How this entity was disambiguated
This entity first appeared as the object of triple T1503368 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

gpt-5-mini-2025-08-07
Target entity: EIGRP Context triple: [Cisco IOS, supportsProtocol, EIGRP]
-
A.
OSPF
OSPF (Open Shortest Path First) is a widely used interior gateway routing protocol that employs link-state information to determine the most efficient path for data within an IP network.
-
B.
BGP
BGP (Border Gateway Protocol) is the primary inter-domain routing protocol used to exchange routing information and determine paths between autonomous systems on the global Internet.
-
C.
OSPFv3
OSPFv3 is the version of the Open Shortest Path First routing protocol designed to operate over IPv6 networks, providing link-state routing and support for IPv6 addressing and features.
-
D.
BGP-4+
BGP-4+ is an enhanced version of the Border Gateway Protocol designed to support routing for IPv6 networks.
-
E.
IS-IS for IPv6
IS-IS for IPv6 is an extension of the IS-IS interior gateway routing protocol that enables dynamic routing and topology discovery in IPv6 networks.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: EIGRP Description of subject: EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco-developed advanced distance-vector routing protocol used to efficiently route IP traffic within large enterprise networks.
