![]() ![]() As the forwarding mode is MAC-based, there is a single MFIB entry created to forward these two groups. There are however a few different formats for an IPv6 address. And add ::FFFF: to the front of the string: ::FFFF:8182:640B. The following output shows a service with PIM snooping for IPv6 that has received joins for two multicast groups from different sources. Then concatenate the results with a colon between the first two and the last two octets: 8182:640B. and you can simply use a bitwise OR to set the U/L bit of the MAC address as a binary number. Both IP and MAC addresses are binary numbers. Convert the octet back into hexadecimal from binary. The problem you are having is that you are trying to do that using text. (The seventh bit will be 0, make it a 1). Note: The MAC address 11:22:33:44:55:66 will be used for the following examples. When both MLD snooping or PIM snooping for IPv6 and native IPv6 multicast are enabled on the same device, both types of forwarding entries are supported on the same forward plane, although they are used for different services. ipv6 address 2000:1::/64 eui-64 This command tells the interface to use 2000:1:: as the network portion of the IPv6 address and to automatically calculate the 64-bit host portion of the IPv6 address. Take the MAC address and convert the first octet from hexadecimal into binary. ![]() To map an IPv6 multicast address to a MAC-layer multicast address, the low-order 32 bits of the IPv6 multicast address are mapped directly to the low-order 32 bits in the MAC-layer multicast address.įor IPv6 multicast forwarding entries, IPv6 multicast snooping forwarding entries are based on MAC addresses, while native IPv6 multicast forwarding entries are based on IPv6 addresses. This section describes IPv6 multicast address to MAC address mapping and IPv6 multicast forwarding entries.įor IPv6 multicast address to MAC address mapping, Ethernet MAC addresses in the range of 33-33-00-00-00-00 to 33-33-FF-FF-FF-FF are reserved for IPv6 multicast.
