the same MAC address for MLACP on each device.

Change the L2transport encapsulation type to MPLS.

Add a secondary IP address to the interface facing the EVPN.

Reconfigure PE3 as a root node.

In an EVPN E-Tree, leaf nodes cannot communicate with other leaves-only with roots. With PE1 (root) down, PE2 (leaf) cannot reach services on PE3 (also leaf). Making PE3 a root node permits leaf-to-root forwarding and restores access when the PE1 link fails.

NO.39 Refer to the exhibit. OSPF routers R1 and R2 are connected via a 1G Ethernet link. R1 has IP address 10.1.1.1/24 on its Gi0/0/1 interface, and R2 has IP address 10.1.1.2/24 on its Gi0/0/1 interface OSPF with process ID 1 is configured on both routers, and both routers are in the same OSPF area. However, R1 cannot establish an OSPF adjacency with R2. The network engineer who is troubleshooting the problem found these log messages on R1. Which action must the engineer take to resolve the issue?

Configure ip ospf network non-broadcast under Gi0/0/1 on R2

Configure router ospf 1 under the global configuration on R2

Configure no passive-interface under Gi0/0/1 on R1

Configure prefix-suppression under the global configuration on R1

The debug on R1 reports “incorrect ospf process id in packet received,” meaning R2 is sending hellos from a different (or absent) OSPF instance. Enabling router ospf 1 globally on R2 starts the same process-ID that R1 is running, so the packets are accepted and the adjacency forms.

NO.40 Refer to the exhibit.

If the two devices are operating normally, which two conclusions can you draw from this configuration? (Choose two.)

CE1 must use OSPF to establish a neighbor relationship with PE1.

PE1 labels the routes it learns from CE1 with the route-target 222:2 and shares them with its VPNv4 peers.

PE1 labels the routes it learns from CE1 with the route-target 111:1 and shares them with its VPNv4 peers.

The PE-CE routes between the devices are being exchanged by OSPF

CE1 is supporting CSC.
