Disabling A Port From Becoming A Dynamic Router Port - HP MSR2003 Configuration Manual

You can enable MLD snooping fast-leave processing either on the current port in interface view or
•
globally for all ports in MLD-snooping view. If configurations are made in both interface view and
MLD-snooping view, the configuration made in interface view takes priority.
To enable MLD snooping fast-leave processing globally:
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Enable
fast-leave processing globally.
To enable MLD snooping fast-leave processing on a port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet interface
view.
3. Enable
fast-leave processing on the
port.

Disabling a port from becoming a dynamic router port

The following problems might exist in a multicast access network:
After receiving an MLD general query or IPv6 PIM hello message from a connected host, a router
•
port becomes a dynamic router port. Before its timer expires, this dynamic router port receives all
multicast packets within the VLAN that the port belongs to and forwards them to the host. This
affects normal multicast reception of the host.
In addition, the MLD general query and IPv6 PIM hello message that the host sends affect the
•
multicast routing protocol state on Layer 3 devices, such as the MLD querier or DR election. This
might further cause network interruption.
To solve these problems and to improve network security and the control over multicast users, you can
disable the router port from becoming a dynamic router port.
To disable a port from becoming a dynamic router port:
Step
1. Enter system view.
2. Enter
interface view.
3. Disable
becoming a dynamic router
port.
