實驗：配置路由政策
環境：EVE
涉及協定： RIP OSPF EIGRP BGP
首先看下實驗需要的拓撲以及IP位址協定
這個顔色很漂亮吧
首先檢視接口是否UP IP位址的配置 以及協定是否起來了

都沒啥問題 接下來看題：
（1）檢視R1目前各協定的鄰居狀态：
R1#show ip ospf neighbor
14.1.1.4 1 FULL/DR 00:00:33 14.1.1.4 Ethernet0/3
R1#show ip eig
R1#show ip eigrp neig
R1#show ip eigrp neighbors

R1#show run | s rip
R1#show ip b
R1#show ip bgp neig
R1#show ip bgp neighbors
BGP neighbor is 15.1.1.5, remote AS 1, external link
BGP version 4, remote router ID 15.1.1.5
BGP state = Established, up for 00:17:10
Last read 00:00:33, last write 00:00:12, hold time is 180, keepalive interval is 60 seconds
R1#show ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 12.1.1.0/24 is directly connected, Ethernet0/0
L 12.1.1.1/32 is directly connected, Ethernet0/0
13.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 13.1.1.0/24 is directly connected, Ethernet0/1
L 13.1.1.1/32 is directly connected, Ethernet0/1
14.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 14.1.1.0/24 is directly connected, Ethernet0/3
L 14.1.1.1/32 is directly connected, Ethernet0/3
15.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 15.1.1.0/24 is directly connected, Ethernet0/2
L 15.1.1.1/32 is directly connected, Ethernet0/2
（3）在R1上将EIGRP學習到的路由重分布進RIP：
R1(config)#router rip
R1(config-router)#redi
R1(config-router)#redistribute eig
R1(config-router)#redistribute eigrp
% Incomplete command.
R1(config-router)#redistribute eigrp ?
<1-65535> AS number
R1(config-router)#redistribute eigrp 1
R1(config-router)#do wr
4）檢視RIP路由器R3的路由表：
R3#show ip route
C 13.1.1.0/24 is directly connected, Ethernet0/0
L 13.1.1.3/32 is directly connected, Ethernet0/0
（5）修改RIP重分布時的預設Metric值：
R1(config-router)#
*Apr 11 07:57:15.072: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet0/2 (not full duplex), with R5 Ethernet0/0 (full duplex).
R1(config-router)#default-metric 10
（6）再次檢視RIP路由器R3的路由表：
Gateway of last resort is not set
R 12.0.0.0/8 [120/10] via 13.1.1.1, 00:00:26, Ethernet0/0
（7）手工指定EIGRP重分布進RIP時的Metric值：
R1(config-router)#redistribute eigrp 1 metric 15
（8）再次檢視RIP路由器R3的路由表：
Gateway of last resort is not set
R 12.0.0.0/8 [120/15] via 13.1.1.1, 00:00:22, Ethernet0/0
（10）檢視OSPF路由器R4的路由表：
R4#show ip route
C 14.1.1.0/24 is directly connected, Ethernet0/0
L 14.1.1.4/32 is directly connected, Ethernet0/0
（16）檢視EIGRP路由器R2的路由表：
R2#sh ip route
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 10.1.1.0/24 is directly connected, Ethernet0/1
L 10.1.1.1/32 is directly connected, Ethernet0/1
L 12.1.1.2/32 is directly connected, Ethernet0/0
（17）修改重分布進EIGRP時的預設Metric值：
R1(config)#router eigrp 1
R1(config-router)#default-metric 10000 100 255 1 1500
将其他協定重分布進eigrp的時候必須帶上metric參數，這五個參數分别是指bangwidth、delay、reliability、loading、MTU
（18）再次檢視EIGRP路由器R2的路由表：
R2#show ip route
14.0.0.0/24 is subnetted, 1 subnets
D EX 14.1.1.0 [170/307200] via 12.1.1.1, 00:00:24, Ethernet0/0
（19）重分布直連路由進EIGRP時使用Route-MAP：
R1(config)#route-map NET15 permit 10
R1(config-route-map)#match interface ethernet 0/2
R1(config-router)#redistribute connected route-map NET15
（20）檢視EIGRP路由器R2的路由表：
R2#sh ip route
15.0.0.0/24 is subnetted, 1 subnets
D EX 15.1.1.0 [170/307200] via 12.1.1.1, 00:00:15, Ethernet0/0
隻有與Route-Map中定義的接口相比對的serial 1/0被重分布進了EIGRP
