Chapter 44 IPv6 Multicast Protocol

44-17

Switch(config)#ipv6 pim anycast-rp self-rp-address 2004::2

Switch(config)#ipv6 pim anycast-rp 2006::1 2003::1

Please pay attention to that, for promulgating loopback interface router, if use MBGP4+ protocol, then can use

network command; or use RIPng protocol, then can use route command.

44.3.4 ANYCAST RP v6 Troubleshooting

When configuring and using ANYCAST RP v6 function, the ANYCAST RP might work abnormally because of

faults in physical connections, configurations or something others. So, the users should pay attention to the

following points:

The physical connections should be guaranteed to be correct

The PIM-SM6 protocol should be guaranteed to operate normally

The ANYCAST RP should be guaranteed to be enabled in Global configuration mode

The self-rp-address should be guaranteed to be configured correctly in Global configuration mode

The other-rp-address should be guaranteed to be configured correctly in Global configuration mode

All the interface routers should be guaranteed to be correctly added, including the loopback interface as

a RP

Use “show ipv6 pim anycast rp status” command to check whether the configuration information of

ANYCAST RP is correct

If the problems of ANYCAST still cannot be solved after checking, please use debug commands like “debug

ipv6 pim anycast-rp”, then copy the DEBUG information within three minutes and send it to the technical

service center of our company.

44.4 PIM-SSM6

44.4.1 Introduction to PIM-SSM6

Source Specific Multicast (PIM-SSM6) is a new kind of multicast service protocol. With PIM-SSM6, a multicast

session is distinguished by the multicast group address and multicast source address. In SSM6, hosts can be

added into the multicast group manually and efficiently like the traditional PIM-SM6, but leave out the shared

tree and RP management in PIM-S6M. In SSM6, SPT tree will be constructed with (S,G). G for the multicast

group address and S for the source address of the multicast which sends datagram to G. (S,G) in a pair is

named as a channel of SSM6. SSM6 serves best for the application of multicast service which is from one

station to many ones, for example, the network sports video channel, and the news channel. By default, the

multicast group address of SSM6 is limited to ff3x::/32. However this address range can be extended

according to actual situations.

PIM-SSM6 can be supported in the PIM-DM6 environment.
