We have three sites among one is the datacentre. these sites are running with dynamic routing protocol as OSPF. and they are configured as ospf backbone area i.e area 0.
My question is I see the routes learnt from data centre in the ospf database as LSA-5. but my datacentre and Site2 doesnt have any external routing protocol configured nor redistributed but, only static routes are redistributed in both.
Y it is showing the learnt routes are of LSA5 from Datacentre.
