CCNP Study Notes 4-route part-route control◆ Passive-interface-can be used in rip ospf. In rip, there are two network commands in the Process of ospf, which only receive and not send packets. In the process of ospf, there are two network commands: 1, advertise the route of the network address segment. The mask length is determined by the interface configuration, not the network. For example, network 10.0.0.1 0.0.255 declares the route of 10.0.0.1-254,

Advertise all loopback interfaces to the BGP process, except on R2, where the only loopback advertised should is LOOPBAC K 2. On R2, create a static summary route for the rest of it loopback interfaces nad advertise this static route in BGP. R4 should send a summary route to ITA representing all the R4 loopback interfaces. R4 should prefer the path to ITA networks
