   XRO: (AB1, B1, B2, BC1, C1, C2)

Notes
-----
The figure incorrectly shows the XRO to include the Egress as well. 

The text in the RFC is correct - "....so the ERO and XRO signaled at Ingress could be (A3-strict, A4-strict, AB2-strict, Egress-loose) and (AB1, B1, B2, BC1, C1, C2), respectively. " 

The editorial error exist in the figure.
