•AllIPv6packetsingressingoregressingaC2portmustbesentoverthe

whenconfiguringmultipleC2portsforIPv6routing.

Preparing a Mixed Stack for IPv6 Proxy Routing
AtleasttwoC3switchesshouldbeaddedtoaC2stack,formanagementredundancy.
AsinanymixedC2/C3mixedstack,theC2firmware(release5.01orlater)mustbeinstalledonthe
