Configuring a distribution access list example
About this task
For example, to configure RIP distribution access list number 10 permitting distribution and
learning of network 10.10.0.0, do the following:
Procedure
1. Enter the command: ip distribution access-list 10 1 permit
10.10.0.0 0.0.255.255
The default action of the access list is deny and can be changed using the ip
distribution access-default-action command.
Note:
Whenever at least one permit rule exists, distributing and learning of all the
remaining networks is denied, unless specifically permitted by another rule.
2. Apply the distribution access list created in Step 1 by performing the following
procedure within the Router RIP context:
a. Enter the distribution-list 10 in command to apply list number 10
created in Step 1 on all updates received on all interfaces.
b. Enter the distribution-list 10 in FastEthernet 10/3 command to
apply Access List 10 on updates received on interface ‘FastEthernet 10/3’.
c. Enter the distribution-list 10 out command to apply Access List 10
to all advertised updates.
d. Enter the distribution-list 10 out ospf command to apply Access
List 10 to all advertised updates that were learned from OSPF (redistributed
from OSPF into RIP).
Result
If no distribution access list is defined, learning and advertising is allowed for all of the routing
information. This is the default.
RIP limitations
Configuration of RIPv1 and RIPv2 is per IP interface. Configuration must be homogeneous on
all routers on each subnetwork. That is, RIPv1 and RIPv2 routers should not be configured on
the same subnetwork. However, you can configure different IP interfaces of the Branch
Gateway with different RIP versions. This configuration is valid as long as all routers on the
subnet are configured with the same version.
