15.3.7.1.2 Router 1 IP Configuration
Interface configuration:
interface Ethernet0/0
ip address 192.168.10.2 255.255.255.0
no ip directed-broadcast
!
interface Ethernet1/0
ip address 192.168.100.1 255.255.255.0
no ip directed-broadcast
GRE tunnel interface configuration:
interface Tunnel0
ip address 192.168.30.1 255.255.255.0
tunnel source Ethernet1/0
tunnel destination 192.168.100.2
Static routes with alternate paths at different costs:
ip classless
ip route 0.0.0.0 0.0.0.0 192.168.10.1
ip route 10.0.0.0 255.0.0.0 192.168.10.1
ip route 10.0.0.0 255.0.0.0 Tunnel0 10
ip route 192.168.100.2 255.255.255.255 192.168.100.80
ip route 192.168.100.77 255.255.255.255 Tunnel0 20
ip route 192.168.100.78 255.255.255.255 Tunnel0 10
ip route 192.168.100.79 255.255.255.255 Tunnel0 10
Note that the host routing path to the peer DCN router (Router 2, 192.168.100.2) points to the
ONS 15454 network (by 192.168.100.80). This is required to set up the GRE tunnel. In this
configuration, only the external route to 10.0.0.0 (that includes the NOC network) is overloaded with the
alternate path. However, overloading of the last-resort route could also occur.
