A routing script is provided (routing-default.sh). If you have the following architecture:

    (Left) -- (R1) -- (trunks) -- (R2) -- (Right)

Packets from Left forwarded by R1 to trunks will be forwarded to R2 by trunks. Packets from Right forwarded by R2 to trunks will be forwarded to R1 by trunks.

For example, is R1 IP is 10.0.214.3 and R2 IP is 10.0.213.3, then you can use the following environment variables.

environment:
  ROUTING_SCRIPT: "routing-default.sh"
  ROUTING_GW_IP: "10.0.214.4"
  ROUTING_GW_NEXT_HOP: "10.0.214.3"
  ROUTING_ST_IP: "10.0.213.4"
  ROUTING_ST_NEXT_HOP: "10.0.213.3"
