HP MSR2000/3000/4000 Router Series IP Multicast Command Reference

Usage guidelines
You can enable the neighbor tracking function in IPv6 PIM view or interface view. The configurations
made in IPv6 PIM view take effect on all interfaces, and the configurations made in interface view take
effect only on the current interface. If you enable the neighbor tracking function in both IPv6 PIM view
and interface view, the configuration in interface view always takes precedence.
Examples
# Enable the neighbor tracking function on Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] ipv6 pim hello-option neighbor-tracking
# On the public network, disable the neighbor tracking function on Ethernet 1/1 when the neighbor
tracking function is enabled globally.
<Sysname> system-view
[Sysname]ipv6 pim
[Sysname-pim6]hello-option neighbor-tracking
[Sysname-pim6]quit
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] ipv6 pim hello-option neighbor-tracking disable
