Chapter 4 Operational Concepts and Configuration Examples

RIP Distribution Access Lists

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:
10.10.0.0 0.0.255.255
The default action of the Access List is "deny" and can be changed by the
ip distribution access-default-action
Note: Whenever at least one permit rule exists, distributing/learning of all the
remaining networks are denied, unless specifically permitted by another rule.
2 Apply the Distribution List created in step 1 by performing the following
procedure within the
— Enter the
created in step 1 on all updates received on all interfaces.
— Enter the
apply Access List 10 on updates received on interface 'FabricFastEthernet1'.
— Enter the
all advertised updates.
— Enter the
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.
