4. Configure Router C to filter out the route 3.1.3.0/24:
# Configure the IPv4 prefix list.
[RouterC] ip ip-prefix prefix1 index 1 deny 3.1.3.0 24
[RouterC] ip ip-prefix prefix1 index 2 permit 3.1.1.0 24
[RouterC] ip ip-prefix prefix1 index 3 permit 3.1.2.0 24
# Reference the prefix list to filter out the route 3.1.3.0/24.
[RouterC] ospf 1
[RouterC-ospf-1] filter-policy ip-prefix prefix1 export static
# Display the OSPF routing table of Router A.

<RouterA> system-view
[RouterA] acl number 2000
[RouterA-acl-basic-2000] rule 0 deny source 10.5.1.0 0.0.0.255
[RouterA-acl-basic-2000] rule 1 permit source any
