10.3.9.1 
Filtering Access List and Prefix List 
The hiD 6615 S323 switch is able to permit and deny conditions that you can use to filter 
inbound or outbound routes by access-list or prefix-list. Use the distribute-list command 
to apply the access list to routes received from or forwarded to a neighbor. 
User should configure the route information for a set of deny conditions based on match-
ing each access list or prefix list. In addition, this configuration is able to be applied on the 
specific interface as well as the whole routes information of switch.   
To block the route information based on matching access list or prefix list, use the follow-
ing command.

10.3.9.2 
Disabling the transmission to Interface 
To prevent other routers on a local network from learning about routes dynamically, you 
can keep routing update messages from being sent through a router interface. This fea-
ture applies to all IP-based routing protocols except for BGP. 
Disable the routing information to transmit on this interface of router, use the following 
command. 
Command Mode 
Description 
passive-interface
 INTERFACE 
Disables the transmission of multicast RIP messages 
on the interface. 
INTERFACE: interface name 
no passive-interface
 INTERFACE
Router 
Re-enables the transmission of RIP multicast mes-
sages on the specified interface. 
 
10.3.9.3 Offset 
List 
An offset list is the mechanism for increasing incoming and outgoing metrics to routes 
learned via RIP. You can limit the offset list with an access list.
