Specifying The Md Source Interface; Configuring Mdt Switchover Parameters - HP MSR2003 Configuration Manual

Step
3. Specify
address.

Specifying the MD source interface

The MTI uses the IP address of the MD source interface as the source address to encapsulate the VPN
multicast packets. The IP address of the MD source interface must be the same as the source address used
for establishing BGP peer relationship. Otherwise, correct routing information cannot be obtained.
Perform the following configuration on the PE.
To specify the MD source interface:
Step
1. Enter system view.
2. Enter MD view.
3. Specify
interface.

Configuring MDT switchover parameters

In some cases, the traffic rate of the private network multicast data might fluctuate around the MDT
switchover threshold. To avoid frequent switching of multicast traffic between the default-MDT and the
data-MDT, you can specify a data-delay period and a data-holddown period.
• MDT switchover does not take place immediately after the multicast traffic rate exceeds the
switchover threshold. It takes place after a data-delay period, during which the traffic rate must stay
higher than the switchover threshold.
Likewise, a backward switching does not take place immediately after the multicast traffic rate
•
drops below the MDT switchover threshold. It takes place after a data-holddown period, during
which the traffic rate must stay lower than the switchover threshold.
Perform the following configuration on the PE.
To configure MDT switchover parameters:
Step
1. Enter system view.
Enter MD view.
2.
3. Configure
address
switchover criteria.
4. Configure
period.
