Command Reference Guide
vrf <name> route-distinguisher
Use the vrf route-distinguisher command to create a nondefault VPN routing and forwarding (VRF)
instance and assign it a route distinguisher. Use the no vrf command to remove all VRF instances
configured on the system. Use the no vrf route-distinguisher command to destroy the VRF instance and
any commands configured on the VRF.
vrf <name> route-distinguisher as-2byte <ASN:nn>

Release R10.1.0
Functional Notes
The route distinguisher 0:0 or 0.0.0.0:0 is reserved for the default (unnamed) VRF instance and cannot be
reassigned.
VRF on AOS products allows a single physical router to be partitioned into multiple virtual routers. Each
router instance has its own route table and interface assignments. Beginning with Release 16.1, all AOS
routers supporting multiple VRF instances (multi-VRF) have an unnamed default VRF instance regardless
of whether multi-VRF is configured.

Variations of this command include:
Specifies the name of the VRF instance. Valid range is up to 79
alphanumeric characters.
Specifies the autonomous system number (ASN)-relative route
distinguisher as a 16-bit AS number (ASN) and a 32-bit arbitrary number
(nn).
Specifies the ASN-relative route distinguisher as a 32-bit AS number (ASN)
and a 16-bit arbitrary number (nn).
Specifies an IPv4 address-relative route distinguisher, which consists of an
IPv4 address and a 16-bit arbitrary number (nn). IPv4 addresses should be
expressed in decimal dotted notation (for example, 10.10.10.1).
Command was introduced.
Command syntax was changed to remove the ip keyword for IPv6 support
in ADTRAN internetworking products. In addition, the as-2byte, as-4byte,
and ip <ipv4 address:nn> parameters were added.
Command syntax was changed to remove the ip keyword for IPv6 support
in ADTRAN voice products. In addition, the as-2byte, as-4byte, and ip
<ipv4 address:nn> parameters were added.
