BGP-EVPN over MPLS (Cisco IOS XE)

[ArturMelyan80360]

Hello folks,

I need to configure bgp-evpn over mpls between 2 PEs. 

Actually, it is hub and spoke topology with 2 hubs. 

At the spoke side the client is attached to vlan(Ethernet Segment). Under interface vlan I am using the following commands:

no ip address
service instance 44 ethernet
encapsulation dot1q 44

And here is the EVPN configuration:

l2vpn evpn
replication-type ingress
router-id Loopback100
l2vpn evpn instance 44 vlan-based

BGP configured with address-family l2vpn evpn. BGP session is being established. 

Configuration for bridge domain is the following:

member Vlan44 service-instance 44
member evpn-instance 44

At the hub side the configurations are the same, only difference the ES is port-channel with different service instances. 

In case of VPLS using xconnect command at the spoke side and l2vpn vfi context command at the hub side everything works just fine. But with evpn the mac and ip addresses  aren't seen in show commands output.

Any advises or references to appropriate topics would be greatly appreciated.

Thank you in advance.

Hi @ArturMelyan80360 ,

Applying the following commands under the VLAN interface will not work. They need to be applied on the physical interface.

service instance 44 ethernet
encapsulation dot1q 44

Hello @Harold Ritter ,

Thanks for your answer.

This command doesn't exist under physical L2 interface. 

I have cisco isr 1111 router with 8 l2 and 2 l3 interfaces. 

L3 interfaces have already used with connection to ISP. 

Is there another way to configure EVPN on this router?

The IOS XE version is 17.3.4a.

At the hub side it is cisco isr 4351.

Hi @ArturMelyan80360 ,

Thanks for the additional platform and release information. I quickly checked with the Cisco Feature Navigator and could not find EVPN as a supported feature on neither the ISR4351 nor ISR1111. You can check with your account team to see if it is on the roadmap.

Dear Harold,

Appreciate your answer.

I just choose to believe this list of features on feature navigation site is not really a complete list.

Otherwise, why the commands related to l2vpn evpn exist at all?  

And here is the full list of options of this command:

ISR1111(config)#l2vpn evpn ?
   ethernet-segment Ethernet segment
   instance EVPN instance (EVI)
   logging Configure logging flags

Anyway, if this is true, then the only way to achieve this scenario it is to utilize SD-WAN feature with vxlan encapsulation?
