BPDU operation Static Routing Configuration Floating Static Routes The route works, but it is basically not used now, because the uncertainty is too strong) Redirect time 600 sec, forwarder time-out 14400 sec Preemption disabled Not advertised to any peer Local ? STP uses four parts to solve the Layer 2 loop: R2 's F0/0 port is configured with proxy ARP , 3.3.3.0 network R2 itself is reachable, so R2 will respond to this ARP request with its own F0/0 port MAC . In fact, this is an ARP spoofing behavior: ) Next Hop Non-default (manually configured non-default) priority and cost unchanged Port-security configuration BGP basic configuration 0 , regarded as infinity Inject-map to use the route-map in Match ip address 1 Interface fast0/0 : Disabled This is the ICMP redirect message sent by R1 to R3 . Note that the Gateway address field in the header is filled with the next hop IP that is closer to the destination than the destination . The use of one-arm routing can solve the problem of data exchange between VLANs , but there are also various drawbacks, such as the interface of the router, the load is too large, and the traffic needs to enter and exit the interface or link twice, causing the load on the trunk link to be too heavy. And the scalability is particularly poor. Note that at this time, in the routing table of R2 , the 3.0 route is killed. Note that,ccnp tshoot simulation, in fact this time, Area within OSPF routers generated LSA has been loaded into the R2 of the OSPF Database alone rather than in R2 from the OSPF Database calculated route and prepares route entry is loaded into the routing table before, in the distribution direction play a role in the list, the 3.0 routes filtered out, so R2 routing table, there is no 3.0 the OSPF routing. However, although there is no 3.0 route in R2's own routing table , this does not prevent R2 from flooding the relevant LSA to R3 . Therefore, R3 still has 1.0 , 2.0 ,3.0 and 12.0 of the OSPF routing.
