Configuring Sa Message-Related Parameters; Configuration Prerequisites; Enabling Multicast Data Encapsulation In Sa Messages - HP FlexFabric 5950 series Configuration Manual

You can change the MSDP connection retry interval to adjust the interval between MSDP peering
connection attempts.
To enhance MSDP security, enable MD5 authentication for both MSDP peers to establish a TCP
connection. If the MD5 authentication fails, the TCP connection cannot be established.
IMPORTANT:
The MSDP peers involved in MD5 authentication must be configured with the same authentication
method and key. Otherwise, the authentication fails and the TCP connection cannot be established.
To control MSDP peering connections:
Step
1. Enter system view.
2. Enter MSDP view.
3. Tear down an MSDP
peering connection.
4. Set the keepalive timer
and peer hold timer for
MSDP sessions.
5. Configure the MSDP
connection retry interval.
6. Configure the device to
perform MD5
authentication when
establishing a TCP
connection with an
MSDP peer.

Configuring SA message-related parameters

This section describes how to configure SA message-related parameters.

Configuration prerequisites

Before you configure SA message delivery, complete the following tasks:
•
Configure a unicast routing protocol so that all devices in the domain can interoperate at the
network layer.
•
Configure basic MSDP features.

Enabling multicast data encapsulation in SA messages

Some multicast sources send multicast data at an interval longer than the aging time of (S, G)
entries. In this case, the source-side DR must encapsulate multicast data packet-by-packet in
register messages and send them to the source-side RP. The source-side RP transmits the (S, G)
information to the remote RP through SA messages. Then, the remote RP sends join messages to

Remarks
N/A
N/A
By default, an MSDP peering
connection is active.
By default, the keepalive
timer and peer hold timer are
60 seconds and 75 seconds,
respectively.
This command immediately
takes effect on an
established session.
The default setting is 30
seconds.
By default, the device does
not perform MD5
authentication when
establishing a TCP
connection with an MSDP
peer.
