NEW QUESTION 23
Exhibit:
A Layer 3 VPN exists in the provider network and the CE devices are connecting to the PE devices using BGP. The PE devices are receiving BGP routes from the CE devices and the PE devices have the CE BGP routes in their respective routing tables. However, the remote CE devices are not receiving the BGP routes.
Referring to the exhibit, what is the problem?
- A. A route distinguisher mismatch exists.
- B. The CE devices are detecting an AS loop
- C. A VRF target community mismatch exists.
