I need to have both route that advertised by IOU-1 and IO-3 on IOU-2 routing table. routing protocol that used is eBGP.
here its the topology.
here its the configuration that i used:
IOU2#sh run | s bgp
router bgp 65531
bgp log-neighbor-changes
network 8.8.8.8 mask 255.255.255.255
neighbor 192.168.77.2 remote-as 65532
neighbor 192.168.78.2 remote-as 65533
maximum-paths 2
IOU1#sh run | s bgp
router bgp 65532
bgp log-neighbor-changes
network 0.0.0.0
neighbor 192.168.77.1 remote-as 65531
maximum-paths 2
IOU1#
IOU3#sh run | s bgp
router bgp 65533
bgp log-neighbor-changes
network 0.0.0.0
neighbor 192.168.78.1 remote-as 65531
maximum-paths 2
IOU3#
actually IOU-1 and IOU-3 has advertised all routes to IOU-3 and its received.
IOU3#sh ip bgp neighbors 192.168.78.1 advertised-routes

but i need to have those 0.0.0.0/0 on IOU-2 routing table. currently i have only the best one, which is form IOU-1.
IOU2#sh ip rou
