在GNS3下配置Cisco设备的组播协议指令总结
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
