Aruba CX OSPF Config Example

 Building OSPF in Aruba CX switches.

Version 10.05.0020

DistMain-Switch

vlan 1

vlan 2

vlan 6

vlan 830

    name OSPF-Dist-HS

vlan 831

    name OSPF-Dist-MS

//  vlan 1,2,6 are the local vlans

interface vlan 1

    ip address 10.129.31.254/22

interface vlan 2

    ip address 10.129.47.254/22

interface vlan 6

    ip address 10.129.3.254/22

//  vlan 830,831 are the OSPF networks that will distribute the routes.

interface vlan 830

    description OSPF-Dist-HS

    ip address 10.130.253.1/27

    ip ospf 1 area 0.0.0.0

interface vlan 831

    description OSPF-Dist-MS

    ip address 10.131.253.1/27

    ip ospf 1 area 0.0.0.0

// ospf config..... we are redistributing ALL connected routes on this switch.... If you want to only redistribute certain routes you would need to do a route-map.. see bottom of page for that example.

route ospf 1

    rotuer-id 1.1.1.1

    redistribute connected

    area 0.0.0.0

interface 1/1/2

    no shutdown

    no routing

    vlan trunk native 1

    vlan trunk allowed 830

interface 1/1/3

    no shutdown

    no routing

    vlan trunk native 1

    vlan trunk allowed 831

HS-Main-Switch

vlan 2

vlan 830

interface vlan 2

    ip address 10.130.47.254/22

interface vlan 830

    ip address 10.130.253.2/27

    ip ospf 1 area 0.0.0.0

router ospf 1

    router-id 1.1.1.2

    redistribute connected

    area 0.0.0.0

interface 1/1/2

    no shutdown

    no routing

    vlan trunk native 1

    vlan trunk allowed 830

MS-Main-Switch

vlan 6

vlan 831

interface vlan 6

    ip address 10.131.3.254/22

interface vlan 831

    ip address 10.131.253.2/27

    ip ospf 1 area 0.0.0.0

router ospf 1

    router-id 1.1.1.3

    redistribute connected

    area 0.0.0.0

At this point you should be able to see your ospf peers come up.

"show ip ospf neighbors"

"show ip route ospf"

Route-Map

//  If you would like to only advertise certain routes through OSPF then route-map will be the command to use. 

route-map Allow-Vlan permit seq 10

match interface vlan1

exit

route-map Allow-Vlan permit seq 20

match interface vlan2

exit

Router ospf 1

router ospf redistribute route-map Allow-Vlan

//  This will only allow vlan 1 and 2 to be advertised into OSPF for redistribution.... if you add more vlan's and want to advertise them you will need to add them to the route-map.

Aruba CX BGP Setup Example

 Very simple setup of BGP and advertising networks.

Version 10.05.0020

Switch 1

1.  Create your Vlan interfaces

vlan 100

    name BGP-1

interface vlan 100

    ip address 20.20.20.254/24

2.  Set up interface

interface 1/1/5

    no shutdown

    no routing

    vlan trunk native 1

    vlan trunk allowed 100

3.  Set up BPG

router bgp 1234

    bgp router-id 20.20.20.254

    neighbor 20.20.20.253 remote-as 12345

    address-family ipv4 unicast

        neighbor 20.20.20.253 activate

        exit

    exit

//  The route-id we are using as the "interface vlan id"... this does not have to be like this... you could set this up as 1.1.1.1 if you would like.  Keep in mind though that if you change it the BGP setup will have to rebuilt itself.

//  The "neighbor" will be the other side of our BGP peer

//  neighbor "20.20.20.253 activate"  will actually enable the routes to transverse between BGP peers

Switch 2

1.  Create your Vlan interfaces

vlan 100

    name BGP-1

vlan 200

    name test-vlan

interface vlan 100

    ip address 20.20.20.253/24

interface vlan 200

    ip address 30.0.0.254/24

2.  Set up interface

interface 1/1/5

    no shutdown

    no routing

    vlan trunk native 1

    vlan trunk allowed 100

interface 1/1/7

    no shutdown

    no routing

    vlan trunk native 1

    vlan trunk allowed 200

3.  Set up BPG

router bgp 12345

    bgp router-id 20.20.20.253

    neighbor 20.20.20.254 remote-as 1234

    address-family ipv4 unicast

        neighbor 20.20.20.254 activate

        network 30.0.0.0/24

        exit

    exit

//  Notice that we have added "network 30.0.0.0/24" to our BGP setup... this is the network that we are advertising out through BGP.  If we go back to Switch 1 we can run "show ip route bgp" and we will see that this network is being advertised through BGP and we are able to ping it.
