With regard to the following extract from the minutes:

I think the following would be more accurate:

- Acee Lindem: we have now 3 methods for loop avoidance: Route Tag, DN Bit
  and for Intra-Area link (sham links)

- Eric Rosen: route tags can be eliminated in favor of the DN bit, but sham
  links cannot be.

- Acee Lindem: Thus we would have two preferred methods: DN bit and sham
  links ?

- Eric Rosen: DN bit applies only to type 3/5 LSAs.
