4A0-106 Exam Dumps - Nokia Virtual Private Routed Networks

The Nokia 7750 SR allows the setting of the maximum number of routes that can be accepted in a VRF for a VPRN service.

The "maximum-routes" command is used to specify the maximum number of remote routes that can be held within a VRF for a VPRN service.

When the "maximum-routes" command is used with the "log-only" parameter, new routes are still learned.

Once the "threshold" value is reached, no new routes are added to the VRF.

There will be increased memory usage on the PE

There will be increased CPU utilization on the PE

The CE will reject the overlapping prefix

The PE will not recognize the prefixes as being different

There is no issue with overlapping address space in a traditional Layer 3 VPN

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

The ASBRs peer with each other to transport VPN-IPv4 routes between autonomous systems.

PE routers distribute VPN-IPv4 routes to their local ASBR.

One single ASBR is required in each AS to hold the routes for all VPRNs.

RR2 advertises the VPN-IPv4 route update of 192.2.1.0/27 to RR1

RR1 advertises the VPN-IPv4 route update of 192.1.1.0/27 to RR2

RR2 advertises the VPN-IPv4 route update of 192.1.1.0/27 to PE2

PE1 advertises the VPN-IPv4 route update of 192.1.1.0/27 to RR1 and ASBRL

It is best used when a single VPN is required to provide Internet access, as well as to maintain VPN connectivity between different customer sites.

If there is no requirement for the VRF to contain the full Internet routing table, a default route to the Internet gateway router is sufficient.

Only one interface on the CE is required for both VPN and Internet connectivity.

The Nokia 7750 SR supports route leaking in full mesh and extranet VPRN topologies only.

The customer carrier does not learn any network provider routes.

The network provider must learn the customer carrier PE and CE system addresses.

Routes exchanged between CSC-CE and CSC-PE are labeled.

The customer carrier PE system addresses are populated in the CSC VRF.

BGP sessions established between RR2 and the PEs support IPv4 and VPN-IPv4 address families.

BGP sessions established between RR1 and the PEs support the IPv4 address family only.

BGP sessions established between RR1 and the PEs support IPv4 and VPN-IPv4 address families.

BGP sessions established between RR2 and the PEs support the IPv4 address family only.
