Layer 3 VPNs

Question Image

Refer to the exhibit. A network engineer is tasked with configuring the four PE devices to enable full communication among the four connected CE devices. While beginning the configuration, the engineer encounters a connectivity issue. Which two tasks should the engineer perform to start the process correctly?

Choose two
Explanation

In an MPLS Layer 3 VPN, a PE imports a VPN route only when an export route target attached to that route matches one of the PE VRF’s import route targets. PE3 must import 100:1 and 200:2 to receive routes from the PE1/PE2 group, and PE1 must import 300:3 and 400:4 to receive routes from the PE3/PE4 group. The existing route-target pairs otherwise isolate the two groups.
