ACI Extend Bridge Domain by External Layer 2 Connection

LAB: ACI Extend Bridge Domain by External Layer 2 Connection

Topology: 

TASK: Follow the below following task to configure External Layer 2 Connectivity and extending Bridge Domain.

TASK1: Configure AEP and Switch Policy on which External Switch is connected.

• Create the Attachable Access Entity Profile named DCL-L2-AEP and associate Interface policy Group named DCL-L2-POLICY-GROUP and call 1G Link Level Policy, CDP enable policy, LLDP enable Policy create Interface Profile named DCL-L2-INTERFACE-PROFILE and associate with it.
• Configure Switch Profile Policy and select Leaf 102 and port 1/10 over which external Switch is connected.

TASK2: Configure VLAN Pool for External Bridge Domain.

• Configure VLAN Pool named DCL-EXTERNAL-BD-VLAN-POOL
• Use static allocation and use VLAN 211.

TASK3: Configure External Bridge Domain or Layer 2 Domain.

• Configure Layer 2 Bridge Domain named DCL-EXTERNAL-BRIDGE DOMAIN
• Associate AEP DCL-L2-AEP with it
• Use VLAN Pool DCL-EXTERNAL-BD-VLAN-POOL in it.

TASK4: Configure External Bridge Network.

• Configure External Bridge Network or Layer 2 Outside network named DCL-EXTERNAL-BRIDGE-NET
• Associate Layer 2 Bridge Domain named DCL-EXTERNAL-BRIDGE DOMAIN
• Associate Bridge Domain DCLessons_BD with encap 211
• Use Path type Port and select path 102/eth1/10
• Create External network EPG named DCL-EXTERNAL-EPG

TASK5: Configure Contracts between Web_EPG and External Network

• Use Contracts named DCLessons-Contract-ANY which was created earlier in section as provided side.
• And on EPG named DCL-EXTERNAL-EPG use contracts DCLessons-Contract-ANY at consumer side.

Solution:

TASK1: Configure AEP and Switch Policy on which External Switch is connected.

• Create the Attachable Access Entity Profile named DCL-L2-AEP and associate Interface policy Group named DCL-L2-POLICY-GROUP and call 1G Link Level Policy, CDP enable policy, LLDP enable Policy
• Configure Switch Profile Policy and select Leaf 102 and port 1/10 over which external Switch is connected.

Create the Attachable Access Entity Profile named DCL-L2-AEP and associate Interface policy Group named DCL-L2-POLICY-GROUP and call 1G Link Level Policy, CDP enable policy, LLDP enable Policy after creating these.

• Click to Global Policies | Attachable Access Entity Profiles.
• Right-click on the Attachable Access Entity Profiles and then select Create Attachable Access Entity Profile
• Create Attachable Access Entity Profile named DCL-L2-AEP
• Click the NEXT button. In STEP 2 > Association to Interfaces, do not make any changes.

Associate Interface policy Group named DCL-L2-POLICY-GROUP and call 1G Link Level Policy, CDP enable policy, and LLDP enable Policy after creating these. In this we have already learned to create the above asked policies so we are not going to cover it end to end and here only screen shots are given.

Enable Policy create Interface Profile named DCL-L2-INTERFACE-PROFILE and associate above policy with it also Configure Switch Profile Policy and select Leaf 102 and port 1/10 over which external Switch is connected.
