Section 11.1 says:

   Redirect attacks can also be achieved by any host in order to flood a
   victim or steal its traffic.  A host can send a Neighbor
   Advertisement (in response to a solicitation) that contains its IP
   address and a victim's link-layer address in order to flood the
   victim with unwanted traffic.  Alternatively, the host can send a
   Neighbor Advertisement that includes a victim's IP address and its
   own link-layer address to overwrite an existing entry in the sender's
   destination cache, thereby forcing the sender to forward all of the
   victim's traffic to itself.

It should say:

   victim or steal its traffic.  A host can send a Neighbor
   Advertisement (in response to a solicitation) that contains its IP

   victim with unwanted traffic.  Alternatively, the host can send a
   Neighbor Advertisement that includes a victim's IP address and its
   own link-layer address to overwrite an existing entry in the sender's
   neighbor cache, thereby forcing the sender to forward all of the
   victim's traffic to itself.

Notes:

s/destination cache/neighbor cache/

Neighbor advertisement affects neighbor cache and not destination cache.
