Select if you want to set the R-bit in router LSAs sent from this firewall to indicate that the firewall is not active. When in this state, the firewall participates in OSPFv3 but other routers do not send transit traffic. In this state, local traffic will still be forwarded to the firewall. This is useful while performing maintenance with a dual-homed network because traffic can be re-routed around the firewall while it can still be reached.
