Your Path to Success: How to Pass the Nokia 4A0-106 Nokia Virtual Private Routed Networks Exam

It is the most scalable of the Inter-AS models.

VRF configuration is not required on the ASBRs.

Most routers that support VPRN functionality do not support model A by default.

It is not necessary to run MPLS at the boundary between autonomous systems.

Model B does not require the configuration of VPRN instances on the ASBRs.

The ASBRs exchange data packets that are encapsulated with a transport label and a service label.

The route target advertised in one AS is maintained and used in the remote AS.

The CLI command "configure router bgp enable-inter-as-vpn" is required on the ASBRs.

A 32 bit IPv4 address followed by a 64 bit Route Target

A 32 bit IPv4 address followed by a 64 bit Route Distinguisher

The ASBRs use MP-eBGP to peer with each other and exchange IPv4 routes between autonomous systems.

The ASBRs use MP-iBGP to peer with PE routers in their autonomous system and exchange VPN-IPv4 routes.

The ASBRs maintain a mapping of labels for IPv4 routes exchanged between autonomous systems.

The ASBRs require per-VPRN configuration.

It will label switch the packet based on this label

It will decrement the TTL and label switch the packet based on this label

It will SWAP the label for a new label and then label switch the packet

The P router does not perform any operation on this label

The As-Path is not present as it was removed with the s-override configuration command

The As-Path is not present as it was removed with the o-as-path configuration command

The As-Path is not present as a policy was configured to set it to the null value

The As-Path is not present as VPN-IPv4 routes do not propagate the IPv4 As-Path BGP attribute

PE1 pushes three labels on the IP packet: a VPN label, a BGP label, and an LDP transport label.

ASBR1 pops the LDP and BGP labels and swaps the VPN label.

ASBR2 pops the BGP label and pushes an LDP transport label.

PE2 pops two labels and forwards the unlabeled packet to its destination.

An MP-BGP update carries an MPLS label that is used as the service label for a VPRN.

There can be multiple Route Targets per route in an MP-BGP update.

There can only be one Route Distinguisher per route in an MP-BGP update.

On a specific PE, the MP-BGP updates for prefixes from a single VPRN carry different labels.

Traditional BGP attributes and MP-BGP attributes are present in an MP-BGP update.

One label per route

One label per next-hop

One label per VRF

One label per prefix

One label per tunnel
