Yes. My fingers were thinking ISIS. > > >Page 13 presents a table of LSA's type and purpose. > >Type 2 (network) states that this LSA can be generated >by any router.

By "any router," I was referring to the "box". A box can have zero or more designated routers. I believe the statement is correct that any router -- interior, backbone, ABR, or ASBR can generate it. Incidentally, if you want to check the RFC, use RFC2328, 1247 is ancient. > >Referring to the same table : > >Type 4 (ABR) states that the contents route to 'Area >Border Router' whereas Caslow and RFC 1247 states that >they route to AS Boundary routers. You are correct. > >Phil.
