SD-WAN Service Side Config con BGP y subinterfaces

[wladmirmendozandc]

Hola, espero me puedan ayudar o al menos darme una idea

Tengo una CORE con dos Interfaces VLANs, Interfaces vlans 100 y interface vlan 101, y estoy implementando un nuevo router Cisco SDWAN.

Por petición del cliente quiere que la vlan 100, pertenezca a la VPN/VRF100 y la vlan 101 pertenezca a la VPN/VRF101.
Tengo un Trunk entre el SW Core y el cEdge. Los Gateways de la Vlans estan  en el SW Core mientras que en el cEdge hay sub Interfaces para Vlans 100 y 101 dentro del mismo dominio de direcciones.
Cada sub interface esta en la vrf 100 para vlan 100, vrf 101 para la vlan 101. El problema es que estoy aplicando BGP entre ambos equipos y parece no funcionar, y no se si me hace falta algo, he visto varios documentos y tutoriales pero nada parece funcionar. Si me pueden porfa ayudar. Les estoy dejando la configuracion y un diagrama porque lo estoy intendo hacer un LAB tambien.

@wladmirmendozandc 

 I have one question. You are using one interface on the cEdge side with subinterface.  Should not you to have one interface on the switch side in trunk to connect to the Router? 

[wladmirmendozandc]

Hiiii, you mean this config on my switch?

[Flavio Miranda]

Alright, this is it. I did not see this config above that´s why I asked.

 I believe you dont need this config on the cEdge "neighbor 172.168.100.1 ebgp-multihop 2 "

  If I understood properly, the router and the switch is directly connected.

[wladmirmendozandc]

hiiii

Yes, my cedge and the switch are directly connected, i delete "multiphop  line" in my config but it doesn't seem to work. It's the first time i configure BGP and VRF of this type.

[Flavio Miranda]

Is connectivity fine?

Did you run any debug?
