第一題

Static Routing

int e0/0
ip add 12.1.1.1 255.255.255.0
no shut
int e0/1
ip add 45.1.1.1 255.255.255.0
no shut
int e0/2
ip add 192.168.1.1 255.255.255.0
no shut
exit
ip route 192.168.2.0 255.255.255.0 e0/0 12.1.1.2
ip route 192.168.2.0 255.255.255.0 e0/1 45.1.1.3 10

結果

  • H1-->H2

  • H2-->H1

第二題

讓 h1、h2 透過 DHCP Server取得 IP 和相關資訊，h1 可 Ping h2

int e0/0
ip addr 12.1.1.1 255.255.255.0
no shut
int e0/1
ip addr 192.168.1.1 255.255.255.0
no shut
exit
ip dhcp pool DHCP
network 192.168.1.0 /24
default-router 192.168.1.1
dns-server 8.8.8.8

結果

第三題

分別使用 RIP 和 EIGRP 讓 192.168.1.1 可 Ping 192.168.2.1

RIP

int e0/0
ip add 12.1.1.1 255.255.255.0
no shut
int lo 0
ip add 192.168.1.1 255.255.255.0
no shut
exit
router rip
ver 2
no auto-summary
network 12.1.1.0
network 23.1.1.0
network 192.168.1.0
do sh run
do ping 192.168.2.1

EIGRP

IP

int e0/0
ip addr 12.1.1.1 255.255.255.0
no shut
int lo 0
ip add 192.168.1.1 255.255.255.0
no shut
exit

router

router eigrp 1
auto-summary
network 12.1.1.0 0.0.0.255
network 192.168.1.0 0.0.0.255
do sh ip ro eigrp

結果

第四題

使用浮動路由，讓 R1 和 R2 斷線後：h1 --> R1 --> R3 --> R2 --> h2

int e0/0
ip add 12.1.1.1 255.255.255.0
no shut
int e0/1
ip add 34.1.1.1 255.255.255.0
no shut
int e0/2
ip add 192.168.1.1 255.255.255.0
no shut
exit
ip route 192.168.2.0 255.255.255.0 e0/0 12.1.1.2
ip route 192.168.2.0 255.255.255.0 e0/1 34.1.1.3 10

結果

Previous20201104 cisco EIGRP (一)Next20201118 cisco EIGRP (二)
