Cisco IOS Cookbook 中文精简版第二十三章 IP组播

Router-ASBR1(config)#ip multicast-routing

Router-ASBR1(config)#access-list 15 deny 239.0.0.0 0.255.255.255

Router-ASBR1(config)#access-list 15 deny 224.0.1.39

Router-ASBR1(config)#access-list 15 deny 224.0.1.40

Router-ASBR1(config)#access-list 15 permit any

Router-ASBR1(config)#interface Serial0/0

Router-ASBR1(config-if)#ip multicast boundary 15

Router-ASBR1(config-if)#ip multicast ttl-threshold 64

Router-ASBR1(config-if)#ip pim dense-mode

Router-ASBR1(config-if)#end

Router-ASBR1#

然后配置MBGP

Router-ASBR1#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router-ASBR1(config)#router bgp 65530

Router-ASBR1(config-router)#network 10.0.0.0 mask 255.0.0.0

Router-ASBR1(config-router)#neighbor 10.15.32.1 remote-as 65531

Router-ASBR1(config-router)#address-family ipv4 multicast

Router-ASBR1(config-router-af)#neighbor 10.15.32.1 activate

Router-ASBR1(config-router-af)#end

Router-ASBR1#

注释 MBGP并不像PIM一样是一种组播路由协议，只是用来传递路由信息，所以在配置中还有PIM的配置

23.17.  使用MSDP来发现外部源

提问 使用MSDP来发现另一个自治域的组播源

回答

Router-ASBR1#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router-ASBR1(config)#ip multicast-routing

Router-ASBR1(config)#interface Loopback0

Router-ASBR1(config-if)#ip address 192.168.12.1 255.255.255.255

Router-ASBR1(config-if)# ip pim sparse-mode

Router-ASBR1(config-if)#interface FastEthernet0/0

Router-ASBR1(config-if)#ip address 192.168.1.1 255.255.255.0

Router-ASBR1(config-if)#ip pim sparse-mode
