The private IP address range for the IP address group associated with the portal device is the private subnet 10.0.0.0/24 where the host resides. The public IP address range for the IP address group is the public subnet 20.20.20.0/24. Configuration procedure 1. Configure a RADIUS scheme: #...
对于高级ACL,本命令指定ACL规则中的source参数用来指定匹配该组播流策略的组播源地址范围,destination参数用来指定组播组地址范围,并且该规则中除source、destination、fragment和time-range以外的其它可选参数都将被忽略。 在引用的ACL中,若某规则指定了vpn-instance参数,则该规则将不生效。 多次执行本命令,最后一次执行的...
A group address range and a source address range are configured for the channel. Run quit Exit from the channel view. (Optional) Run unspecified-channel deny The device is configured not to forward multicast data to the groups out of the group address range.翻訳...
acl-number: specifies the number of an ACL, which is used to restrict the range of groups hosts in the VLAN can join. Both basic and advanced ACLs are supported. version version-number: specifies the version of IGMP messages to which the multicast group policy is applied. If this parameter...
• IGMP snooping in the cable modem (CM) that is used to trigger the BPI exchange for multicast.The purpose of IGMP snooping is to restrain multicast traffic and specify how a host can register a router to receive specific multicast traffic. These specifications leave a wide range of issues...

s unicast and anycast addresses. A solicited-node multicast address is formed by taking the low-order 24 bits of an address (unicast or anycast) and appending those bits to the prefix FF02:0:0:0:0:1:FF00::/104 resulting in a multicast address in the range FF02:0:0:0:0:1:FF00:...

https://www.iana.org/assignments/multicast-addresses/multicast-addresses.xhtml It is recommended to always obey the IANA ranges and not to misuse the incorrect range. If using multicast internally within your own network (not over the internet) the appropriate address range is most likely to be23...
One of the differences between unicast and multicast IP addresses is that unicast IP addresses represent a single network device while multicast IP addresses represent a group of receives. IANA has reserved the class D range to use for multicast. The first 4 bits in the first octet are 1110 ...
