Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 404)

Layer 3 configurations are applicable to service VFs, by means of existing interface ve commands.
Each virtual Ethernet (VE) interface is mapped to a service VF, and all VE interfaces share the router's
MAC address. A VE interface can be assigned to a VRF instance, with per-VRF OSPF instances
exchanging routes between RBridges in that VRF instance. Virtual Router Redundancy Protocol
(VRRP) provides high availability.
Do the following to configure Layer 3 service VF features.
1. Create a service VF and add it to the trunk port with a C-TAG.
switch(config)# interface vlan 5000
switch(config)# interface te 3/1/1
switch(conf-if-te-3/1/1)# switchport
switch(conf-if-te-3/1/1)# switchport mode trunk
switch(conf-if-te-3/1/1)# switchport trunk allowed vlan add 5000 ctag 50
2. Enable VRF and VRRP on an RBridge.
switch(config)# rbridge-id 3
switch(config-rbridge-id-3)# protocol vrrp
3. Create a VRF instance and set OSPF routing parameters.
NOTE
BGP is also supported in the appropriate context.
switch(config)# ip vrf VRF_CUST1
a) Use the rd (Route Distinguisher) command to assign an administrative number.
switch(config-vrf-CUST1)# rd 10.1.1.1:1
b) Set the OSPF address family to IPv4.
switch(config-vrf-CUST1)# address-family ipv4
switch(config-vrf-CUST1)# exit
c) Return to config mode.
switch(config-vrf-CUST1)# exit
4. Create the VE interface on the service VF and configure VRF forwarding and VRRP.
a) Configure forwarding for a VRF instance.
switch(config-ve-5000)# ip vrf forwarding VRF_CUST1
b) In RBridge ID configuration mode, create a virtual Ethernet interface, and assign the
service VF and IP address. Be sure to enable the interface.
switch(config)# rbridge-id 3
switch(config-rbridge-id-3)# interface ve 5000
switch(config-ve-5000)# ip address 10.1.1.1/24
switch(config-ve-5000)# no shutdown
c) Create a VRRP group and assign a virtual IP address.
switch(config-ve-5000)# vrrp-group 22
switch(config-vrrp-group-22)# virtual-ip 10.1.1.1
Upgrading and downgrading firmware with Virtual Fabrics
Refer to Virtual Fabrics upgrade and downgrade considerations on page 377 The following applies
where there are no Brocade VDX 6720 and VDX 6730 series RBridges in the fabric.
1. Do the following to upgrade to a VF-enabled fabric.
a) Configure the fabric in management cluster mode.
b) Perform an ISSU on all VF-capable RBridges; the fabric reaches a VF-capable state.
c) In global configuration mode, issue the vcs virtual-fabric enable command. The fabric
reaches a VF-enabled state.
NOTE
Step 1b and Step 1c are nondisruptive. Existing 802.1Q traffic is forwarded without disruption.
2. Do the following to downgrade from a VF-enabled fabric.
