Important Considerations
■
This display contains the summary information plus three additional
fields: interface, metric, and ASEType.
■
Your system has one unified IP routing table. Routing policies allow
you to control the flow of information among the network, the
protocols, and the routing tables on your system.
■
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 system tracks 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.
Fields in the IP OSPF Policy Detail Display
Field Description
Action Action for the route (
accept
or
reject
)
ASEType Type of external metric —
Type 1
or
Type 2
— specified in
the AS external link advertisement. OSPF boundary routers use
Type 1 as default. Only applicable to export policies.
Index Index number of the policy
Interface Origin interface (only applicable when specifying
direct
as
Origin Protocol)
Metric Adjustment to the cost metric of routes that match the policy
Protocol Origin protocol (for export policies only). Can also specify a
direct
or
static
route.
