Oi Allan,
Veja o exemplo abaixo.
Ele mostra como usar access-list com
ospf.
O ospf, como v�rios outros protocolos de roteamento
din�mico, pode anunciar
rotas aprendidas de outros protocolos, como por
exemplo do RIP.
Grato.
In Figure 1-2, there are no paths directly connecting the RIP clouds. However, in typical networks, these paths, or "back doors," frequently exist, allowing the potential for feedback loops. You can use access lists to determine the routes that are advertised and accepted by each router. For example, access list 11 in the configuration file for Router A allows OSPF to redistribute information learned from RIP only for networks 130.10.8.0 through 130.10.15.0: router ospf 109 redistribute rip subnet distribute-list 11 out rip access-list 11 permit 130.10.8.0 0.0.7.255 access-list 11 deny 0.0.0.0 255.255.255.255 These commands prevent Router A from advertising networks in other RIP domains onto the OSPF backbone, thereby preventing other boundary routers from using false information and forming a loop.
