Use the undo summary command to cancel this summary.
By default, BGP does not perform the auto summary to subnet routes.
After auto summary is enabled, BGP cannot receive the subnet routes imported from
IGP. Using this feature, you can reduce the amount of routing information.

Syntax
vpn-instance-capability simple
undo vpn-instance-capability
View
OSPF protocol view
Parameter
None
Description
Use the vpn-instance-capability simple command to configure a router as
Multi-VPN-Instance CE.
Use the undo vpn-instance-capability command to cancel the configuration.
OSPF multi-VPN-instance is often run at a PE router. So a CE router, on which OSPF
multi-VPN-instance runs, is called Multi-VPN-Instance CE. Though they both support
multi-VPN-instance, Multi-VPN-Instance CE does not necessarily support BGP/OSPF
interoperability.
When an OSPF process is bound to a VPN instance, the default OSPF router is PE
router. This command will remove the default setting and change a router into a
Multi-VPN-Instance CE. . After the configuration, OSPF processes will reestablish all its
neighbors. DN bits and Route-tag will not be checked in routing calculation. To prevent
route loss, routing loop test 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.
