Hi,
R1 is a BGP router with synch ENABLED. It is learning three iBGP routes
which are within it's internal route table. However, only TWO of the routes
are advertised to an eBGP neighbor. Below, 10.10.0.0, 10.56.0.0 and
10.200.0.0 are to be advertised, however 10.200.0.0 is NOT advertised even
though it is in the local ip route table.
Any ideas?
