Appendix A: Example Configuration
Configuring IP Routing
N o t e
A-24
As discussed for the Berlin router, the Mannheim router must tunnel the
multicast routing updates to the Berlin router.
To configure the routing protocols on the Mannheim router, you must com-
plete these steps.
1. Configure the loopback address for the router's OSPF ID.
Mannheim(config)# interface loopback 1
Mannheim(config-loop 1)# ip address 192.168.135.2 /24
2. Configure a tunnel interface to connect to Berlin. Use the PPP interface
for the PPPoE connection as the tunnel source, and, for the tunnel
destination, enter the IP address for the Berlin router's PPPoE connection.
Mannheim(config)# interface tunnel 1
Mannheim(config-tunnel 1)# ip address 192.168.191.2 /24
Mannheim(config-tunnel 1)# tunnel source ppp 2
Mannheim(config-tunnel 1)# tunnel destination 10.1.2.50
Mannheim(config-tunnel 1)# exit
3. Configure a default route for external traffic through the interface that
connects to the ISP router.
Mannheim(config)# ip route 0.0.0.0 /0 ppp 1
This default route must be entered manually even through the router also
receives a default route from the Berlin ABR. This is because the OSPF default
route directs the Mannheim router to send external traffic to the Berlin router.
However, the Mannheim router should use its own Internet connection for
external traffic.
4. Access the OSPF configuration mode context.
Mannheim(config)# router ospf
5. Place both of Mannheim's local networks in area 2, which also enables
OSPF on the Ethernet interfaces. Also enable OSPF for the network on
which the tunnel interface has its IP address (not its source or destina-
tion).
Mannheim(config-ospf)# network 192.168.128.0 0.0.0.255 area 2
Mannheim(config-ospf)# network 192.168.129.0 0.0.0.255 area 2
Mannheim(config-ospf)# network 192.168.191.0 0.0.0.255 area 2
6. Configure the local area as a stub area.
Mannheim(config-ospf)# area 2 stub
Mannheim(config-ospf)# exit
