Configure the Addresses to Include in Router Advertisements

To specify which addresses the router should include in its router advertisements, include the address statement at the [edit protocols router-discovery] hierarchy level:

[edit protocols router-discovery]

address address { 

    (advertise | ignore); 

    (broadcast | multicast); 

    (priority number | ineligible); 

Specify the IP address of the router, and optionally specify the following information about the router:

• Whether the server should include this address in its router advertisements—By default, the address is advertised. To disable this function, include the ignore statement at the [edit protocols router-discovery address address] hierarchy level.
• Whether the server should broadcast or multicast router advertisements—By default, advertisements are multicast if the router supports IP multicast; otherwise, they are broadcast. To modify the default functionality, include the broadcast or multicast statement at the [edit protocols router-discovery address address] hierarchy level.
• Preference of the address to become the default router—In the priority statement, a higher value for number indicates that the address has a greater preference for becoming the default router. The default value is 0, which means that the address has the least chance of becoming the default router. If the router at this address should never become the default router, include the ineligible statement. To modify the preference, include the preference statement at the [edit protocols router-discovery address address] hierarchy level. number can be a value in the range 0 through 0x80000000. The default is 0.
