Network requirements

As shown in Figure 8, two routers on an intranet are connected to each other through serial interfaces

across a Digital Data Network. Each router connects to a LAN through an Ethernet interface.

To save IP addresses, configure the serial interfaces to borrow IP addresses from the Ethernet interfaces.

Configuration procedure

1. Configure Router A:

# Assign a primary IP address to GigabitEthernet 2/1/1.

<RouterA> system-view

[RouterA] interface gigabitethernet 2/1/1

[RouterA-GigabitEthernet2/1/1] ip address 172.16.10.1 255.255.255.0

[RouterA-GigabitEthernet2/1/1] quit

# Configure Serial 2/1/1 to borrow an IP address from GigabitEthernet 2/1/1.

[RouterA] interface serial 2/1/1

[RouterA-Serial2/1/1] ip address unnumbered interface gigabitethernet 2/1/1

[RouterA-Serial2/1/1] quit

# Configure a static route to the subnet attached to Router B, specifying Serial 2/1/1 as the

outgoing interface.
