Which is a valid combination of configuration statements to set up a simple MPLS VPN on a PE?

Which command would you use to display all VRF’s including all relevant route targets and route maps associated with each VRF?

When redistributing from RIP to MG-BGP and back again it is important to consider the RIP metric as it passed through the MPLS VPN.
What is true about this function?

What is true about the following configuration?
Router bgp 1234
no bgp default ipv4 unicast
neighbor 10.3.2.1 remote-as 1234
neighbor 10.3.3.1 remote-as 1234

address-family vpnv4
neighbor 10.3.2.1 active
neighbor 10.3.3.1 active

Standard OSPF-BGP redistribution results in OSPF routes that are passing though an MPLS VPN are inserted into the receiving sites rote tables as external routes. This makes stub areas and route summarization hard to implement.
How does an MPLS VPN overcome this problem?

Which of the following is the simplest approach to take when configuring EBGP between PE and CE routers?

Which two are valid design rules for simple VPN of two PE’s each supporting two CE’s on the same VPN?
