5. Set the filtering list.
# Set ACL 2002 to match 172.17.2.0/24.
[SwitchB] acl number 2002
[SwitchB-acl-basic-2002] rule permit source 172.17.2.0 0.0.0.255
[SwitchB-acl-basic-2002] quit
# Set an IP prefix list named prefix-a to match 172.17.1.0/24.
[SwitchB] ip ip-prefix prefix-a index 10 permit 172.17.1.0 24
6. Set a Route-Policy.
[SwitchB] route-policy isis2ospf permit node 10
[SwitchB-route-policy] if-match ip-prefix prefix-a
[SwitchB-route-policy] apply cost 100
[SwitchB-route-policy] quit
[SwitchB] route-policy isis2ospf permit node 20
[SwitchB-route-policy] if-match acl 2002
[SwitchB-route-policy] apply tag 20
[SwitchB-route-policy] quit
7. Apply the Route-Policy when routes are imported.
# Configure Switch-B and apply the Route-Policy when routes are imported.
[SwitchB] ospf
[SwitchB-ospf-1] import-route isis 1 route-policy isis2ospf
[SwitchB-ospf-1] quit
# Check the OSPF routing table of SwitchA. You can view the cost of the route with the
destination address as 172.17.1.0/24 is 100, and the tag of the route with the destination
address as 172.17.2.0/24 is 20. Other routing attributes do not change.
