While configuring an AF, you can optionally configure the maximum routes that are associated with the
AF. If the max-route is not configured, the default value of maximum routes will be configured for the
VRF instance based on the system-max value of ip-route-vrf or ip6-route-vrf .

To configure address families, enter the following commands:

Brocade(config)# vrf customer-1

Brocade(config-vrf-customer-1)# rd 1.1.1.1:100

Brocade(config-vrf-customer-1)# address-family ipv4

Brocade(config-vrf-customer-1-ipv4)# exit-address-family

Brocade(config-vrf-customer-1)# exit-vrf

Brocade(config)#

Brocade(config)# vrf customer-2

Brocade(config-vrf-customer-2)# rd 1:200

Brocade(config-vrf-customer-2)# address-family ipv4 max-route 2000

Brocade(config-vrf-customer-2-ipv4)# exit-address-family

Brocade(config-vrf-customer-2)# exit-vrf

Brocade(config)#

Syntax: [no] address-family { ipv4 | ipv6 } [ max-route max-value ]

When you specify the maximum routes of an AF using max-route , the number of max-routes cannot
change once it is configured. To change the number of routes, you must delete the AF and recreate the
AF configuration. Attempting to reset the maximum number of routes results in the following error:

Brocade(config-vrf-customer1)# address-family ipv4 max-route 2000

Error: IPv4 Address Family is already configured with max-route 1000

Brocade(config-vrf-customer1)#

Configuring routing protocols for new Multi-VRF instance

Configure Multi-VRF specific parameters under the specific address family.

For IPv4 address family, configure:

• static route
• static arp
• igmp
• multicast

For IPv6 address family, configure:

• static route
• ipv6 neighbor
• multicast

Assigning a VRF routing instance to an L3 interface

After configuring a VRF instance on a FastIron router, the VRF instance must be assigned to one or
more Layer 3 interface (physical or virtual Ethernet interfaces). When a VRF instance is assigned to an
interface, all IP addresses are deleted, and will trigger cache deletion, route deletion and associated
cleanup. You must re-configure the IP address and interface properties after assigning a VRF instance
to the L3 interface.

The following example assigns VRF customer-1 to interface 7/1:

Brocade(config-if-e1000-7/1)# vrf forwarding customer-1

Warning: All IPv4 and IPv6 addresses (including link-local) on this interface have

been removed

Brocade(config-if-e1000-7/1)#

Syntax: [no] vrf forwarding vrf-name
