Static Port Configuration Example - HP A8800 Configuration Manual

Static port configuration example

Network requirements
As shown in
Router D, with Router A acting as the MLD querier.
Host A and host C are permanent receivers of IPv6 multicast group FF1E::101. GigabitEthernet 3/1/3
and GigabitEthernet 3/1/5 on Switch C are required to be configured as static member ports for
multicast group 224.1.1.1 to enhance the reliability of multicast traffic transmission.
Suppose STP runs on the network. To avoid data loops, the forwarding path from Router B to Router D is
blocked under normal conditions, and IPv6 multicast traffic flows to the receivers attached to Router D
only along the path of Router B—Router C—Router D. Configure GigabitEthernet 3/1/3 that connects
Router B to Router D as a static router port, so that IPv6 multicast traffic can flow to the receivers nearly
uninterruptedly along the path of Router B—Router D in the case that the path of Router B—Router
C—Router D gets blocked.
NOTE:
If no static router port is configured, when the path of Router B—Router C—Router D gets blocked, at least
one MLD query-response cycle must be completed before the IPv6 multicast data can flow to the receivers
along the new path of Router B—Router D, namely IPv6 multicast delivery will be interrupted during this
process.
For more information about the Spanning Tree Protocol (STP), see Layer 2—LAN Switching Configuration
Guide.

Configuration procedure
1. Enable IPv6 forwarding and assign an IP address and prefix length to each interface as per
82.
2. On Router A, enable IPv6 multicast routing, enable MLD on GigabitEthernet 3/1/1, and enable
IPv6 PIM-DM on each interface.
