VPRN is an IP service that connects multiple sites in a single routed domain over the provider-managed IP/MPLS network.

Each VPRN consists of a set of customer sites that must connect to the same PE router

In a VPRN service, each customer router becomes a routing peer to other customer routers

VPRN provides customer routers with transparent IP connectivity without knowledge of the MPLS core

A VRF contains a single VPRN routes.

Every VRF in a PE is associated with one or more route target attributes.

Each VPRN needs a separate VRF in each PE router.

On the 7750 SR, by default, there is a unique one-to-one association between a VPN label and a VRF

All of the above statements are true.

All of the above statements are false.

LDP must be enabled on both PE routers.

RSVP must be enabled on both PE routers.

A virtual routing/forwarding table is created per IES service.

Only one IES service can be created for a single customer ID.

More than one IP interface can be created within a single IES service.

All IP interfaces created within the same IES service belong to the same customer

Route distinguishes are contained in VPN-IPv4 prefixes.

Route distinguishes allow the same IP prefix to be used for more than one destination in a single VPRN.

Route distinguishes allow MP-BGP to manage multiple routes for the same IP prefix.

Route distinguishes are only used by the PE routes.

Routes from different customers with the same IPv4 address prefix are treated as equivalent by MP-BGP.

MP-BGP will advertise routes to other BGP sessions on the same PE without the need of policies.

The multi-protocol nature of MP-BGP allows VPRN routes to be converted into IPv4 routes in the provider core network.

MP-BGP is an enhanced version of BGP that can carry customer route prefixes for multiple VPRNs.

The outer label allows traffic to transit across the MPLS network.

The inner label identifies the VPRN service.

MP-BGP is used to signal VPRN labels.

The VPRN service label contains the customer's IP address.

SDP IDs must be locally unique.

SDPs are specific to one service type.

SDPs must use MPLS for their encapsulation.

An SDP is required for a local service.

When a PE router receives an IPv4 prefix from its local CE, it creates a VPN-IFV4 prefix.

VPN-IPv4 allows BGP to distinguish between duplicate prefixes originating from different customers.

In a VPRN, data traffic is carried in packets that have VPN-IPv4 addresses.

VPN-IFV4 addresses are only present within the service provider network.

Option A

Option B

Option C

Option D

The vc-id on the mesh-sdp must be explicitly configured.

The vc-id on the mesh-sdp is automatically assigned by a PE using the service id.

The VPLS service id, on all PE routers, does not have to match.

The VPLS service id, on all PE routers, must match.

If dynamic signaling is required, the signaling on all PE routers must be set to TLDP in the configuration of the SDPs.

The signaling on all PE routers will default to TLDP in the configuration of the SDPs; therefore, no configuration change is required for dynamic signaling.

Routes from different customers with the same IPv4 address prefix are treated as equivalents by MP-BGP.

Alcatel-Lucent 7750 SR routers support MP-BGP for VPN label signaling in a VPRN service only if LDP is used for LSP signaling.

The multi-protocol nature of MP-BGP allows VPRN routes to be distributed within the provider core network as IPv4 routes.

MP-BGP is an enhanced version of BGP that can carry a service label, a tranpot label, and customer route prefixes.

None of the above statements describe the use of an MP-BGP in a VPRN.

All of the above statements describe the use of an MP-BGP in a VPRN.

Each router requires 1 VPLS service.

Each router requires 2 VPLS services.

Each router requires 1 SDP with 2 LSPs, one to each of the other 2 routers.

Each router requires 2 SDPs.

Each router requires 3 SDPs

An OSPF adjacency can be established on an IES interface.

IES allows provider MP-BGP sessions to be extended to customers.

An IES service must use static routes in order to communicate with customer networks.

An IES interface supports OSPF and IS-IS in passive mode only.

They reduce the number of SDPs that need to be configured.

They can be used to work around physical topologies that prevent a fully meshed deployment.

They prevent loops that can be introduced by mesh deployments.

They can simplify the implementation of security policy enforcement and packet inspection.

Customers must use the same routing protocol as the service provider.

Customers belonging to the same VPRN service must use the same subnet.

Service providers only need to perform configurations on the PEs to add additional VPRNs.

For each VPRN, only one customer can be connected at each PE.

They both function as a Layer 2 switch from the service provider's perspective.

They both support SAP encapsulations of null, dot1Q and Q-in-Q.

They both use SAPs as the demarcation point between the customer and the provider.

MAC addresses are learned by VPLSes, but not by E-pipes.

The PE routers of the service are responsible for learning MAC addresses.

Flooding ensures that all PEs in a fully-meshed VPLS will learn the source address of all traffic.

MAC learning reduces flooding of frames with previously learned addresses.

Multiple VPLSes on the same PE share the same MAC FDB.

An SDP is not required for a local service.

A single SDP can carry different types of services.

An SDP can simultaneously support GRE and MPLS encapsulation.

An SDP can use the system IP address to indicate the far-end router.

The default service MTU on a VPLS service is 1514 bytes.

The default IP MTU of an IES is set based on the network port MTU.

During VC label signaling, the VC MTU is verified and must match.

All of the above.

Traffic is flooded to all SAPs in the service.

Traffic is flooded to all SAPs and spoke SDPs in the service.

Traffic is flooded to all SAPs and mesh SDPs in the service.

Traffic is flooded to all SAPs, spoke SDPs. and mesh SDPs in the service.

The traffic is not flooded.

A packet receives a service label and a transport label at the ingress PE.

A packet has its servicelabel swapped at each P router.

The egress PE pops the service label, and the transport label is forwarded.

The service label is popped by the remote CE.

Route distinguishes are used to ensure that VPRN IP prefixes are globally unique.

Route distinguishes are appended to IPv4 prefixes to form IPv6 prefixes.

Route distinguishes are used to determine which routes a VPRN should import.

CE routes use a route distinguisher to indicate which VPRN they are associated to.

VLAN tags 2 and 3 are added to the frame.

Only outer VLAN tag 2 is added.

Only inner VLAN tag 3 is added.
