6. From the CLI, download the configuration script into Alteon from the TFTP server using the
following command:
To synchronize Layer 4 parameters from Alteon 1 to Alteon 2
1. On Alteon 1, synchronize the VRRP, SLB, real server, and filter settings to the other Alteon (same
ports).
Note: Alteons that are peers of one another should have an equal number of ports.
2. On Alteon 2, apply and save the configuration changes.
Tracking Virtual Routers
The tracking configuration largely depends on user preferences and network environment. The
following example is based on the configuration shown in Figure 78 - Active-Standby Configuration,
page 522 and summarized below:
• Alteon 1 is the master router upon initialization.
• If Alteon 1 is the master and it has one fewer active servers than Alteon 2, then Alteon 1
remains the master.
This behavior is preferred because running one server down is less disruptive than bringing a
new master online and severing all active connections in the process.
• If Alteon 1 is the master and it has two or more active servers fewer than Alteon 2, then Alteon
2 becomes the master.
• If Alteon 2 is the master, it remains the master even if servers are restored on Alteon 1 such
that it has one fewer or an equal number of servers.
• If Alteon 2 is the master and it has one active server fewer than Alteon 1, then Alteon 1
becomes the master.
To configure tracking virtual routers
1. Set the priority for Alteon 1 to the default value of 100.
2. Set the priority for Alteon 2 to 96.
3. On both Alteons, enable tracking based on the number of virtual routers in master mode on
Alteon and set the value to 5.
