  Recently, topological interfaces between three-dimensional abelian
Chern-Simons theories were constructed. In this note we investigate such
topological interfaces in the context of the $AdS_3/CFT_2$ correspondence. We
show that it is possible to connect the topological interfaces in the bulk
Chern-Simons theory to topological interfaces in the dual CFT on the boundary.
In addition for $[U(1)]^{2N}$ Chern-Simons theory on $AdS_3$, we show that it
is possible to find boundary counter terms which lead to the $N$ conserved
currents in the dual two-dimensional CFT.
