44.5.3 IPv6 DCSCM Typical Examples

1 Source control

In order to prevent an edge switch sends multicast data at will, we configure on the edge switch that only the

switch whose port is Ethernet1/5 can send multicast data, and the group of data should be ff1e::1. The uplink

port Ethernet1/25 can forward multicast data without being restricted, so we can configure as follows.

Switch(config)#ipv6 access-list 8000 permit any-source ff1e::1

Switch(config)#ipv6 access-list 8001 permit any any

Switch(config)#ipv6 multicast source-control

Switch(config)#interface Ethernet1/5

Switch(Config-If-Ethernet1/5)#ipv6 multicast source-control access-group 8000

Switch(config)#interface Ethernet1/25

Switch(Config-If-Ethernet1/25)#ipv6 multicast source-control access-group 8001

2 Destination control

We want to confine that the users of the segment whose address is fe80::203:fff:fe01:228a/64 can not join the

ff1e::1/64 group, so we can configure as follows:

First, enable MLD Snooping in the VLAN where it locates (in this example, it is VLAN2).

Switch(config)#ipv6 mld snooping

Switch(config)#ipv6 mld snooping vlan 2

Then configure relative destination control access list and configure specified IPv6 address to use this access

list.

Switch(config)#ipv6 access-list 9000 deny any ff1e::1/64

Switch(config)#ipv6 access-list 9000 permit any any

Switch(config)#multicast destination-control

Switch(config)#ipv6 multicast destination-control fe80::203:fff:fe01:228a/64 access-group 9000

Thus, the users of this segment can only join groups other than 2ff1e::1/64.

3Multicast policy

Server 2008::1 is sending important multicast data in group ff1e::1, we can configure on its access switch as

follows:

Switch(config)#ipv6 multicast policy 2008::1/128 ff1e::1/128 cos 4

Thus this multicast flow will have a priority of 4, when it passes the TRUNK port of this switch to another

switch (generally speaking, it is a relatively high priority, the data with higher priority might be protocol data, if

a higher priority is set, when there is too much multicast data, the switch protocol might operate abnormally).
