for each interface on a router
  block tcp which is both to and from that interface
I don't think that's sufficient.  What about spoofed packets arriving via
interface A, with IP source and destination both set to the address of
interface B? 
no ip source-route should fix it.

<insert replay of we don't peer with LSR inhibitors discussion>  Though temp
inhibit until YFRV deploys fixed code is understandable.
