[RouterB] acl basic 2002

[RouterB-acl-ipv4-basic-2002] rule permit source 172.17.2.0 0.0.0.255

[RouterB-acl-ipv4-basic-2002] quit

# 配置名为prefix-a的地址前缀列表，允许172.17.1.0/24的路由通过。

[RouterB] ip prefix-list prefix-a index 10 permit 172.17.1.0 24

[RouterB] route-policy isis2ospf permit node 10

[RouterB-route-policy-isis2ospf-10] if-match ip address prefix-list prefix-a

[RouterB-route-policy-isis2ospf-10] apply cost 100

[RouterB-route-policy-isis2ospf-10] quit

[RouterB] route-policy isis2ospf permit node 20

[RouterB-route-policy-isis2ospf-20] if-match ip address acl 2002

[RouterB-route-policy-isis2ospf-20] apply tag 20

[RouterB-route-policy-isis2ospf-20] quit
