网络拓扑注解:
R1运行两种路由协议ospf和rip,需要配置路由重分发,配置vpn,对端路由为R2,配置PAT
R2运行ospf路由协议,配置vpn,对端路由为R1
3L-1运行rip路由协议,f0/1 - 4 trunk 运行vtp(server),pvst(vlan1根)vlan1 走f0/1 - f0/1
3L-2运行rip路由协议,f0/1 - 4 trunk 运行vtp(client),pvst(vlan2根)vlan2走f0/2 - f0/2
SW1 f0/0 - 1 trunk 运行vtp(client),f0/10 - 15 属于vlan1
SW1 f0/0 - 1 trunk 运行vtp(client),f0/10 - 15 属于vlan2
3-L1和3L-2的f0/5 配置HSRP, 虚拟ip为 192.168.1.254
PC1属于vlan2 ip:10.10.2.2 24
PC2属于vlan1 ip:10.10.1.2 24
pc3不属于任何valn ,网关地址为HSRP的虚拟ip地址:192.168.1.254

3L-2(config-if)#no shut
3L-2(config-if)#standby 10 ip 192.168.10.254
3L-2(config-if)#no ip redirects
3L-2(config-if)#standby 10 priority 150
3L-2(config-if)#exit
PVST的配置
3L-1(config)#spanning-tree vlan 1 root primary
3L-1(config)#int f0/2
3L-1(config-if)#spanning-tree vlan 2 cost 18
3L-1(config-if)#exit
3L-1(config)#exit
3L-2(config)#spanning-tree vlan 2 priority 4096
VTP的配置:
3L-1#vlan database
3L-1(vlan)#vtp domain 51cto
3L-1(vlan)#vtp server
3L-1(vlan)#vtp pruning
3L-2#vlan database
3L-2(vlan)#vtp domain 51cto
3L-2(vlan)#vtp client
3L-2(vlan)#vtp pruning
3L-2(vlan)#exit
三层交换机的配置(以3L-1为例):
3L-1(config)#int vlan 1
3L-1(config-if)#ip add 10.10.1.1 255.255.255.0
3L-1(config-if)#no shut
3L-1(config-if)#exit
3L-1(config)#int vlan 2
3L-1(config-if)#ip add 10.10.2.2 255.255.255.0
3L-1(config-if)#no shut
3L-1(config-if)#exit
3L-1(config)#router rip
3L-1(config-router)#version 2
3L-1(config-router)#network 192.168.100.0
3L-1(config-router)#network 172.16.1.0
3L-1(config-router)#network 192.168.10.0
3L-1(config-router)#network 10.10.1.0
3L-1(config-router)#network 10.10.2.0
3L-1(config-router)#no auto-summary
3L-1(config-router)#exit
3L-1(config)#exit
VPN的配置
配置IKE协商
A(config)#crypto isakmp enable
A(config)#crypto isakmp policy 1
A(config-isakmp)#hash md5
A(config-isakmp)#encryption des
A(config-isakmp)#authentication pre-share
A(config-isakmp)#exit
A(config)#crypto isakmp key wocao address 172.16.3.2
配置IPSec相关参数
A(config)#access-list 101 permit ip any any
A(config)#crypto ipsec transform-set wocao ah-md5-hmac esp-des
配置到端口应用
A(config)#crypto map wocaomap 1 ipsec-isakmp
A(config-crypto-map)#set peer 172.16.3.2
A(config-crypto-map)#set transform-set wocao
A(config-crypto-map)#match address 101
A(config-crypto-map)#exit
A(config)#int e0/3
A(config-if)#crypto map wocaomap
实验结果:
1.配置路由重分发,R2和两台三层都学到了对方的路由,但是当配置PAT后R1上的路由重分发失效,问:是不是与PAT中的访问控制列表有关系
2.配置的vpn有问题,*Mar 1 01:58:27.959: %CRYPTO-4-RECVD_PKT_NOT_IPSEC: Rec'd packet not an IPSEC packet.
(ip) vrf/dest_addr= /224.0.0.5, src_addr= 172.16.3.2, prot= 89
*Mar 1 01:59:27.975: %CRYPTO-4-RECVD_PKT_NOT_IPSEC: Rec'd packet not an IPSEC packet.
是否与101访问控制列表有关系
别的没有什么问题了
