EFA- creating L3-vlan interface

MirajT — Wed, 09 Nov 2022 12:18:43 GMT

Hello Team,

I am new to Extreme; can anyone help to create L3-vlan interface using EFA.

I wanted to test vlan traffic coming from servers and not able to test its reaches to switch or not.

Regards,

Miraj

Miraj,

Thank you for bringing up this question. It is actually not as straight forward as creating a VE interface on your BL and assigning it an IP.

First I am assuming that you have already registered your SLX devices within EFA, Created a CLOS 3 Fabric, and have successfully configured your fabric; Fabric Status: configure-success

In this example I have a multihomed server connected to Leaf 1 and 2 via port 0/11:1, these devices then connect to the Border Leaf devices via the Spine.

Server <> Leaf1/2 > Spine > BLeaf

First we create the Shared Tenant for the connections were your VLAN traffic will enter the Fabric via Leaf 1/2:

efa tenant create --name <Tenant_Name> --type shared --vrf-count 0 --port <Leaf1_IP>[<Ports_i.e; 0/11:1-4>],<Leaf2_IP>[<Ports_i.e; 0/11:1-4>]

*I am using a range 0/11:1-4 here for scalability

Then we create the POs for the Southbound connections:

efa tenant po create --tenant <Shared_Tenant_Name> --name <PO_Name> --min-link-count 1 --speed 25Gbps --negotiation active --number 1 --lacp-timeout short --port <Leaf1_IP>[<Port_i.e; 0/11:1>],<Leaf2_IP>[<Port_i.e; 0/11:1>]

Then we create a Private Tenant for the Border Leaf devices:

efa tenant create --name <Private_Tenant-Name> --type private --vlan-range <Vlans_i.e; 101,102-104> --vrf-count <no_of_VRFs> --port <BLeaf1_IP>[<ports>],<BLeaf2_IP>[<ports>]

Next we create the VRF for the tenant:

efa tenant vrf create --tenant <Private_Tenant-Name> --name <VRF_Name> --routing-type centralized --centralized-router <BLeaf1_IP>,<BLeaf2_IP>

Then we create the EPG which will setup your L3 Interface:

efa tenant epg create --tenant <Private_Tenant-Name> --name <EPG_Name> --type extension --switchport-mode trunk-no-default-native --single-homed-bfd-session-type auto --po <PO_Name> --vrf <VRF_Name> --ctag-range <VLAN_Range> --anycast-ip <VLAN>:<Anycast_IP/CIDR> --local-ip <VLAN>,<BLeaf1_IP>:<Local_VE_IP/CIDR> --local-ip <VLAN>,<BLeaf2_IP>:<Local_VE_IP/CIDR>

I hope this helps!

Miraj,

I thought about this more this morning, and wanted to show another method in the event you only want to configure this on a single leaf switch:

First I create a Private tenant on the Leaf:

efa tenant create --name Tnt-101 --type private --vlan-range 101 --vrf-count 1 --port 10.x.x.41[0/10]

Then, create the PO:

efa tenant po create --tenant Tnt-101 --name po_101 --min-link-count 1 --speed 10Gbps --negotiation active --number 101 --lacp-timeout short --port 10.x.x.41[0/10]

Then, the VRF:

efa tenant vrf create --tenant Tnt-101 --name VR101 --routing-type distributed

And lastly the EPG:

efa tenant epg create --tenant Tnt-101 --name Epg-101 --type extension --switchport-mode trunk --po po_101 --vrf VR101 --ctag-range 101 --anycast-ip 101:10.10.10.254/24 --local-ip 101,10.x.x.41:10.10.10.1/24

Verification on Leaf:
