Re: OSPF - Source or Destination based protocol?

So
  This thread has intrigued me a little. Protocols use source-based
routing or destination-based routing. A routing protocol is not generally
described as either, as their job is to facilitate a protocols operation.

In this case, 3IP2 is the protocol in question. And it is inherently a
destination-based protocol, because each node makes its own independent
decision about the path. IP has an option for source-based routing, but
this is turned off.

Routing protocols, like OSPF or EIGRP that are mentioned, merely exchange
information by which destination-based routing takes place independently
at different routers.

HTH,

Scott
