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
  • A Configure PE3 to export route-targets 100:1 and 200:2.
  • B Configure PE3 to import route-targets 100:1 and 200:2.
  • C Configure PE4 to import route-targets 101:1 and 202:2.
  • D Configure PE2 to export route-targets 300:3 and 400:4.
  • E Configure PE1 to import route-targets 300:3 and 400:4.
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.
