SonicWALL TZ 190 Manuale Utente

RIPv2 Enabled (broadcast) - To send route advertisements using broadcasting (a single 
data packet to all nodes on the network). 

In the Advertise Default Route menu, select Never, or When WAN is up, or Always. 

Enable Advertise Static Routes if you have static routes configured on the SonicWALL 
security appliance, enable this feature to exclude them from Route Advertisement. 

Enable Advertise Remote VPN Networks if you want to advertise VPN networks. 

Enter a value in seconds between advertisements broadcasted over a network in the Route 
Change Damp Time (seconds) field. The default value is 30 seconds. A lower value 
corresponds with a higher volume of broadcast traffic over the network. The Route Change 
Damp Time (seconds) setting defines 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 temporary change in the VPN tunnel status.

Enter the number of advertisements that a deleted route broadcasts until it stops in the Deleted 
Route Advertisements (0-99) field. The default value is 1. 

Enter a value from 1 to 15 in the Route Metric (1-15) field. This is the number of times a packet 
touches a router from the source IP address to the destination IP address. 

If RIPv2 is selected from the Route Advertisements menu, you can enter a value for the route 
tag in the RIPv2 Route Tag (4 HEX Digits) field. This value is implementation-dependent and 
provides a mechanism for routers to classify the originators of RIPv2 advertisements. This field 
is optional. 

If you wan to enable RIPv2 authentication, select one of the following options from the RIPv2 
Authentication menu:

User defined - Enter 4 hex digits in the Authentication Type (4 hex digits) field. Enter 32 
hex digits in the Authentication Data (32 Hex Digits) field.

Cleartext Password - Enter a password in the Authentication Password (Max 16 Chars) 
field. A maximum of 16 characters can be used to define a password. 

MD5 Digest - Enter a numerical value from 0-255 in the Authentication Key-Id (0-255) field. 
Enter a 32 hex digit value for the Authentication Key (32 hex digits) field, or use the 
generated key.

Click OK.

SonicOS Enhanced provides Policy Based Routing (PBR) to provide more flexible and granular 
traffic handling capabilities.

A simple static routing entry specifies how to handle traffic that matches specific criteria, such 
as destination address, destination mask, gateway to forward traffic, the interface that gateway 
is located, and the route metric. This method of static routing satisfies most static requirements, 
but is limited to forwarding based only on destination addressing.

Policy Based Routing (PBR) allows you to create extended static routes to provide more flexible 
and granular traffic handling capabilities. SonicOS Enhanced PBR allows for matching based 
upon source address, source netmask, destination address, destination netmask, service, 
interface, and metric. This method of routing allows for full control of forwarding based upon a 
large number of user defined variables.
