Example: Configuring multi-layer
DRNI+dual-active VLAN gateway+OSPF
Network configuration
As shown in Figure 1, the user network uses a three-layer architecture: core-aggregation-access. To
improve network availability, deploy two devices separately on the core layer, aggregation layer, and
access layer. Two devices on each layer form a DR system.
•
Device A and Device B form DR system 1, which acts as the access device and connects to
VM.
•
Device C and Device D form DR system 2, which acts as an aggregation device.
•
Device E and Device F form DR system 3, which acts as the core device and connects to
Server.
To meet the network access requirements of VM and Server, make sure the DR member devices on
the aggregation layer act as both the IPv4 gateway and IPv6 gateway of VM and the DR member
devices on the core layer act as both the IPv4 gateway and IPv6 gateway of Server. Run OSPF
between the DR member devices on the aggregation layer and DR member devices on the core
layer to ensure that they can reach each other at Layer 3.

Analysis
Device A and Device B are on the access layer. Device C and Device D are on the aggregation layer.
Device E and Device F are on the core layer.
On Device C and Device D, configure an IPv4 address and an IPv6 address for VLAN-interface 10,
which will act as the IPv4 gateway address and IPv6 gateway address of VM, respectively. Configure
an IPv4 address and an IPv6 address for VLAN-interface 20, which will act as the interconnect
interface to devices on the core layer.
On Device E and Device F, configure an IPv4 address and an IPv6 address for VLAN-interface 30,
which will act as the IPv4 gateway address and IPv6 gateway address of Server, respectively.
Configure an IPv4 address and an IPv6 address for VLAN-interface 20, which will act as the
interconnect interface to devices on the aggregation layer.
4
On Device C, Device D, Device E, and Device F, assign a DRNI virtual IP address to VLAN-interface
20, and enable OSPF to use the secondary IP addresses of interfaces to establish neighbor
relationships. On Device C and Device D, enable OSPF and OSPFv3 on VLAN-interface 10 and
VLAN-interface 20. On Device E and Device F, enable OSPF and OSPFv3 on VLAN-interface 20
and VLAN-interface 30. Configure Device C to use the DRNI virtual IP address of VLAN-interface 20
to establish OSPF/OSPFv3 neighbor relationships with Device D, Device E, and Device F. Configure
Device D, Device E, and Device F in the same way. Each device uses the DRNI virtual IP address to
establish OSPF/OSPFv3 neighbor relationships with the other three devices.

Traffic forwarding models
Underlay traffic characteristics
The forwarding model matrix provides the following characteristics of underlay traffic:
•
No.—Traffic number in the U-X-XXX format:
19
U—Underlay traffic.
X—Protocol number, which can be 4 (IPv4) or 6 (IPv6).
XXX—Traffic sequence number.
•
Traffic type—Type of underlay traffic, which can be IPv4 known unicast or IPv6 known unicast.
•
Direction—Direction of underlay traffic. The value is south-north, which indicates traffic from
the south to north.
•
Forwarding path—Nodes that underlay traffic traverses.
•
Traffic simulation—Traffic simulation method. Typically, a tester is used to simulate server
traffic.
•
Load—Traffic size, which can be light (less than 1000 flows) and heavy (more than 1000 flows).
•
Traffic direction to firewalls/LB—No firewalls or LBs are used in this example. This field is not
involved.
