10.3.9.1Filtering 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-listcommand 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.

Command	Mode	Description
distribute-list ACCESS-LIST{in		Apply a specific access list or prefix list to incoming or
out} [INTERFACE]		outgoing RIP route updates on interface in order to
	Router	block the route.
distribute-list prefix PREFIX-		INTERFACE: interface name
LIST {in out} [INTERFACE]		ACCESS-LIST: access list name
		PREFIX-LIST: prefix list name

To remove the filtering access list or prefix-list to incoming or outgoing RIP route

Command	Mode	Description
no distribute-list ACCESS-LIST		Removes the application of a specific access list or
{in out} [INTERFACE]
	Router	prefix list to incoming or outgoing RIP route updates on
no distribute-list prefix PREFIX-
		interface in order to block the route.
LIST {in out} [INTERFACE]

10.3.9.2Disabling 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
		Disables the transmission of multicast RIP messages
passive-interface INTERFACE		on the interface.
	Router	INTERFACE: interface name
no passive-interface INTERFACE		Re-enables the transmission of RIP multicast mes-
		sages on the specified interface.

10.3.9.3Offset 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.
