1. A computing system comprising:
a plurality of Distributed Unit (DU) servers each comprising a virtualized cell site router (vCSR) having a forwarding plane configured to perform Layer 2 (L2) switching,
wherein a first DU server of the plurality of DU servers is connected by a first physical link with a second DU server of the plurality of DU servers and is connected by a second physical link with an L2 switch, and
wherein the forwarding plane of the vCSR of the first DU server is configured to switch an L2 packet between the first physical link with the second DU server and the second physical link with the L2 switch.
