When configuring Internet access from a MPLS VPN using a separate subinterface, which two
configurations are required on the PE router? (Choose two.)
A.
Use the ip vrf forwarding command on the subinterface that is used for MPLS VPN access.
B.
Use the ip vrf forwarding command on the subinterface that is used for Internet access.
C.
The CE router is configured as a BGP neighbor in both the global BGP process and inside the
VPN in the VRF.
D.
ThePE-to-CE VPN and Internet routing are configured using two separate address-family ipv4
vrf
commands, one for VPN routing and one for Internet routing.
Explanation:
The internet routing is run in a (separate) MPLS VPN and therefore requires its own “ip vrf
forwarding”
command on the subinterface used for connecting the internet vrf to the customer.
The answer is not E as there is no reason for connecting the ce to the global ipv4 routing table for
this is not carrying the internet routing, a separate VRF is carrying it. The answer is not D as this is
only required if you’re using bgp as the ce-PE routing protocol. As this hasn’t been specified, it
can’t be required.
