Refer to the exhibit. The CE router has established a BGP peering with the PE router, and the CE will use the core infrastructure of the PE as a backbone carrier to support CSC. Which additional task can you perform to complete the configuration?
Configure static routing on the CE router.
Configure the address-family ipv4 labeled-unicast command under the neighbor configuration of the CE router for the PE.
Change the rd value to 65001:65001 under the VRF section of the PE router.
Configure OSPF on the PE router.
Refer to the exhibit. Which statement describes the result of this configuration?
R1 redistributes BGP routes into the OSPF process of VRF custabc as E1 routes.
R1 redistributes BGP routes into the OSPF process of VRF custabc as E2 routes.
R1 mutually redistributes routes between BGP 65001 and the OSPF process of VRF custabc.
R1 redistributes BGP routes into the OSPF process of VRF custabc as OIA routes.
You are writing the requirements for an MPLS L3VPN environment that uses MP-BGP between PE routers. In this environment, route targets and route distinguishers need to be advertised between the PE routers.
Which three operations meet these requirements? (Choose three.)
mandatory creation of PE-to-PE BGP sessions between the outgoing interface IP addresses
advertisement of standard communities, enabled on the PE-to-PE BGP neighbors
creation of PE-to-PE BGP sessions between loopback IP addresses
full mesh of IBGP sessions
full mesh of EBGP sessions and partial mesh of IBGP sessions
advertisement of extended communities, enabled on the PE-to-PE BGP neighbors
Which is the primary function of a MPLS L3 VPN route target?
It imports and exports identified routes into selected VRFs.
It uniquely identifies NLRIs that have the same numeric value.
It imports the external routes it identifies into VRFs that support Internet traffic
It supports QoS by classifying traffic by file type when it applies MPLS EXP bits to each packet.
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.
Which statement describes the no bgp default route-target filter command?
Prefixes that are received with route targets and distinguisher are accepted.
Prefixes that are received with route targets and distinguisher are not accepted.
Prefixes that are received with route targets that are not imported at the PE are not accepted.
Prefixes that are received with route targets that are not imported at the PE are accepted.
