- Overview
Conditions and Restrictions
1.
Software Version:
Ensure that the BNPs to be configured for 1:1 redundancy are running the identical BNP software
version.
2.
IP Addresses:
Because you will be setting the Virtual IP address for the GigE ports, the 10/100BaseT management
port, or the 10/100BaseT DVB-CA port (on a BNP 3xr), you must first have valid physical
IP addresses for these ports.
3.
Virtual IP address:
Both active and standby chassis must have the same virtual IP address: one VIP for the 10/100
management port and one VIP for the DVB-CA port (ETH 2 on the BNP 3xr).
An ad or video server should only send ads or video streams to the virtual IP addresses.
4.
Virtual gateway (optional):
Both active and standby chassis must have the identical virtual gateway address for the 10/100
management port. The same rule applies if configuring the virtual gateway for ETH 2.
5.
GigE ports:
Currently, the BNP does not support the Gigabit Ethernet input port level redundancy. The 1:1
chassis level redundancy will cover Gigabit Ethernet input port failure events (such as
disconnection of the Gigabit Ethernet cable, or loss of the Gigabit Ethernet link).
When a Gigabit Ethernet port delivers only one program and the program is missing for over
2 seconds, the 1:1 chassis failover is used, instead of standby program failover.
Note:
For hot-standby 1:1 chassis redundancy configured with virtual IP failover, unicast inputs cannot
be received by both the active BNP and the standby BNP simultaneously. This means that unicast
stream failover will not be immediate and the standby unit will need to initiate new unicast
sessions, which will not allow an immediate failover condition for those streams. As an
alternative, two BNP units without virtual IP coordination could be configured with identical
streams routed to both units running in parallel with the standby unit output muted.
1:1 Redundancy Best Practices and Considerations
The following information must be considered when working with 1:1 chassis-level redundancy:
•
The configuration of the standby chassis is not available from the
BNP
Element Manager
while the
unit is a standby unit.
•
Because the virtual subnet mask is not configurable, the virtual IP address must be on the same
subnet as the physical chassis IP addresses.
•
Any changes to the virtual IP address requires a reboot of the active chassis.
Redundancy Management
Use the
Global
tab screen (
) to view and configure parameters applicable to the BNP system
redundancy.
Menu Path
Access via
BNP Element Manager
Configuration tab -> Global
tab screen.
This chapter focuses primarily on use of the
Redundancy
portion (lower half) of this screen. The
