R0106-HP MSR Router Series Layer 3 - IP Services Configuration Guide(V7)

To enable the hosts on the two network segments to communicate with the external network through the

router, and to enable the hosts on the LAN to communicate with each other:

• Assign a primary IP address and a secondary IP address to GigabitEthernet 2/1/1 on the router.

• Set the primary IP address of the router as the gateway address of the PCs on subnet 172.16.1.0/24.

Set the secondary IP address of the router as the gateway address of the PCs on subnet

172.16.2.0/24.

Configuration procedure

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

<Router> system-view

[Router] interface gigabitethernet 2/1/1

[Router-GigabitEthernet2/1/1] ip address 172.16.1.1 255.255.255.0

[Router-GigabitEthernet2/1/1] ip address 172.16.2.1 255.255.255.0 sub

# Set the gateway address to 172.16.1.1 on the PCs attached to subnet 172.16.1.0/24, and to 172.16.2.1

on the PCs attached to subnet 172.16.2.0/24.

Verifying the configuration

# Verify the connectivity between a host on subnet 172.16.1.0/24 and the router.
