Correct - typing before thinking and trying to think too early in the moring
(before sleep) - sorry for the confusion.
Reference to R3, R7 should read R1, R7.
Hello All,
I am under the belief that 'good' modern BGP AS design would have all
routers in an AS fully meshed with no synchronization, particularly for a
transit AS. (Note this is not referring to BGP with MPLS cores, where only
the PE routers would run BGP).
Given the following network, I would have run bgp on R1, R3, R7, however
testing has shown that only running BGP on R1, R7 is required to achieve
full connectivity. Would anyone like to comment on the pros & cons of
running BGP on R1, R7 versus R1, R3, R7?
R1, R3, R7 share a subnet and have an IGP running on them.

Why not R1 and R7 since these are the two routers connected to the external
AS's?
