4. Configure filtering lists on Router B:
# Configure ACL 2002 to allow route 172.17.2.0/24 to pass.
[RouterB] acl number 2002
[RouterB-acl-basic-2002] rule permit source 172.17.2.0 0.0.0.255
[RouterB-acl-basic-2002] quit
# Configure IP prefix list prefix-a to allow route 172.17.1.0/24 to pass.
[RouterB] ip ip-prefix prefix-a index 10 permit 172.17.1.0 24
5. Configure a routing policy on Router B:
[RouterB] route-policy isis2ospf permit node 10
[RouterB-route-policy] if-match ip-prefix prefix-a
[RouterB-route-policy] apply cost 100
[RouterB-route-policy] quit
[RouterB] route-policy isis2ospf permit node 20
[RouterB-route-policy] if-match acl 2002
[RouterB-route-policy] apply tag 20
[RouterB-route-policy] quit
[RouterB] route-policy isis2ospf permit node 30
[RouterB-route-policy] quit
6. Apply the routing policy to route redistribution on Router B:
# On Router B, enable route redistribution from IS-IS and apply the routing policy.
[RouterB] ospf
[RouterB-ospf-1] import-route isis 1 route-policy isis2ospf
[RouterB-ospf-1] quit
# Display OSPF routing table information on Router A. The cost of route 172.17.1.0/24 is 100,
and the tag of route 172.17.2.0/24 is 20.
