Configuring the QFX Series Switch for the Contrail Cloud Platform in a Centralized Deployment

1. Configure the IP address of the Ethernet management port. For example:
   user@switch# set interfaces vme unit 0 family inet address 172.16.70.251/24
2. Configure integrated routing and bridging (IRB). For example:
   user@switch# set interfaces irb unit 80 family inet address 172.16.80.254/24
3. Configure a link aggregation group (LAG) for each pair of server ports. For example:
   user@switch# set interfaces xe-0/0/0 ether-options 802.3ad ae0user@switch# set interfaces xe-0/0/20 ether-options 802.3ad ae0 user@switch# set interfaces ae0 mtu 9192 user@switch# set interfaces ae0 aggregated-ether-options lacp activeuser@switch# set interfaces ae0 aggregated-ether-options lacp periodic fast user@switch# set interfaces ae0 unit 0 family ethernet-switching interface-mode access user@switch# set interfaces ae0 unit 0 family ethernet-switching vlan members data
   user@switch# set interfaces xe-0/0/1 ether-options 802.3ad ae1 user@switch# set interfaces xe-0/0/21 ether-options 802.3ad ae1 user@switch# set interfaces ae1 mtu 9192 user@switch# set interfaces ae1 aggregated-ether-options lacp activeuser@switch# set interfaces ae1 aggregated-ether-options lacp periodic fastuser@switch# set interfaces ae1 unit 0 family ethernet-switching interface-mode access user@switch# set interfaces ae1 unit 0 family ethernet-switching vlan members data
   user@switch# set interfaces xe-0/0/2 ether-options 802.3ad ae2 user@switch# set interfaces xe-0/0/22 ether-options 802.3ad ae2user@switch# set interfaces ae2 mtu 9192 user@switch# set interfaces ae2 aggregated-ether-options lacp activeuser@switch# set interfaces ae2 aggregated-ether-options lacp periodic fastuser@switch# set interfaces ae2 unit 0 family ethernet-switching interface-mode accessuser@switch# set interfaces ae2 unit 0 family ethernet-switching vlan members data
   user@switch# set interfaces xe-0/0/3 ether-options 802.3ad ae3 user@switch# set interfaces xe-0/0/23 ether-options 802.3ad ae3 user@switch# set interfaces ae3 mtu 9192 user@switch# set interfaces ae3 aggregated-ether-options lacp active user@switch# set interfaces ae3 aggregated-ether-options lacp periodic fastuser@switch# set interfaces ae3 unit 0 family ethernet-switching interface-mode access user@switch# set interfaces ae3 unit 0 family ethernet-switching vlan members data

   user@switch# set interfaces xe-0/0/5 ether-options 802.3ad ae5user@switch# set interfaces xe-0/0/25 ether-options 802.3ad ae5user@switch# set interfaces ae5 mtu 9192 user@switch# set interfaces ae5 aggregated-ether-options lacp active user@switch# set interfaces ae5 aggregated-ether-options lacp periodic fast user@switch# set interfaces ae5 unit 0 family ethernet-switching interface-mode access user@switch# set interfaces ae5 unit 0 family ethernet-switching vlan members data
   user@switch# set interfaces xe-0/0/6 ether-options 802.3ad ae6user@switch# set interfaces xe-0/0/26 ether-options 802.3ad ae6user@switch# set interfaces ae6 mtu 9192 user@switch# set interfaces ae6 aggregated-ether-options lacp active user@switch# set interfaces ae6 aggregated-ether-options lacp periodic fast user@switch# set interfaces ae6 unit 0 family ethernet-switching interface-mode access user@switch# set interfaces ae6 unit 0 family ethernet-switching vlan members data
   user@switch# set interfaces xe-0/0/7 ether-options 802.3ad ae7user@switch# set interfaces xe-0/0/27 ether-options 802.3ad ae7user@switch# set interfaces ae7 mtu 9192 user@switch# set interfaces ae7 aggregated-ether-options lacp active user@switch# set interfaces ae7 aggregated-ether-options lacp periodic fast user@switch# set interfaces ae7 unit 0 family ethernet-switching interface-mode access user@switch# set interfaces ae7 unit 0 family ethernet-switching vlan members data
   user@switch# set interfaces xe-0/0/8 ether-options 802.3ad ae8user@switch# set interfaces xe-0/0/28 ether-options 802.3ad ae8user@switch# set interfaces ae8 mtu 9192 user@switch# set interfaces ae8 aggregated-ether-options lacp active user@switch# set interfaces ae8 aggregated-ether-options lacp periodic fast user@switch# set interfaces ae8 unit 0 family ethernet-switching interface-mode access user@switch# set interfaces ae8 unit 0 family ethernet-switching vlan members data
4. Configure a VLAN for data transmission. For example:
   user@switch# set vlans data vlan-id 80 user@switch# set vlans data l3-interface irb.80
5. Configure OSPF routing. For example:
   user@switch# set interfaces irb unit 80 family inet address 172.16.80.254/24 user@switch# set protocols ospf area 0.0.0.0 interface irb.80 passive
6. Configure the interface that connects to the MX Series router. For example:
   user@switch# set interfaces xe-0/0/46 ether-options 802.3ad ae9 user@switch# set interfaces xe-0/0/47 ether-options 802.3ad ae9
   user@switch# set interfaces ae9 aggregated-ether-options lacp activeuser@switch# set interfaces ae9 aggregated-ether-options lacp periodic fast user@switch# set interfaces ae9 unit 0 family inet address 172.16.10.253/24
   user@switch# set protocols ospf area 0.0.0.0 interface ae9.0
