U Poisoned reverse
Poisoned reverse prevents routing loops from forming. An update is sent
back to the router that propagated the route to inform it that the network is
unreachable at the associated interface.
However, this has a significant disadvantage over WAN connections: The
central location transmits a high number of routes which would then suffer
from route poisoning, so leading to a heavy load on the available bandwidth.
For this reason, poisoned reverse can be manually activated for every LAN/
WAN interface.
The LAN and WAN RIP tables have been extended for the configuration of
poisoned reverse.
D Poisoned reverse
The use of poisoned reverse can be set here.
D Possible values: Yes/No
D Default: No
U Static routes for constant propagation
Routers use RIP to propagate not only dynamic routes but statically config-
ured routes as well. Some of these static routes may not be constantly avail-
able, for example when an Internet connection or dial-up access is
temporarily unavailable.
For a static route, the setting for "Active" in the routing table defines whether
it should be propagated constantly or only when it is actually reachable.
WEBconfig: Setup
 IP router  IP routing table
D Active
Indicates the route's status.
D Possible values:
Yes: Route is active and propagated constantly.
No: Route is inactive and is not propagated.
Semi: Route is active and is only propagated when it is reachable.
D Default: Yes
U Extended filter options
Until now routes learned from RIP could only be filtered by their routing tag.
However, it is desirable to be able to filter routes by their network address as
well. For example, "only learn routes within the network 192.168.0.0/
255.255.0.0".
