RD ROUTE DISTINGUISHER

rd (route distinguisher)

Overview This command creates a Route Distinguisher (RD). The RD forms part of the route
table creation process for a VRF instance and is implemented only when using BGP
routing.
rd {<ASN:n>|<ip-address:n>}
Syntax
CAUTION
deleting the VRF instance to which it is assigned. Therefore, it is important that you
carefully enter the correct value for the RD.
NOTE
formal ASN number assigned to your BGP network, you should enter this value.
Alternatively; because the Route Distinguisher has limited functionality in VRF-lite, you
can use an unofficial value for your ASN when configuring this particular command.
Mode VRF Configuration
Usage For the implementation of VRF-lite installed on your switch, this command has
little practical functionality. However, the switch does check certain components
of the RD that you enter. For this reason, the RD syntax must comply with the
structural formats defined above, and each value that you assign to a VRF instance
must be unique on the switch. Good networking practice is to use common values
for the RD and RT within a VRF instance.
Default No default RD is configured.
Example To create an RD 100:2 that is associated with VRF "red" use the following
commands:
awplus#
awplus(config)#
awplus(config-vrf)#
