When track1 is true , that is, 10.1.1.2 is reachable, the data of the PC accessing the 100 network is lost to 10.1.1.2 . If track 1 is hung, the next next-hop is switched. Federal related features: Redistribute ospf 3 subnets route-map OSPF3to1 router ospf 2 It is recognized that the attributes must be followed, and the source of routing updates is clarified. If the ibgp keyword is not associated , only EBGP routes will be equivalently load balanced (by default only for EBGP routes). If maximum-paths is not configured , the next routing principle will be followed. Ip address 100.0.2.1 255.255.255.0 If RP2 matching route exists in the BGP table, RP2 is advertised ; if RP2 hangs, RP1 is advertised. ! Due to the lack of a feedback mechanism, the interface connecting A to Root from Listening to Forwarding needs to experience a delay of 15*2s . In this case A , B , C the second line on the user traffic problems (since D in better received BPDU after the P1 port block , this time ABC corresponds A root port transitions to the forwarding are in the network before the " buffer zones " ) AS_SET : A list of unordered AS numbers on a path to a particular destination The MAC address is burned in the ROM of the Network Interface Controller (NIC ) . So to rule 12 : if multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred . Ip dhcp pool vlan10 network 192.168.10.0 /24 30.30.44.45 /24 *> 1.1.1.1/32 10.1.23.2 65 0 12 i EBGP neighbors must be directly connected to establish an EBGP session. but Based on UDP protocol ports 67 and 68 Re-routing release ( Redistributing Routing Protocols ) Access-list 2 permit 10.1.2.0 route-map cisco permit 10 Catos port switch ID in the default priority 32 (priority . 6 th 'bit ) , the IOS switch default 128 (priority field . 8 bits) Route matching tool Modified OSPF the AD value Port-Security Overview Two routes, on R2 we introduce these two routes using re-release : Set interface priority, CISCO IOS default 128 ; CatOS default 32 Active is 10.1.1.252 (primary), weighting 100 (expires in 7.028 sec) Arp replies sent: 1 / / Use this command to delete The configuration of R2 is as follows: After the maximum number of allowed MAC addresses of the port-security interface is set , the security address entries associated with the interface can be obtained as follows: We found that both O , O IA or with the FA 's OE2 routes are redistributed into BGP later, these BGP routes Next-hop are they in OSPF the IGP next hop. At the same time, the network segment where the OSPF direct connection port is activated locally will also be injected into BGP . After the injection, Next_Hop is the router (BGP update source IP) . Revision date Ip dhcp snooping trust SW1(config-if)# switchport trunk allowed vlan ? Show pvlan mapping Violation Mode : Shutdown !! After the violation, the default is shutdown Aging Time : 0 mins 172.16.10.1 , in fact, this IP may be understood as 172.16.0.0/16 within the network, but also in 172.16.10.0/24 within the network, of course,ccnp switch portable command guide, here we can see it, then who is more accurate? It is clear that 172.16.10.0/24 is more accurate, we say that its matching length is longer than 172.16.0.0 . 2 : Clear text verification; [Experiment 6 ] There are subnet routes, the subnet route prefix length is different (matching and mismatching), and the matching route is taken. Show run int | include bia can see all the MAC , the first MAC will be used by the spanning tree, which is the CPU 's MAC . Next is the MAC of each Ethernet interface . This port type defined by RSTP is very similar to Portfast . Because these interfaces are used to connect to the host, loops are generally not generated. These ports can skip the LST or LRN to directly transition to the forwarding state. And when these interfaces are up , they will not cause topology changes. In addition, once the edge port receives the BPDU , it immediately loses the feature of the edge port and becomes a normal spanning-tree interface.
