A port authority must stop a sensitive /32 in a justice VRF from leaving via EIGRP while keeping the EIGRP adjacency up. Which approach best meets that requirement?
Select an answer to reveal the explanation.
Short Explanation
You want the handshake to stay warm but one secret address to stay home. Prefix or distribute filters trim what you advertise without killing hellos. Shutting the link or going fully passive is how you lose the neighbor along with the prefix.
Full Explanation
EIGRP filtering with distribute-lists or prefix-lists can suppress specific prefixes while leaving adjacency intact. Interface shutdown or blanket passive designs remove or prevent the neighbor relationship itself. Periodic soft clears are operational noise and do not implement durable policy. Filtering is the correct EI pattern for selective advertisement control.
