The cost value is increased, so that the OSPF metric of R4 going to 3.3.3.3 route becomes larger. What happens?

In this way, only the PBR action will be performed on the traffic entering the interface . The traffic originating from this device is invalid. Manual network through BGP , which originated from IGP , because BGP network must guarantee the network AS_PATH , LOCAL_PREF and MED , and added ORIGINATOR and CLUSTER_LIST for anti-ring. R3 , R4 , and R5 use OSPF to ensure inter- AS routing interworking, and use loopback to establish BGP neighbors.

Experiment 3 10.0.0.0/24 is subnetted, 1 subnets [Note] If the interface is passive , but at the same time the network interface in the routing process, the interface will not attempt to send updates or establish neighbor relationships, but the network segment where it is located will still be declared into the routing process. 200 201 300 switchport trunk encapsulation dot1q switchport mode trunk ?

Commands R4 has two BGP neighbors, where R3 is its federated IBGP neighbor and R5 is its federated EBGP neighbor. Command Summary Method three: default-information originate 2 : RIP-2 ; If the packets of the same data stream are sent in different paths, the IP packets may need to be re-queued when they reach the destination. This may reduce the forwarding performance of traffic such as VoIP , or if the packets arrive out of order, the quality of service will be degraded, packets may be discarded, and delay jitter will be added.

It is based entirely on other switching modes. The focus is on billing, monitoring, and network management of packets flowing through . Weight AS_Path 9.9.12.0 is directly connected, FastEthernet0/0 Then call the track object in the route-map Test purpose: VLAN information transfer RSTP has made minor modifications to BPDUs only on an 802.1D basis : FIG fancy, initial condition, C interface is elected non-designated port is Block , B sent from the designated port BPDU to C . Let us first consider the case of 802.1D . When the link between Root and B fails, since the interface connected to B on C is BLOCK , it does not send BPDU to B. Therefore, B considers itself to be Root at this moment , so it goes to C. Send yourself a BPDU for Root . Because at this time , the interface of C also stores the BPDU sent by B to the previous B , and this BPDU is compared with the BPDU sent by B to B.It is better, so C ignores these suboptimal BPDUs directly . Until the Max-Age timeout, the BPDUs sent by the previous B stored on the interface of C will be aged. At this time, the interface enters LST and starts to send BPDUs , indicating that the root is Root. . At this point, B accepts the facts and sets the interface that connects itself to C as the root port.
