How are route targets used to build virtual routing tables in the PE-routers?

When should you disable redistribution of IPv4 routing updates between MP-BGP neighbors?

With MPLS VPNs, which four elements will be included in an MP-BGP update exchange between
the PE
routers? (Choose two)

The VPN named my_vpn is operating on interface s0/0 a PE-router. The CE-PE routing protocol is
RIP. The MPLS backbone IGP is OSPF. However, when you review the configuration for the PErouter, you find that BGP has been configured.
What explains this configuration?

Refer to the graphic. CE-2 is using a dedicated sub-interface implementation for Internet access.
In this case, PE-2 will need to establish VPNv4 BGP neighbor relationship with which other
router(s)?

DRAG DROP
Exhibit:
CE1A and CE2A belong to the Certkiller _A VPN. Select the correct commands for the PE1 router
to establish static routing from PE1 to the CE1A 192.168.1.0/24 network by selecting them below.
Some of the commands must be entered in the correct order. Also enable propagation of the static
route intp MP-iBGP. Assume the MP-iBGP session between PE1 and PE2 have been configured
already.

routers? (Choose four.)

When redistributing routes from MP-BGP to OSPF, which three are loop prevention mechanisms?
(Choose three)

Which command configures the propagation of a static VRF route between PE-routers?
