Receiving behavior Basic configuration of Layer 3 switch OSPF can let R3 learn 1.0/24 and 2.0/24 routes. Metric ? The protocol for RSTP BPDU is 2 and the version is 2 . Ip prefix-list 11 deny 12.12.12.0/24 ip prefix-list 11 permit 0.0.0.0/0 le 32 router bgp 100 The configuration on R3 is as follows: When ISP1 is down, the interface of GW connected to ISP1 is DOWN , and the traffic of PC access 100 is automatically switched to ISP2. Configuration and implementation The time interval between consecutively transmitted BPDUs of the root bridge . Default 2S Ip rip trigger RSTP is able to quickly transition between edge ports and point2piont links. The link type of the RSTP is automatically obtained through the duplex state of the interface. If the interface is half-duplex, the link type is the shared port . If it is full-duplex, it is point2point . Mechanism overview Designated port: Select a designated port on each segment , which will send the best BPDU on this segment . We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Ip dhcp snooping The current Ethernet implementation is such a service. Known via "ospf 1", distance 110, metric 20 VTP configuration So how do you perform an accurate calculation of the summary route ? Let's look at an example: Ip address 192.168.10.254 255.255.255.0 Go ahead and assign the interface of SW1 and SW2 to the PC to vlan10. The secure address entry can be configured by using the MAC ( SecureDynamic ) dynamically learned by the port , or by manually configuring the interface ( SecureConfigured ) and the sticy MAC address ( SecureSticky ). R3 and R4 update the routes in AS1 and AS2 to R5 and R6 at the same time . If R5 is required to go to AS1 ,ccnp route exam labs, take route R3 and go to AS2 . The next outgoing interface of the route is the port of the match . IP routing table Router ospf 3 Etc., then there is a prioritization between these methods: network>redistribute>aggregate Note that this principle is not used as a BGP routing routing policy. Compatibility Path attribute When deploying the campus network, we often have the following special requirements for switches: s suppressed routing entries, such as doing route summarization, suppressing details Therefore, from here we can see that the route summary is a risk of looping. One way to solve the above problem is to add a static route on the Layer 3 switch: ip route 192.168.0.0 255.255.0.0 null 0 , this way, when it receives access Note that the as-path access-list is also implicitly rejecting all by default. Set interface priority, CISCO IOS default 128 ; CatOS default 32 Straight connector Then the routing table of R2 is as follows: Metric value: The overhead of the router to reach the destination is an integer between 0 and 15 . The certificate contains the password information when it is verified using plain text. Paths: (2 available, best #1, table Default-IP-Routing-Table) Flag: 0x820 BGP neighbor relationship, the addresses are 3.3.3.3 , 4.4.4.4 , and 5.5.5.5 . The OSPF protocol runs in the AS , so that all routers can obtain the LOOPBACK network segment of other routers . On the R3 , BGP routes are advertised on the network segment 30.0 . R4 is the RR and R3 is the RR client . R5 will receive routing updates from 30 segments at the same time from R3 and R4 . How will it be routed? Which routing rule takes effect? First rule 8 does not apply because the two BGP routes NEXT_HOP are equal, both are 3.3.3.3 , not comparable (reaching 3.3.3.
