display pim ipv6 rp-info [ ipv6-group-address ]

Any view

ipv6-group-address: Specifies an IPv6 multicast group by its address, in the range 
of FFxy::/16 (excluding FFx0::/16, FFx1::/16, FFx2::/16 and FF0y::), where x and y 
represent any hexadecimal number between 0 and F, inclusive. If you do not 
provide a group address, this command will display the RP information 
corresponding to all IPv6 multicast groups.

Use the display pim ipv6 rp-info command to view the RP information.

Note that:

■

The RP information includes the information of RPs dynamically found by the 
BSR mechanism and static RPs.

■

Because a non-BSR router refreshes its local RP-Set only based on the received 
BSR bootstrap messages, the system does not delete an RP even if its expiry 
time is 0. Instead, the system waits for the next bootstrap message from the 
BSR: if the bootstrap message does not contain information of the RP, the 
system will delete it.

# View the RP information corresponding to the IPv6 multicast group FF0E::101.

<Sysname> display pim ipv6 rp-info ff0e::101

PIM-SM BSR RP information:

prefix/prefix length: FF0E::101/64

RP: 2004::2

Priority: 0

HoldTime: 130

Uptime: 00:05:19

Expires: 00:02:11 

RPF prime neighbor 

RPF neighbor of the (S, G) or (*, G) entry

■

For a (*, G) entry, if this router is the RP, the RPF neighbor 
of this (*, G) entry is NULL.

■

For a (S, G) entry, if this router directly connects to the IPv6 
multicast source, the RPF neighbor of this (S, G) entry is 
NULL. 

Downstream interface(s) 
information 

Information of the downstream interface(s), including:

■

Number of downstream interfaces

■

Downstream interface name

■

Protocol type configured on the downstream interface

■

Uptime of the downstream interface(s)

■

Expiry time of the downstream interface(s)
