Explanation:
The “Known via” text refers to the local router’s (R1’s) router bgp command, which identifies
the local router’s ASN. The rest of the output does not identify the neighboring ASN, nor the
rest of the AS_Path details. It does list that the route is external, with the text “type external”,
and the AS Hops (which is the AS_Path length).
