Hello everyone,

The networking is as follows. 

The CE12812 on the live network uses the OSPF routing protocol. Area 0 is located between the left side of CORE-III and CORE-V, and area 5 is located on the 192 network segment under CORE-V.

CORE-III needs to reject the routes to the network segment 192.128.19 and learn only the routes to 192.128.17 and 192.128.19.

How do I configure it? Please help me! Thank you!

Hi WDNJSQ,
You can configure route filtering on CORE-III. The configuration is as follows:
ip ip-prefix in index 10 permit 192.128.17.0 24
ip ip-prefix in index 20 permit 192.128.18.0 24
ospf
filter-policy ip-prefix in import
I hope it helps! Thank you!
