RE: Routing protocols, Internet vs Enterprises

["David Gillett" <gillettdavid () fhda edu>]

  Note that since IGRP and EIGRP are proprietary, and RIP is
limited, many enterprises use OSPF.  And I've heard that ISIS
is popular amongst ISPs, expecially in Europe.

  BGP is designed to be used to share information about points 
of contact between different network management domains; all of
the others work best within a management domain.  Whether that
domain is an enterprise or a provider is not terribly relevant.
These protocols are sharing topological information, not content.
