RIP Distribution Access Lists consist of rules that specify how a router distributes 
and/or accepts RIP routing information from other routers. Before sending an 
update, the router consults an Access List to determine if it should include specific 
routes in the update. When receiving an update, the router first checks a set of rules 
which apply to incoming updates to determine if it should insert those routes into 
its routing table. You can assign the rules per interface and per direction.
Up to 99 RIP Distribution Access Lists can be configured on X330WAN.
For example:

 To configure a RIP Distribution Access List number 10 permitting 

distribution/learning of network 10.10.0.0:
1

Enter the command: 

The default action of the Access List is “deny” and can be changed by the 

 command.

Whenever at least one permit rule exists, distributing/learning of all the 

remaining networks are denied, unless specifically permitted by another rule.

Apply the Distribution List created in step 1 by performing the following 
procedure within the 

 context:

— Enter the 

 command to apply list number 10 

created in step 1 on all updates received on all interfaces.

— Enter the 

command to 

apply Access List 10 on updates received on interface ‘FabricFastEthernet1’.

— Enter  the 

 command to apply Access List 10 to 

all advertised updates.

— Enter the 

 command to apply Access List 

10 to all advertised updates that were learned from OSPF (redistributed 
from OSPF into RIP).

If no Distribution Access List is defined, learning and/or advertising is allowed for 
all of the routing information. This is the default operation.
