Important Considerations
■
Your module uses one unified IP routing table. Routing policies allow
you to control the flow of information among the network, the
protocols, and the routing table on your module.
■
There are two classes of routing policies:
■
Import policies
— Control which OSPF non-self-originated
external routes are stored in the routing table. OSPF import policies
control only what the local router uses. They do not affect the
propagation of non-self-originated external routes to other routers.
■
Export policies
— Used on OSPF boundary routers to control
which self-originated external routing updates are placed in the
link-state database for propagation over the network. In this way,
export policies govern what other routers learn with regard to the
local boundary router’s self-originated information.
■
The module tracks the policies that you define in both OSPF and
Routing Information Protocol (RIP), so the indexes that are assigned to
your policies may have gaps. For example, if you have OSPF policies 1
and 2, and RIP policies 3 through 6, the next policy is 7.
