华为ospf与rip相互引入引起的问题.docx

将ospf与rip相互引入。由于华为的ospf内部路由优先级为10，外部引入路由优先级为150 。RIP的优先级为100。所以RIP的路由优先级比ospf的外部引入的小，故RIP路由优先于ospf外部路由。刚构建的拓扑，并不存在环路和次优路径，当ar2上的接口出现down的现象后，才会出现次优路径或者环路现象ar4dispip routing-table Route Flags: R - relay, D - download to fibRouting Tables: PublicDestinations : 18 Routes : 18 Destination/Mask Proto Pre Cost Flags NextHop Interface /24 OSPF 10 2 D GigabitEthernet0/0/0 /24 OSPF 10 2 D GigabitEthernet0/0/0 /24 Direct 0 0 D GigabitEthernet0/0/0 /32 Direct 0 0 D GigabitEthernet0/0/0 55/32 Direct 0 0 D GigabitEthernet0/0/0 /32 OSPF 10 1 D GigabitEthernet0/0/0 /32 OSPF 10 2 D GigabitEthernet0/0/0 /32 Direct 0 0 D LoopBack0 /8 Direct 0 0 D InLoopBack0 /32 Direct 0 0 D InLoopBack055/32 Direct 0 0 D InLoopBack0 /24 O_ASE 150 1 D GigabitEthernet0/0/0 /24 O_ASE 150 1 D GigabitEthernet0/0/0 /24 O_ASE 150 1 D GigabitEthernet0/0/0 /24 Direct 0 0 D GigabitEthernet0/0/1 /32 Direct 0 0 D GigabitEthernet0/0/1 55/32 Direct 0 0 D GigabitEthernet0/0/155/32 Direct 0 0 D InLoopBack0ar4[ar3]dispip routing-table Route Flags: R - relay, D - download to fibRouting Tables: PublicDestinations : 18 Routes : 18 Destination/Mask Proto Pre Cost Flags NextHop Interface /24 OSPF 10 2 D GigabitEthernet0/0/0 /24 Direct 0 0 D GigabitEthernet0/0/0 /32 Direct 0 0 D GigabitEthernet0/0/0 55/32 Direct 0 0 D GigabitEthernet0/0/0 /24 OSPF 10 2
