3) Verify the configuration
Use the display pim ipv6 interface command to view the IPv6 PIM configuration and running status on
each interface. For example:
# View the IPv6 PIM configuration information on Switch D.
[SwitchD] display pim ipv6 interface
Interface NbrCnt HelloInt
Vlan300 0
Vlan103 0
Vlan101 1
Vlan102 1
Use the display pim ipv6 neighbor command to view the IPv6 PIM neighboring relationships among
the switches. For example:
# View the IPv6 PIM neighboring relationships on Switch D.
[SwitchD] display pim ipv6 neighbor
Total Number of Neighbors = 3
