It provides fallback for IE8.

An administrator binds VLAN interface 10 to VPN instance "TenantA" on an HP Comware switch by using this configuration:
interfaceVlan-interface 10
ip address 10.1.10.1 255.255.255.0
How does the administrator's action affect the interface IP address?

The interface loses the IP address, and the administrator must configure the IP address on this interface again. ✘ The IP address remains 10.1.10.1/24 but is extended with the Route Distinguisher (RD) and can now be assigned to an interface in another VPNinstance. ✘ The interface loses the IP address and the administrator must map the interface to 10.1 10.1/24 from the VPN instance context ✘ The IP address remains 10.1 10.1/24. but now this subnet can also be assigned to an interface in another VPN instance. ✔
