用GNS3配置cisco设备组播协议方法如下:

 

配置结果:

配置文件一段如下:

interface Ethernet0/3.100
 encapsulation dot1Q 100
 ip address 168.1.1.1 255.255.255.0
 ip pim sparse-mode
 ip igmp static-group 237.200.10.1
 ip igmp static-group 237.200.11.1
 vrrp 1 ip 168.1.1.2
 vrrp 1 priority 140
!
interface Ethernet0/3.200
 encapsulation dot1Q 200
 ip address 168.1.2.1 255.255.255.0
 ip pim sparse-mode
 ip igmp static-group 237.200.10.1
 ip igmp static-group 237.200.11.1
 vrrp 2 ip 168.1.2.2
 vrrp 2 priority 160
!

 

 

配置方法:

在边缘路由器上做如下配置:

Router(config-if)#int vlan 200
Router(config-if)#ip add 168.1.2.1 255.255.255.0
Router(config-if)#no sh
Router(config-if)#vrrp 1 ip 168.1.2.1
Router(config-if)#vrrp 1 priority 140

ip pim sparse-mode

绑定是:(config-if)#vlan-id dot1q 200

interface Ethernet0/0
 ip address 10.110.5.2 255.255.255.0
 ip pim sparse-mode
 half-duplex
 vlan-id dot1q 100
  exit-vlan-config
 !


SwitchC(config)#ip igmp snooping vlan 100 mrouter interface fa0/0
SwitchC(config)#ip igmp snooping vlan 200 mrouter interface fa0/0
SwitchC(config)#end
SwitchC#sh ip igmp snooping mrouter
Vlan    ports
----    -----
 100    Fa0/0(static)
 200    Fa0/0(static)

SwitchC(config)#ip igmp ?
  immediate-leave  Leave groups immediately without sending last member query,
                   use for one host network only
  limit            IGMP limit
  snooping         Global IGMP Snooping enable for Catalyst VLANs
  ssm-map          SSM mapping commands
  vrf              Select VPN Routing/Forwarding instance

 

全局使能igmp snooping(默认状态下是使能的)
SwitchC(config)#ip igmp snooping

 

二层组播静态加入
SwitchC(config)#int vlan 100
SwitchC(config-if)#ip igmp join-group 224.1.1.4

SwitchC(config)#int fa0/0
SwitchC(config-if)#switchport trunk allowed vlan remove  1,1001-1005

相应配置文件会有 interface FastEthernet0/0
 switchport trunk allowed vlan 1,100,200,1001-1005
 switchport mode trunk


如果console不断提示;
*Mar  1 00:05:25.691: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet1/1 (not full duplex), with SwitchA FastEthernet0/0 (full duplex).

 

则在路由器一端端口配置一条 :

Router(config-if)#duplex full
 

完整边界路由子接口配置命令列表:(igmp 默认已配置好,为version2,如果没有显示更改版本不显示,否则显示相应版本号)

Router#conf t

Router(config)#int eth1/0.200

Router(config-subif)#encapsulation  dot1q 200

Router(config-subif)#vrrp 1 ip 168.1.2.13

Router(config-subif)#vrrp 1 priority 150

Router(config-subif)#ip pim sparse-mode

 


证明igmp-snooping不能配置证据:

SwitchD(config)#int vlan 100
SwitchD(config-if)#ip igmp ?
  access-group                IGMP group access group
  explicit-tracking           Enable/Disable IGMP explicit-tracking
  helper-address              IGMP helper address
  immediate-leave             Leave groups immediately without sending last
                              member query, use for one host network only
  join-group                  IGMP join multicast group
  last-member-query-count     IGMP last member query count
  last-member-query-interval  IGMP last member query interval
  limit                       IGMP limit
  mroute-proxy                Mroute to IGMP proxy
  proxy-service               Enable IGMP mroute proxy service
  querier-timeout             IGMP previous querier timeout
  query-interval              IGMP host query interval
  query-max-response-time     IGMP max query response value
  static-group                IGMP static multicast group
  unidirectional-link         IGMP unidirectional link multicast routing
  v3lite                      Enable/disable IGMPv3 Lite
  version                     IGMP version

发现:
SwitchD(config)#ip igmp snooping vlan 100 mrouter interface fa0/0
fa0/0是多播的来源端口,配置了其他端口才不会接受不相关的组播 fa0/0为路由连接口

ip igmp snooping vlan 100 配置文件没更改
