Configuring OSPF Authentication

In order to improve the security of routing processes, OSPF au-
thentication can be configured on router.

Enabling Routes to Support Opaque
LSA
During the exchange of link state database, opaque LSAs are in-
cluded in the database summary list and transmitted to the neigh-
bor routers that also support opaque LSAs.
A router before it floods opaque LSAs to neighbor routers. It first
checks whether the neighbor routers support opaque LSAs or not.
Opaque LSAs are transmitted only to the neighbor routers that
support the function and they will be added to the link state re-
transmit list of neighbor routers. When LSU packets are multicas-
ted the neighbor routers that do not support the function receive
the LSAs passively and simply discard them.

Modifying OSPF Management
Distance
Management distance is related to the reliability of the routing in-
formation source. Management distance is an integer between 0
and 255. Higher value represents lower reliability. If the manage-
