Run the display ospf routing on the CE, and you can find that the routes from the CE to the
peer CE are learned and considered as the intra-area routes.

3.9 Configuring the Multi-VPN-Instance CE

This section describes how to separate services in a LAN by configuring OSPF multi-instance
on the CE.

3.9.1 Establishing the Configuration Task

3.9.2 Configuring the OSPF Multi-Instance on the PE
3.9.3 Configuring the OSPF Multi-Instance on the Multi-VPN-Instance CE
3.9.4 Disabling Loop Detection on the Multi-VPN-Instance CE
3.9.5 Checking the Configuration
3.9.1 Establishing the Configuration Task
Applicable Environment
The multi-VPN-instance CE is used in the LAN. You can isolate services by using OSPF multi-
instance on the CEs.
An OSPF process belongs to only one VPN instance; a VPN instance can run multiple OSPF
processes.
The multi-VPN-instance CE is a networking scheme that separates services by isolating routes.
To configure this scheme, disable the detection of routing loops.
