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.
From the Router Discovery tab, you can access the following pages:
• Router Discovery Configuration on page 279
Router Discovery Configuration
Use the Router Discovery Configuration page to enter or change Router Discovery
parameters.
To display the Router Discovery Configuration page, click Routing Router Discovery
Router Discovery Configuration.
To configure router discovery settings:
1. Use Interface to select the router interface for which data is to be configured.
2. Use Advertise Mode to select enable or disable. If you select enable, Router
Advertisements will be transmitted from the selected interface.
3. Use Advertise Address to enter the IP Address to be used to advertise the router.
4. Use Maximum Advertise Interval to enter the maximum time (in seconds) allowed
between router advertisements sent from the interface.
5. Use Minimum Advertise Interval to enter the minimum time (in seconds) allowed between
router advertisements sent from the interface.
6. Use Advertise Lifetime to 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.
7. Use Preference Level to specify the preference level of the router as a default router
relative to other routers on the same subnet. Higher numbered addresses are preferred. You
must enter an integer.
