Configuring RDP

Setting the Preference Levels for Router IP Addresses

A preference level is assigned to each router IP address contained within an advertisement packet. Hosts
will select the IP address with this highest preference level to use as the default router gateway address.
By default, this value is set to zero.
To specify a preference level for IP addresses advertised from a specific RDP interface, use the
ip router-discovery interface preference-level
value to 10 for the IP address associated with the Marketing IP router interface:
-> ip router-discovery interface Marketing preference-level 10
Note that router IP address preference levels are only compared with the preference levels of other routers
that exist on the same subnet. Set preference levels low to discourage selection of a specific router.
