Configuring Route Related Attributes of a VPN Instance

The control process of VPN route advertisement is as follows:
When a VPN route learned from a CE gets redistributed into BGP, BGP associates it with a VPN
target extended community attribute list, which is usually the export target attribute of the VPN
instance associated with the CE.
The VPN instance determines which routes it can accept and redistribute according to the
import-extcommunity in the VPN target.
The VPN instance determines how to change the VPN targets attributes for routes to be
redistributed according to the export-extcommunity in the VPN target.
