基于华为的isis路由泄露

1.看拓扑配置接口ip地址 及环回口

AR1
isis 15
network-entity 49.0124.0000.0000.0001.00
log-peer-change topology 
cost-style wide 
is-level  level-1-2
int g0/0/1 
isis enable 15
isis circuit-level level-2
int loo 0 
isis enable 15
// is-name map 0000.0000.0001 R1
int g0/0/0
isis enable 15 
isis circuit-level level-1

R2,R4纯level 1 R3纯level 2

3.路由泄露

R1:
ip ip-prefix R3 index 10 permit 3.3.3.0 24
isis 15 
import-route isis  level-2 into level-1 filter-policy ip-prefix R3
