R7 and R8 have sync. Enabled and I have all other routers with sync.
disabled as I generally do unless explicitly stated. However; on R7 and R8,
the BGP routes are being installed into the route table when sync. is
enabled as you will see below:
R7
router bgp 300
bgp log-neighbor-changes
neighbor 136.10.8.8 remote-as 300
neighbor 136.10.8.8 update-source Loopback0

2.0.0.0/24 is subnetted, 1 subnets
B 2.2.2.0 [20/0] via 192.168.80.100, 00:12:03
5.0.0.0/24 is subnetted, 1 subnets
B 5.5.5.0 [20/0] via 192.168.80.100, 00:12:03
So how are the 2.2.2.0 and 5.5.5.0 routes getting into the route tables if
syncronization is enabled?
