Defining a VRF routing instance
A single PE can contain one or more VRFs. Each of these VRFs must be defined separately on a PE.
A PE distributes routes and route packets to other members of the same VRF but not to other VRFs.
The VRF name can be any string that the user wants to define it as.
To define the VRF routing instance VPN1 on a PE, enter the following command.
Brocade(config)# vrf VPN1
Brocade(config-vrf-vpn1)# exit-vrf
Brocade(config)#
Syntax: [no] vrf vrf_name
Configures a VRF table on the device with the name vrf_name and puts the device in config-vrf
mode.
The vrf_name parameter specifies a name for the VRF being created.
Syntax: [no] exit-vrf
The exit-vrf command moves the user out of the VRF configuration mode for the VRF the user is
configuring.
Assigning a Route Distinguisher to a VRF
Each instance of a VRF must have a unique Route Distinguisher (RD) assigned to it. The RD is
prepended on any address being routed or advertised. The RD can be defined as either
ASN-relative or IP address-relative. Because the RD is unique to an instance of a VRF, it allows the
same IP address to be used in different VPNs without creating any conflict.
To assign a Route Distinguisher (RD) for a VRF based on the AS number 3 and the arbitrary
identification number 6, enter the following command.
Brocade(config-vrf)# rd 3:6
Syntax: [no] rd route_distinguisher
