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 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.
