Chapter 6: Routing Policy Configuration Guide
6 - 32 SSR User Reference Manual
For all examples in this section, refer to the configuration shown in Figure 3 on page
6 - 25.
The following configuration commands for router R1:
• Determine the IP address for each interface
• Specify the static routes configured on the router
• Determine its OSPF configuration
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
! Create the various IP interfaces.
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
interface create ip to-r2 address-netmask 120.190.1.1/16 port et.1.2
interface create ip to-r3 address-netmask 130.1.1.1/16 port et.1.3
interface create ip to-r41 address-netmask 140.1.1.1/24 port et.1.4
interface create ip to-r42 address-netmask 140.1.2.1/24 port et.1.5
interface create ip to-r6 address-netmask 140.1.3.1/24 port et.1.6
!+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
! Configure default routes to the other subnets reachable through R2.
!+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
ip add route 202.1.0.0/16 gateway 120.1.1.2
ip add route 160.1.5.0/24 gateway 120.1.1.2
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
! OSPF Box Level Configuration
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
ospf start
ospf create area 140.1.0.0
ospf create area backbone
ospf set ase-defaults cost 4
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
! OSPF Interface Configuration
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
ospf add interface 140.1.1.1 to-area 140.1.0.0
ospf add interface 140.1.2.1 to-area 140.1.0.0
ospf add interface 140.1.3.1 to-area 140.1.0.0
ospf add interface 130.1.1.1 to-area backbone
Exporting all interface and static routes to OSPF
Router R1 has several static routes. We would export these static routes as type-2
OSPF routes. The interface routes would redistributed as type 1 OSPF routes.
1. Create a OSPF export destination for type-1 routes since we would like to redis-
tribute certain routes into OSPF as type 1 OSPF-ASE routes.
