Redistribution of static routes through ospf

Aruba Employee
Q:

Redistribution of static routes through ospf



A:

Redistribution of Static Routes over OSPF is needed when one or more static routes need to be propagated over OSPF. OSPF will only redistribute classful network routes by default. Static Routes redistributed to OSPF neighbor are marked External. It does not add internal link cost to the net route cost.
