Few more incorrect points in the draft:

From 3.2:

   The first version of the Border Gateway
   Protocol (BGP-1) [RFC1105]was developed as a replacement, but was
   specifically designed to work on a tree structured network (links are
   classified as upwards, downwards or sideways).

BGP-1 was *not* designed to work "on a tree structured network".
It was designed to work on a *hierarchically* structured network
as well as on a *non-hierarchically* structured network. In fact the
presence of "sideways" inter-AS link was specifically intended to
accommodate the latter.

With this mind I would suggest to replace the original text with
the following:

   The first version of the Border Gateway Protocol (BGP-1)
   [RFC1105]was developed as a replacement. It was designed to work
   on a hierarchically structured network as well as on a
   non-hierarchically structured network.

From 3.2:

   BGP version 1 [RFC1105] was the first real path-vector
   routing protocol (standardized in 1989) which was intended to relieve
   some of the scaling problems but it still assumed a tree structured
   network. 

Again, this is incorrect. BGP-1 (rfc1105) did *not* assume a tree
structured network. To the contrary, it assumes that a network
may not be a tree structured network, and that is why BGP-1
provided a mechanism to suppress routing information looping.

With this in mind I would suggest to delete" but it still assumed
a tree structured network".
