Well, route-reflectors and route-reflector-clients have an iBGP
relationship with each other, yet the route-reflector-clients need not
be part of the full mesh.
iBGP speakers tell each other about locally injected routes, routes
learned from ebgp neighbors, and routes learned from ibgp
So an IBGP router within a network must be fully meshed with all other IBGP
routers in the network. If the scenarios was such that I had 5 edge routers
running both IBGP and OSPF, and 40 others routers somewhere in the middle of
these running only OSPF, that I would need all 5 IBGP routers to be
The statement in the book means that either all IBGP peers are fully
meshed ( which is a logical mesh not mandatory a physical one ), or use
Route Reflectors to reduce the number of IBGP sessions needed.
For example, if you have 10 routers that want to run IBGP over, those
10 routers doesn't
Wow...making sense now! One more question...
So an IBGP session as stated in the book, is made by use of the neighbor
command. Either, you have your directly connected neighbors defined in each
router or, you have the use of route reflectors? The only way you can
defined a neighbor that is

I guess that one must look at IBGP and EBGP as two different protocols
then...I think that is where a lot of my confusion has come in! Thanks to
everyone for the help.

Group,
In reading the BSCN book, I have stumbled across something confusing when it
is discussing route reflectors. The books states that the use of route
reflectors eliminates the need to run BGP in a full mesh environment. Based
on this statement I have assumed that BGP therefore must be
only the iBGP speakers must be in a full mesh - not necessarily the entire
network.
