Single choice
Refer to the exhibit.
The CE router is peering with both PE routers and advertising a public prefix to the internet. Routing to and
from this prefix will be asymmetric under certain network conditions, but packets must not be discarded.
Which configuration must an engineer apply to the two PE routers so that they validate reverse packet forwarding for packets entering their Gi2 interfaces and drop traffic from the RFC1918 space?
