Appendix A: Example Configuration
Configuring IP Routing
A-22
The Berlin router connects to the Mannheim router through a PPPoE session.
In this example, this connection is on the ADSL service provider's network,
which includes intervening routers that do not run OSPF. The Berlin and
Mannheim routers must establish a tunnel so that they can send each other
multicasts, including the multicasts for OSPF updates.
Complete these steps to configure the Berlin router:
1. Configure the loopback interface.
Berlin(config)# interface loopback 1
Berlin(config-loop 1)# ip address 192.168.127.1 /24
2. Configure the tunnel to Mannheim. The tunnel source is the PPP interface
for the PPPoE connection (PPP 2), and the tunnel destination is the IP
address on the Mannheim router's PPPoE connection.
Berlin(config)# interface tunnel 1
Berlin(config-tunnel 1)# ip address 192.168.191.1 /24
Berlin(config-tunnel 1)# tunnel source ppp 2
Berlin(config-tunnel 1)# tunnel destination 10.1.2.200
3. Configure the default route through the interface that connects to the ISP
router.
Berlin(config)# ip route 0.0.0.0 /0 ppp 1
4. Enter the OSPF configuration mode context.
Berlin(config)# router ospf
5. Advertise all networks on which the router has an interface, placing each
network in the correct area. The Ethernet interfaces should be in area 0
because the Berlin LAN is the network backbone. The network for a WAN
connection should be in the area for the connecting site, not in area 0.
Enable OSPF on the tunnel network that connects to Mannheim, not on
the PPPoE connection.
Berlin(config-ospf)# network 192.168.1.0 0.0.0.255 area 0
Berlin(config-ospf)# network 192.168.2.0 0.0.0.255 area 0
Berlin(config-ospf)# network 192.168.191.0 0.0.0.255 area 2
Berlin(config-ospf)# network 10.1.3.0 0.0.0.3 area 3
Berlin(config-ospf)# network 10.1.4.0 0.0.0.3 area 4
6. Configure areas 2, 3, and 4 as stub areas.
Berlin(config-ospf)# area 2 stub
Berlin(config-ospf)# area 3 stub
Berlin(config-ospf)# area 4 stub
