Configuring the Router Lifetime Value
The router lifetime value specifies how long nodes on the local link should consider the adaptive security
appliance as the default router on the link. Valid values range from 0 to 9000 seconds. The default is
1800 seconds. Entering 0 indicates that the adaptive security appliance should not be considered a
default router on the selected interface.
To configure the router lifetime value in IPv6 router advertisements on an interface, perform the
following steps:
Step 1 Choose Configuration > Device Setup > Interfaces.
Step 2 Select the interface for which you want to configure the lifetime value.
The interface must have been configured with an IPv6 address. For more information see the
“Configuring IPv6 Addresses on an Interface” section on page 25-6.
Step 3 Click Edit.
The Edit Interface dialog box appears with three tabs: General, Advanced, and IPv6.
Step 4 Click the IPv6 tab.
Step 5 In the RA Lifetime field, enter a valid lifetime value.
Step 6 Click OK.
Step 7 Click Apply to save the configuration.
