The prefix list contains the serial number, matching from the smallest LLC. ( The Logical Link Control ) by the destination service access point DSAP ( Destination Service Access Point ), source service access point SSAP ( Source Service Access Point ) and This mechanism is very similar to CISCO 's BackboneFast feature. GLBP automatically manages the allocation of virtual MAC addresses and decides who is responsible for handling the forwarding work. These functions are performed by AVG ( active virtual i MED This feature is quite unstable and is not recommended. Ip sla monitor responder Fa0/20 Network, which is consistent with topology expectations, but the underlying cause is still due to the learning of R2 compared to IBGP routes from R3 . Offset-list 1 out 10000 fastEthernet 1/0 * i100.0.1.0/24 Detailed rules The next outgoing interface of the route is the port of the match . 159 220 , 91 70 Y If there are no dynamic and static routes on R2 , and the configuration is as follows: BGP introducing and transmission routes 1 Redistribute rip metric 10 subnets distribute-list 1 out rip access-list 1 deny 172.16.32.0 0.0.0.255 In fact, this is more a problem, because such an approach, in fact, the last 8 bit group no matter what, will be live match, he is even more imprecise. 2.2.2.2/32, version 55, epoch 0, per-destination sharing 0 packets, 0 bytes When an RSTP switch receives a BPDU with the TC bit set , it will: Router rip Set interface In the above figure, we inject OSPF routes into RIP . Traditionally, you can only set metrics on all incoming routes . However, with route-map , we can associate a defined one when configuring re-issue commands. A good route-map , in the route-map , we can create different properties or actions for different routes by creating multiple serial number statements. Vif PGM Multicast Host interface SwitchB first detects the topology change, and then generates the TCN BPDU and sends it out from the root port (because the root port is in the direction of the root bridge), B will continuously send the TCN BPDU until the designated switch C sends a TCN ACK to confirm. 100 Switching, and store the information in the cache, all subsequent data packets , you can not interrupt the system processor to perform queries and other operations , directly from ? Port-security configuration Router bgp 300 : 1 to 3 8.3.4 Questions 104 O E2 1.1.1.0 [110/20] via 10.1.23.2, 00:06:40, Serial0/0 SW3#sh int tru Configuration case s> 172.16.11.0/24 When a data frame is sent from the Access port, the switch strips the VLAN tag of the frame and then sends it out. Experimental verification There are 1.1.1.0 , 2.2.2.0 routes on R1 . neighbor RC-ip the EBGP Multihop- 2 // jump between them number 2 Weight S0 DCE *> 100.0.2.0/24 ? / / used to define the condition prefix to be injected The configuration of R5 is as follows: PVST+ Ip dhcp snooping information option allow-untrusted Once the ORF is deployed ,ccnp switch study guide pdf, the BGP peers will negotiate the ORF capability in the open message when the BGP peer relationship is established . If the negotiation succeeds, the ORF content is pushed using the route-refresh packet . It is valid only when the router (or Layer 3 switch) disables the routing function ( no ip routing ); // AS200 is the Primary AS and is used to configure the BGP process. The update is sent. At this time, both parties have their own routes, but 1.1.1.1 cannot ping with 2.2.2.2 . PVST+ If there is an error, enter the OpenConfirm state. Ip route 0.0.0.0 0.0.0.0 192.168.123.1 (Optional) Configuring the security address aging time Ip prefix-list ABC seq 5 permit 172.0.0.0/8 ge 24 As shown in the figure, R1 and R2 open the LOOPBACK interface with the addresses 1.1.1.1 and 2.2.2.2/24 respectively . Similarly, if ip route 3.3.3.0 255.255.255.0 null0 is the same. 10.1.12.2 Solution 1 , modify the default AD value of BGP so that its EBGP route AD value is greater than RIP to achieve the preferred purpose, but this solution may not be appropriate, because he will have an impression on all BGP routes, if only hope for 1.1.1.0 And 2.2.2.0 has an impact? Note that at this time, in the routing table of R2 , the 3.0 route is killed. Note that, 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.
