Distribution lists
A distribution-list is used to control routing update either coming to your router or leaving from the router. Distribution-lists work on a variety of different IOS routing protocols like EIGRP, RIP, and OSPF. Distribution-list is one of the easiest ways to control routing updates, you can permit or deny routes using access-list or prefix-list or route map. Distribution-list can be applied to transmitted, received, or redistribute routing updates.
Each interface and routing process, Cisco IOS permits the following:
- One incoming global distribute list
- One outgoing global distribute list
- One incoming interface distribute list
- One outgoing interface distribute list
- One outgoing redistribution distribute list
