refers to any legal group scope. 
 
 
Configuring IPv6 PIM common features 
For the configuration tasks in this section: 
•  In IPv6 PIM view, the configuration is effective on all interfaces. In interface view, the configuration 
is effective on only the current interface. 
•   If the same function or parameter is configured  in both IPv6 PIM view and interface view,...

 376 
•  Determine the assert timeout time (global value/interface value). 
•   Determine the join/prune interval (global value/interface level value). 
•   Determine the join/prune timeout (global value/interface value). 
•   Determine the IPv6 multicast source lifetime.  
•   Determine the maximum size of join/prune messages.  
•   Determine the maximum number of (S, G) entries in a join/prune message.  
•   Determine the DSCP value for IPv6 PIM messages.

Step Command Remarks 
3.  Configure a hello message 
filter.  pim
 ipv6  neighbor-policy 
acl6-number   No hello message filter by default 
 
 
NOTE: 
With the hello message filter configured, if hello messages of an existing IPv6 PIM neighbor fail to pass the
filter, the IPv6 PIM neighbor will be removed automatically when it times out.

IPv6 PIM common timers 
IPv6 PIM routers discover IPv6 PIM neighbors and maintain IPv6 PIM neighboring relationships with 
other routers by periodically sending hello messages.

Configuring IPv6 PIM to work with BFD 
IPv6 PIM uses hello messages to elect a DR for a multi-access network. The elected DR will be the only 
multicast forwarder on the multi-access network.  
If the DR fails, a new DR election process will start after  t h e  D R  i s  a g e d  o u t.  H oweve r,  i t  m i g h t  t a ke  a  l o n g  
period of time. To start a new DR election process i mmediately after the original DR fails, you can enable 
IPv6 PIM to work with Bidirectional Forwarding Detection...

Configuration procedure 
1. Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing:  
Enable IPv6 forwarding on each switch and config ure the IPv6 address and prefix length for each 
interface as per  Figure 103. (Details not shown.) 
Conf

igure OSPFv3 on the switches in the IP v6 PIM-DM domain to ensure network-layer 
reachability among them. (Details not shown.) 
2.  Enable IPv6 multicast routing, and enable IPv6 PIM-DM and MLD:
