VCStack and VRF-lite

Sharing VRF routing and double tagging on the same port

In this scenario, both VRF-lite traffic and double vlan tagged traffic is transported between the two x610 switches via a single shared port. The double tagging feature (nested vlans) makes use of the tag-in-tag technique. The inner tag comes from the end hosts whilst the outer tag is configured in the x610 switches. VRF-lite traffic remains separated from the double vlan tagged traffic.

Communication plan

Host 192.168.111.2 A can communicate with host 192.168.211.2 by VRF red routing.

Host 192.168.112.2 A can communicate with host 192.168.212.2 by VRF green routing.

Host 192.168.78.1 can communicate with host 192.168.78.2 by double tagging. When Ethernet frames enter the customer edge port, the switch adds an outer vlan tag (VID 20) on top of the customer inner vlan tag. Ethernet frames can also be sent untagged from the hosts. The customer VID (inner tag) is ignored whilst the frames are bridged between the two x610 switches. As Ethernet frames exit the customer edge port of the destination switch, the outer tag is removed. Therefore, when the packets exit the customer port, the original VLAN tags (or untagged Ethernet frames) are preserved.
