El ejemplo que dí yo es para una conexión entre routers, si lo que tienes es un 'router on a stick' puedes ver de armar una BDI entre las dos interfaces fisicas.
Hay un feature que puedes investigar, se llama IRB que haría que las dos interfaces del router se bridgeen y luego creas una interface logica como si fuese una SVI de un switch layer3.
Yo la verdad no lo recomiendo tanto, porque vas a depender de STP para mantener la estabilidad de esa implementación, pero puede llegar a ser la solución que buscas.

Hola Manuel,
De lado del router seria crear un puerto logico (Port-Channel) y asociar todas las interfaces fiisicas que gustes (hasta 8 del mismo tipo).

Si se llama Etherchannel, pero gestiona el protocolo LACP u 802.3ad
