Chapter 64 Configuring Routing Policies

BGP Routing Policy Page

•(Device view) Select Platform > Routing > BGP from the Policy selector, then click the

Redistribution tab in the work area.

•(Policy view) Select Router Platform > Routing > BGP from the Policy Type selector. Select an

existing policy or create a new one, and then click the Redistribution tab.

The BGP Redistribution tab is displayed. See Table64-3 on page 64-7 for a description of the fields on

this tab.

Step 2 On the BGP Redistribution tab, select a row from the BGP Redistribution Mappings table, then click

Edit, or click Add to create a mapping. The BGP Redistribution Mapping dialog box appears. See

Table 64-4 on page64-8 for a description of the fields in this dialog box.

Step 3 Select the protocol whose routes you want to redistribute into BGP.

Note You can create a single mapping for each static route, RIP route, EIGRP AS, and OSPF process.

Step 4 (Optional) Modify the default metric (cost) of the redistributed routes. The metric determines the priority

of the routes.

Step 5 Click OK to save your definitions locally on the client and close the dialog box. The redistribution

mapping appears in the Redistribution Mapping table in the BGP Redistribution tab.

BGP Routing Policy Page

Border Gateway Protocol (BGP) is an exterior gateway protocol (EGP) that performs routing between

multiple autonomous systems or domains and exchanges routing and reachability information with other

BGP systems. BGP is used to exchange routing information on the Internet and is the protocol used

between Internet service providers.

You can configure BGP routing policies from the following tabs on the BGP Routing page:

•BGP Page—Setup Tab, page64-4

•BGP Page—Redistribution Tab, page64-6

For more information, see BGP Routing on Cisco IOS Routers, page 64-1.

Navigation Path

•(Device view) Select Platform > Routing > BGP from the Policy selector.

•(Policy view) Select Router Platform > Routing > BGP from the Policy Type selector. Right-click

BGP to create a policy, or select an existing policy from the Shared Policy selector.

Use the BGP Setup tab to define the number of the autonomous system (AS) in which the selected router

is located. You must then define which networks are included in the AS and which networks are the

internal and external neighbors of the router. Additionally, you can enable or disable options that govern

the interaction between BGP and Interior Gateway Protocols (IGPs), such as OSPF and EIGRP. Use a

third option to enable the logging of messages from BGP neighbors.
