Routes are not installed in routing table, if OSPF is configured across Logical-Systems.
I have enabled OPSF across 3 logical systems and main router. L11 <-->L12<-->Main Router<-->L13, with loopback interfaces as 192.168.100.111,192.168.100.112, 192.168.0.12, 192.168.100.113 respectively.
All of them are connected with loop cables physically.
OSPF is not functioning across the logical and main routers. I observed that main router received all Router and Network LSA’s, but it has not installed them in the main routers routing table.
Lines marked in RED are the LSA’s received from L11, L12, L13 whose loopback IPs are 192.168.100.111, 192.168.100.112, 192.168.100.113 respectively.
