ACI EIGRP Routing for External Layer 3 Connectivity

LAB: ACI EIGRP Routing for External Layer 3 Connectivity

Topology: 

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

TASK1: Configure EIGRP Interface Policy with following details:

• NAME: DCL-EIGRP-INTERFACE-POLICY
• Split-Horizon: Checked
• Control state – passive : Unchecked
• Control State – Self Next Hop – Checked

TASK 2: Create External Routed Network with following details:

• Create External Routed outside network with name DCL-EIGRP-EXTERNAL-ROUTED-NW on VRF DCLessons_VRF and attach the External Routed Domain you created in previous LAB named DCL-EXTERNAL-ROUTED-DOMAIN.
• Enable EIGRP with AS number 10
• Use Node profile named DCL-EIGRP-NODE-PROFILE with Node ID 102, Router-ID 102.11.1.2 and Router-ID as Loopback Interface: checked
• Create EIGRP Interface Profile named DCL-EIGRP-INT-PROFILE, use EIGRP Interface Policy created in TASK 1.
• Create SVI for Leaf 102/e1/5, encap vlan 112 with ip address 100.11.12.2/24
• Create External EPG DCL-EIGRP-EXTERNAL-EPG with subnet 11.2.3.0/24
• Create a Contracts between named DCL-CONTRACT-EIGRP 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 EIGRP Interface Policy with following details:

• NAME: DCL-EIGRP-INTERFACE-POLICY
• Split-Horizon: Checked
• Control state – passive : Unchecked
• Control State – Self Next Hop – Checked

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

TASK 2: Create External Routed Network with following details:

Create External Routed outside network with name DCL-EIGRP-EXTERNAL-ROUTED-NW on VRF DCLessons_VRF and attach the External Routed Domain you created in previous LAB named DCL-EXTERNAL-ROUTED-DOMAIN. Enable EIGRP with AS 10

• 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-EIGRP-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 EIGRP and AS 10

Use Node profile named DCL-EIGRP-NODE-PROFILE with Node ID 102, Router-ID 102.11.1.2 and Router-ID as Loopback Interface: checked

• Click + sign on Node and Interface Profile and create as per following task mentioned DCL-EIGRP-NODE-PROFILE click on + sign on Node ID and Provide Node ID 102
• check Router-ID as Loopback Interface

• Create EIGRP Interface Profile named DCL-EIGRP-INT-PROFILE, use EIGRP Interface Policy created in TASK 1.

Click + on EIGRP Interface Profile and use the value given in above task.
