Routing Policies

Applying Routing Policies

To apply a routing policy, use the command appropriate to the client. Different protocols support
different ways to apply policies, but there are some generalities. Policies applied with commands that
use the keyword
table. The following are examples for the BGP and RIP protocols:
configure bgp import-policy [<policy-name> | none]
configure rip import-policy [<policy-name> | none]
Commands that use the keyword
protocol. For BGP and RIP, here are some examples:
configure bgp neighbor [<remoteaddr> | all] {address-family [ipv4-unicast | ipv4-
multicast]} route-policy [in | out] [none | <policy>]
configure bgp peer-group <peer-group-name> route-policy [in | out] [none | <policy>]
configure rip vlan [<vlan-name> | all] route-policy [in | out] [<policy-name> | none]
Other examples of commands that use route policies include:
configure ospf area <area-identifier> external-filter [<policy-map> |none]
configure ospf area <area-identifier> interarea-filter [<policy-map> | none]
configure rip vlan [<vlan-name> | all] trusted-gateway [<policy-name> | none]
To remove a routing policy, use the

Policy Examples

The following sections contain examples of policies. The examples are:
Translating an access profile to a policy on page 284
●
Translating a route map to a policy on page 286

Translating an access profile to a policy
You may be more familiar with using access profiles on other Extreme Networks switches. This example
shows the policy equivalent to an ExtremeWare access profile.
