To implement simplified interinstance
route sharing, your system must meet these minimum requirements:
JUNOS Release 8.2 or later for support on MX Series routing
platforms
JUNOS Release 5.4 or later for simplified interinstance
route sharing on M Series and T Series routers
Four Juniper Networks M Series, MX Series, or T Series
routers for the overlapping VPNs example: Two routers act as PE routers
and two act as customer edge (CE) routers
Six Juniper Networks M Series, MX Series, or T Series
routers for the nonforwarding instance example: Two act as PE routers
and four act as CE routers
