Configuring IPv6 Static Neighbors
Suppressing Router Advertisement Messages
By default, router advertisement messages are automatically sent in response to router solicitation
messages. You may want to disable these messages on any interface for which you do not want the
adaptive security appliance to supply the IPv6 prefix (for example, the outside interface).
To suppress IPv6 router advertisement transmissions 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 Neighbor Discovery”
section on page 7-18.
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 Check the Suppress RA check box.
Step 6 Verify that the router advertisement message is suppressed on the interface that is configured for the IPv6
address.

Adding an IPv6 Static Neighbor
Make sure that IPv6 is enabled on at least one interface before trying to add a neighbor, or ASDM returns
an error message indicating that the configuration failed. For information about configuring IPv6 on an
interface, see the “Configuring a Static IPv6 Neighbor” section on page 25-18.
For information about configuring IPv6 Neighbor Discovery, see the “Configuring IPv6 Neighbor
Discovery” section on page 7-18.
To add an IPv6 static neighbor, perform the following steps:
Step 1 Choose Configuration > Device Management > Advanced > IPv6 Neighbor Discovery Cache.
Step 2 Click Add.
The Add IPv6 Static Neighbor dialog box appears.
Step 3 From the Interface Name drop-down list, choose an interface on which to add the neighbor.
