LAN Route Advertisement
Note: This feature is only available on the PRO 100, PRO 200, PRO 230, PRO 300, and PRO 330.
The SonicWALL uses RIPv1 or RIPv2 to advertise its static and dynamic routes to other routers on
the network. Changes in the status of VPN tunnels between the SonicWALL and remote VPN
gateways are also reflected in the RIPv2 advertisements. Choose between RIPv1 or RIPv2 based on
your router’s capabilities or configuration. RIPv1 is an earlier version of the protocol that has fewer
features, and it also sends packets via broadcast instead of multicast. RIPv2 packets are
backwards-compatible and can be accepted by some RIPv1 implementations that provide an option
of listening for multicast packets. The RIPv2 Enabled (broadcast) selection broadcasts packets
instead of multicasting packets is for heterogeneous networks with a mixture of RIPv1 and RIPv2
routers.
Tip There is no route advertisement on the WAN.
To enable Route Advertisement on the LAN, select one of the following types of RIP Advertisements:
•
RIPv1 Enabled - RIPv1 is the first version of Routing Information Protocol.
•
RIPv2 Enabled (multicast) - to send route advertisements using multicasting (a single data
packet to specific notes on the network).
•
RIPv2 Enabled (broadcast) - to send route advertisements using broadcasting (a single data
packet to all nodes on the network).
Multicast destination IP address - sends the packet to a specific group of nodes on the network
listening for the RIPv2 multicast address of 224.0.0.9.
Broadcast destination IP address - sends packets to all nodes on the network.
•
Advertise Static Routes - If you have static routes configured on the SonicWALL, enable this fea-
ture to exclude them from Route Advertisement.
•
Route Change Damp Time (seconds) - is the delay between the time a VPN tunnel changes state
(up or down) and the time the change is advertised with RIP. The delay, in seconds, prevents
ambiguous route advertisements sent as a result of a temporary change in a VPN tunnel status.
Enter a value in seconds between advertisements broadcasted over the network in the Route
