1.3 Configuring IPv6 Multi-Topology

By configuring multi-topology on an IPv6 network, you can properly allocate network resources.
1.3.1 Before You Start
Before configuring IPv6 multi-topology, familiarize yourself with the usage scenario, complete
the pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
On a traditional IP network, only one unicast topology exists, and only one unicast forwarding
table exists on the forwarding plane. Services to the same destination IPv6 address share the
same per-hop forwarding behavior. This means that various end-to-end services (for example,
voice and data services) share the same physical link. Some links may be heavily congested
while other links are relatively idle. A solution to this problem is to divide a physical network
into different logical topologies for different services. Such a solution is called multi-topology.
As shown in
all devices on the network; other topology instances (such as the green topology, red topology,
and blue topology) just include some devices because they bear their respective services. By
deploying services (for example, voice and data services) in different topology instances as
required, you can isolate network resources on a network.
