OSPF

OSPF routing protocol configuration parameter differences between legacy and advanced routing engine.
There are parameter setting differences between legacy and advanced routing engines when configuring OSPF settings.

Route Redistribution

OSPF handles route redistribution to another routing protocol differently in each engine. When redistributing from OSPF, filters are based on a variety of criteria.
Migration Exception: The advanced routing engine does not allow redistribution of routes based on Link State Advertisement (LSA) type (external-1, external-2, inter-area, or intra-area) or origin area. You can, however use prefixes and tags associated with LSA updates.
