A municipal library consortium wants a smaller OSPF LSDB and less attack surface from transit link addresses, while still advertising router loopbacks for management. Which feature matches that goal?
Select an answer to reveal the explanation.
Short Explanation
Prefix suppression is like leaving the library’s street address off the public bulletin but still listing the main phone number (the loopback). Transit link IPs stop cluttering the LSDB; management reaches the routers via loopbacks. Smaller map, fewer juicy targets.
Full Explanation
OSPF prefix suppression removes transit network prefixes from router LSAs, shrinking LSDB size and reducing the set of addresses attackers can target, while loopback and stub prefixes used for reachability can still be advertised. It is not a blanket stub that hides everything, nor a Type-5 filter. Designers use it when link addresses are unnecessary for forwarding yet loopbacks must stay visible.
