Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 642)

For example:
Brocade(config)# vrf blue6
Brocade(config-vrf-blue6)# rd 1:106
Brocade(config-vrf-blue6)# address-family ipv4
Error: has reached maximum system limit of maximum number of IPv4 routes
Brocade(config-vrf-blue6)#
Configuring VRF instances
A FastIron device can be configured with more than one VRF instance. You should define each VRF
instance before assigning an L3 interface to the VRF instance. The VRF instance name should be an
alphanumeric string of 1 to 255 characters.
NOTE
Using "overwrite" option while downloading configuration from tftp server to running-config as it will
lead to loss of all the vrf configurations when vrf is configured on the routing interface.
For example:
Brocade(config)# vrf customer-1
Brocade(config-vrf-customer-1)# exit-vrf
Brocade(config)#
On configuring vrf customer-1 , a VRF instance identified by customer-1 is configured, and the CLI
mode changes to VRF configuration mode. You can now use VRF configuration mode commands to
configure this VRF’s characteristics. Use exit-vrf to exit from the VRF configuration mode.
Configuring a route distinguisher
Each VRF instance is uniquely identified by a unique Route Distinguisher (RD) assigned to it. A route
distinguisher for a VRF instance gives a route associated with the VRF a unique identity. The RD is
prepended on the address being advertised, and provides overlapping client’s address space, a
unique identifier, when they are advertised to the backbone. This allows same IP address to be used
in different VRFs without conflicts. The RD format can be either:
• AS Number - Composed of AS number, followed by a ":" and a unique arbitrary number. For
example:
Brocade(config)# vrf customer-2
Brocade(config-vrf-customer-2)# rd 1:200
Brocade(config-vrf-customer-2)# exit-vrf
• IP address- Composed of the local IP address followed by a ":" and a unique arbitrary number. For
example:
Brocade(config)# vrf customer-1
Brocade(config-vrf-customer-1)# rd 1.1.1.1:100
Brocade(config-vrf-customer-1)# exit-vrf
Configuring IPv4 and/or IPv6 address families
Configuring a specific address family (AF), changes the mode of a VRF to the AF mode. This specific
AF mode will enable configuration commands that apply to that particular AF.
