VRF Settings
- Route Distinguisher —An identifier attached to a route that indicates to which VPN or VPLS
routing instance it belongs. Each routing instance must have a unique distinguisher
associated with it. Each route distinguisher is a 6-byte value. These are the two different
values that can be used for the Route Distinguisher:
as-number:id—as-number is your assigned autonomous system (AS) number (a 2-byte
value) and id is any 4-byte value. The AS number can be in the range from 1 through
65,535.
ip-address:id—ip-address is an IP address in your assigned prefix range (a 4-byte value) and
id is any 2-byte value. The IP address can be any globally unique unicast address.
- VRF Target —If you configure the community only, default VRF import and export policies are
generated that accept and tag routes with the specified target community, helping to simplify
the VPN configuration process.
You can also explicitly configure VRF import and export policies using the import and export
options. You can configure the following for VRF Target:
community—Community name.
import community-name—The allowed communities to accept from neighbors.
export community-name—The allowed communities to send to neighbors.
- No VRF Advertise —Select this option so that this VRF does not advertise this instance to
remote PEs.
-
VRF Table Label —Check this option to map the inner label of a packet to a specific VPN
routing and forwarding (VRF) table. This allows the examination of the encapsulated IP
header.
