Hi Alvaro,

Starting to work through these and the rest of your comments.

For this one, I'll remove any implicit (e.g. "_typical_ link-state protocols" - i.e. OSPF/IS-IS) or explicit (e.g. BGP) comparisons to a _specific_ protocol, but comparing things to generic (protocol agnostic) link-state or distance vector behavior might still be necessary.

Thanks
Jordan

I want to get rid of any comparisons with "typical link-state
protocols". rift is not a typical link-state protocol, so its
specification should stand alone.


There are mentions of other protocols elsewhere, please take a look.


Thanks!


Alvaro.
