Global-Inbound
The global-inbound attach point for RIP allows you to filter or update inbound RIP routes that match a route
policy.
The following example shows how to filter the inbound RIP routes that match the route policy named rip-in:
router rip

The global-outbound attach point for RIP allows you to filter or update outbound RIP routes that match a
route-policy.
The following example shows how to filter the outbound RIP routes that match the route policy named rip-out:
router rip
Interface-Inbound
The interface-inbound attach point allows you to filter or update inbound RIP routes that match a route policy
for a specific interface.
The following example shows how to filter inbound RIP routes that match the route policy for interface
0/1/0/1:
router rip
Interface-Outbound
The interface-outbound attach point allows you to filter or update outbound RIP routes that match a route
policy for a specific interface.
The following example shows how to filter outbound RIP routes that match the route policy for interface
0/2/0/1:

Attached Policy Modification

Policies that are in use do, on occasion, need to be modified. In the traditional configuration model, a policy
modification would be done by completely removing the policy and re-entering it. However, this model allows
for a window of time in which no policy is attached and default actions to be used, which is an opportunity
for inconsistencies to exist. To close this window of opportunity, you can modify a policy in use at an attach
point by respecifying it, which allows for policies that are in use to be changed, without having a window of
time in which no policy is applied at the given attach point.
