Description
Using the routing-table limit command, you can configure a router as
Multi-VPN-Instance CE. Using the undo routing-table limit command, you can
remove the configuration.
OSPF multi-VPN-instance application is often run at the PE router, so the CE router
on which OSPF multi-VPN-instance application runs is called Multi-VPN-Instance
CE. Though they both support multi-VPN-instance application, Multi-VPN-Instance
CE does not necessarily support BGP/OSPF interoperability.
When OSPF procedures are bound with VPN instances, the default OSPF router
serves as PE router. This command will remove the default configuration and
change a router into Multi-VPN-Instance CE. Then OSPF procedure will set up all
peers again. DN bits and route-tag will not be check in routing calculation. To
prevent route loss, loop test function is disabled on PE routes. MGP/OSPF
interoperability is also disabled to save system resources.
After the display ospf brief command is executed successfully, the system prompts
the information “Multi-VPN-Instance enable on CE router”.
CAUTION: OSPF process will set up all peers again after this command is run.
Example
Configure OSPF procedure 100 as Multi-VPN-Instance CE.
[3Com-ospf-100] vpn-instance-capability simple
Restore the OSPF procedure 100 as PE.
