Cisco PBR Case2
如下图示:R1通过R4获取上游路由。
R2通过R5获取上游路由。
配置操作如下:
R1:
interface FastEthernet0/0
ip address 13.1.1.1 255.255.255.0
router ospf 1
network 13.1.1.0 0.0.0.255 area 0
R2:
interface FastEthernet0/1
ip address 23.1.1.2 255.255.255.0
router ospf 1
network 23.1.1.0 0.0.0.255 area 0
R3:
interface FastEthernet0/0
ip address 13.1.1.3 255.255.255.0
ip policy route-map r1
interface FastEthernet0/1
ip address 23.1.1.3 255.255.255.0
ip policy route-map r2
interface FastEthernet1/0
ip address 34.1.1.3 255.255.255.0
interface FastEthernet1/1
ip address 35.1.1.3 255.255.255.0
router ospf 1
network 13.1.1.0 0.0.0.255 area 0
network 23.1.1.0 0.0.0.255 area 0
network 34.1.1.0 0.0.0.255 area 0
network 35.1.1.0 0.0.0.255 area 0
access-list 1 permit 13.1.1.0 0.0.0.255
access-list 2 permit 23.1.1.0 0.0.0.255
route-map r1 permit 10
match ip address 1
set ip precedence priority
set ip next-hop 34.1.1.4
route-map r2 permit 10
match ip address 2
set ip precedence critical
set ip next-hop 35.1.1.5
R4:
interface FastEthernet0/0
ip address 45.1.1.4 255.255.255.0
interface FastEthernet0/1
ip address 34.1.1.4 255.255.255.0
router ospf 1
network 34.1.1.0 0.0.0.255 area 0
network 45.1.1.0 0.0.0.255 area 0
R5:
interface FastEthernet0/0
ip address 45.1.1.5 255.255.255.0
interface FastEthernet0/1
ip address 35.1.1.5 255.255.255.0
router ospf 1
network 35.1.1.0 0.0.0.255 area 0
network 45.1.1.0 0.0.0.255 area 0
