The special case of Dp-D(p+2)-brane bound state for D6-D8-brane bound states.
See this section at Hanany-Witten effect.
The fuzzy funnel/fuzzy 2-sphere noncommutative geometry of -brane intersections, from the point of the of the D6-brane non-abelian DBI-action (Gaiotto-Tomasiello 14, Fazzi 17, p. 41-46):

By the s-rule a supersymmetric configurations of D6-branes stretching between NS5-branes and D8-branes has at most one D6-brane ending on any D8-brane:

Generally Dp-D(p+2)-brane intersections geometrically engineer Yang-Mills monopoles in the worldvolume of the higher dimensional D-branes.
Specifically for , i.e. for D6-D8-brane intersections, this fits with the Witten-Sakai-Sugimoto model geometrically engineering quantum chromodynamics, and then gives a geometric engineering of the Yang-Mills monopoles in actual QCD (HLPY 08, p. 16).

Here we are showing
with
the 5d Chern-Simons theory on their worldvolume
the corresponding 4d WZW model on the boundary
both exhibiting the meson fields
(see below at WSS – Baryons)
the Yang-Mills monopole D6-branes
(see at D6-D8-brane bound state)
the NS5-branes.

D-branes and anti D-branes form bound states by tachyon condensation, thought to imply the classification of D-brane charge by K-theory
