What of the paths returned by shortest path do you want to send to dijkstra?
You can just get
* nodes(path) for all nodes
* nodes(path)[0] for the first, and [-1] for the last etc.
MATCH (startNode:Hosts {IP:"10.0.0.1"}), (endNode:Hosts {IP:"10.0.0.4"})
call apoc.algo.allSimplePaths(startNode, endNode, 'Link2', 6 ) YIELD path
as shortest
call apoc.algo.dijkstra(shortest[0], shortest[-1], 'Link2', 'BANDOUT')
YIELD path, weight
RETURN path, weight, shortest
