Configuring 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 page to enter or change Router Discovery
parameters.
To display the page click Rou
ting, and then click the Router Discovery link.
To configure the router discovery settings:
1. 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 appears in the Interface field in the table heading row.
2. From the Advertise Mode
field, select Enable or Disable from the drop-down menu. If you
select Enable, Router Advertisements are transmitted from the selected interface.
3. In the Ad
vertise Address field, enter the IP Address to be used to advertise the router.
4. In the Maximu

between router advertisements sent from the interface. The allowed range for this field is 4
