Area-out
The following example shows how to configure the prefix for OSPF summary LSAs. If the prefix matches
any of 111.105.3.0/24, 111.105.7.0/24, 111.105.13.0/24, it is accepted. If the prefix matches any of
111.106.3.0/24, 111.106.7.0/24, 111.106.13.0/24, it is dropped.

Area-out
The area-out attach point within OSPF allows you to filter outbound OSPF type-3 summary LSAs. The attach
point provides prefix-based matching and, hence, increased control for filtering type-3 summary LSAs.
The following example shows how to configure the prefix for OSPF summary LSAs. If the prefix matches
any of 211.105.3.0/24, 211.105.7.0/24, 211.105.13.0/24, it is announced. If the prefix matches any of
.105.3.0/24, 212.105.7.0/24, 212.105.13.0/24, it is dropped and not announced.

212.105.3.0/24,
212.105.7.0/24,
212.105.13.0/24) then
end-policy
