Routing Policies
ExtremeWare XOS 11.3 Concepts Guide

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
import-policy
control the routes imported to the protocol from the switch routing
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
route-policy
control the routes advertised or received by the
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
none
option in the command.
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.
ExtremeWare Access-Profile:
Seq_No Action IP Address IP Mask Exact
5 permit 22.16.0.0 255.252.0.0 No
10 permit 192.168.0.0 255.255.192.0 Yes
15 deny any 255.0.0.0 No
20 permit 10.10.0.0 255.255.192.0 No
25 deny 22.44.66.0 255.255.254.0 Yes
