LAB: ACI OSPF Routing for External Layer 3 Connectivity

Topology: 

TASK: Follow the below following task to configure OSPF Routing to reach External Network subnets which is behind External Switch.

TASK1: Configure OSFP Interface Policy with following details:

  • NAME: DCL-OSPF-INTERFACE-POLICY
  • Network Types: Broadcast
  • Interface Control – Advertise Subnets: Checked

TASK 2: Create External Routed Network with following details:

  • Create External Routed outside network with name DCL-OSPF-EXTERNAL-ROUTED-NW on VRF DCLessons_VRF and attach the External Routed Domain you created in previous LAB named DCL-EXTERNAL-ROUTED-DOMAIN.
  • Enable OSPF with AREA ID 2, and Area Type: NSSA
  • Use Node profile named DCL-OSPF-NODE-PROFILE with Node ID 102, Router-ID 102.11.1.2 and Router-ID as Loopback Interface: checked
  • Create OSPF Interface Profile named DCL-OSPF-INT-PROFILE, use authentication type MD5 and key DCLESSONS123, use OSPF Interface Policy created in TASK 1.
  • Create SVI for Leaf 102/e1/5, encap vlan 112 with ip address 100.11.11.2/24
  • Create External EPG DCL-OSPF-EXTERNAL-EPG with subnet 11.2.2.0/24
  • Create a Contracts between named DCL-CONTRACT-OSPF with subject name SUBJECT-ANY and enable Apply both direction and Reserve filter ports checked also use DCL-FILTER-ANY filter.
  • Use the above Contracts on Web_EPG on provided side and External EPG on Consumer side.
  • Associate External Routed network to bridge Domain DCLessons_DB and advertise the subnets to External Routed Network.

Solution:

TASK1: Configure OSFP Interface Policy with following details:

  • NAME: DCL-OSPF-INTERFACE-POLICY
  • Network Types: Broadcast
  • Interface Control – Advertise Subnets: Checked

Expand Tenant DCLessons | Networking | Protocol Policies | OSPF | OSPF Interface. Right-click the OSPF Interface and then select Create OSPF Interface Policy with above task details.

TASK 2: Create External Routed Network with following details:

Create External Routed outside network with name DCL-OSPF-EXTERNAL-ROUTED-NW on VRF DCLessons_VRF and attach the External Routed Domain you created in previous LAB named DCL-EXTERNAL-ROUTED-DOMAIN. Enable OSPF with AREA ID 2, and Area Type: NSSA

  • DCLessons | Networking | External Routed Networks.
  • Right-click the External Routed Networks and then select Create Routed Outside
  • In the Create Routed Outside wizard Create External Routed outside network with name DCL-OSPF-EXTERNAL-ROUTED-NW on VRF DCLessons_VRF and attach the External Routed Domain you created in previous LAB named DCL-EXTERNAL-ROUTED-DOMAIN.
  • Select the OSPF and create ID 2 and Area Type NSSA.
