Parameter
route-distinguisher: Configures a VPN IPv4 prefix by adding an 8-byte value to a VPN
IPv4 prefix.
Description
Use the route-distinguisher command to configure RD for an MPLS VPN instance. A
VPN-instance cannot run until it is configured with an RD.
A route distinguisher (RD) creates route and forwarding list for a VPN and specifies the
default route identifier. Add an RD to the beginning of a specific IPv4 prefix to make it a
globally unique VPN IPv4 prefix.
If an RD is associated with an autonomous system number (ASN), it is composed of the
ASN and an arbitrary number; if the RD is associated with an IP address, it is a
combination of the IP address and an arbitrary number.
RD has the following formats:
16-bit ASN (can be 0 here): A custom 32-bit number, for example, 101:3.
32-bit IP address (can be 0.0.0.0 here): A custom 16-bit number, for example,
192.168.122.15:1.
