Usage guidelines
An RD is used to create the routing and FIB of a VPN. By prefixing an RD to an IPv4 prefix, you get a VPN
IPv4 prefix unique globally.
No RD is configured by default; you must configure an RD for each VPN instance.
A VPN instance takes effect only after you configure an RD for it.
Once you configure an RD for a VPN, you cannot remove the association.
You cannot change an RD directly; you can only delete the VPN instance, and then re-create the VPN
instance and re-configure a new RD.

# Configure the RD of VPN instance vpn1.
