Configure Router Discovery
The Router Discovery protocol is used by hosts to identify operational routers on the subnet.
Router Discovery messages are of two types: Router Advertisements and Router
Solicitations. The protocol mandates that every router periodically advertise the IP Addresses
it is associated with. Hosts listen for these advertisements and discover the IP Addresses of
neighboring routers.

Router Discovery Configuration

Use the Router Discovery Configuration screen to enter or change Router Discovery
parameters.
To configure the router discovery parameters:
1. Select Routing > Router Discovery.
2. Select the router interface for which data is to be configured.
To perform the same configuration on all interfaces, select the check box in the heading
row. To configure a single interface, select the check box associated with the interface.
The interface number displays in the Interface field in the table heading row.
3. Select Enable or Disable from the drop-down menu.
If you select Enable, Router Advertisements are transmitted from the selected interface.
4. Enter the IP Address to be used to advertise the router.
5. Enter the maximum time (in seconds) allowed between router advertisements sent from the
interface.
The value must be in the range of (4 to 1800). Default value is 600.
6. Enter the minimum time (in seconds) allowed between router advertisements sent from the
interface.
The value must be in the range of (3 to 1800). Default value is 450.
7. Enter the value (in seconds) to be used as the lifetime field in router advertisements sent
from the interface.
This is the maximum length of time that the advertised addresses are to be considered as
valid router addresses by hosts. The value must be in the range of (4 to 9000). Default
value is 1800.
