Huawei quidway s7700 - Checking the Configuration; Configuring a Multi-VPN-Instance CE; Establishing the Configuration Task

3.9.5 Checking the Configuration
After configuring an OSPF sham link, you can view information about the routing table on the
CE, the nodes through which packets are sent, and established and non-established sham links.
Prerequisite
The configurations of the OSPF sham link function are complete.
Procedure
l Run the display ip routing-table vpn-instance vpn-instance-name command to check the
routing table of the specified VPN instance on the PE.
l Run the display ip routing-table command to check the routing table on the CE.
l Run the tracert host command to check the path of the data transmitted to the peer CE On
the CE.
l Run the display ospf process-id sham-link [ area area-id ] command to check the setup
state of the sham-link on the PE.
l Run the display ospf routing command to check the routes discovered by OSPF on the
CE.
----End
Example
Run the display ip routing-table vpn-instance command. You can find the routes from the PE
to the peer CE is the OSPF routes that pass through the private network rather than the BGP
routes that pass through the backbone network.
Run the display ip routing-table and the tracert commands on the CE. You can find the VPN
traffic from the CE to the peer is forwarded through the backbone network.
Run the display ospf process-id sham-link command on the PE. You can find the OSPF
neighbor status between the PE and the peer CE is Full.
Run the display ospf routing on the CE. You can find the routes from the CE to the peer CE is
learned as the intra-area routes.
3.10 Configuring a Multi-VPN-Instance CE
By using OSPF multi-instance on CEs, you can implement service isolation on the LAN.
3.10.1 Establishing the Configuration Task
Before configuring a multi-VPN-instance CE, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the data required for the
configuration. This will help you complete the configuration task quickly and accurately.
Applicable Environment
The multi-VPN-instance CE is used in the LAN. You can implement service isolation through
the multiple OSPF instances on the CE devices.
