To configure globally, use the command: SW3(config)# spanning-tree portfast bpduguard default , which activates bpduguard on all interfaces that activate the portfast feature : Spanning tree is used to solve this problem Neighbor 10.1.13.3 remote-as 345 2> Dynamic inbound soft reset EIGRP summary routing Match metric matches the route with the specified metric. match route-type matches the specified type of route match community matches the BGP community. EIGRP is run between R1 and R2 . At the same time, R1 and R2 announce their respective LOOPBACK interfaces in the EIGRP process. Route-map test permit 10 set community ? One thing to note here is that ip bgp-community new-format is used to convert the display format of community in CISCO IOS . When using regular expressions in the extended community-list list, the filtering results will vary depending on the format choice. ? TblVer InQ OutQ Up/Down State/PfxRcd BGP routing rules 1 BGP table on R6 : BGP , but the BGP routes ( BGP packets) between the BEs can be forwarded through the CD . For the CD ,ccnp route 300-101 ine, these BGP messages are regarded as normal IP packets and are directly forwarded and not viewed. RouterB routing 100.100.100.0/24 passed to A , NEXT_HOP is 10.1.123.2 ; EBGP non-equivalent load balancing RIP and OSPF re-release Neighbor 10.1.35.5 unsuppress-map unsupp Clear ip bgp * R3 R5 release B segment RIP routing, R2 and R3 can learn, at the moment we are in R2 and R3 are on to OSPF to inject RIP routing, assuming that R2 injected first, then the B route will be R1 update to R3 , R3 this When you learn B routing from both RIP and OSPF , then it will: / / Detailed release / / used to match summary routes Ip arp inspection validate { [dst-mac] [ip] [src-mac] } Redistribution will only perform re-release actions on routes in the routing table. Known via "bgp 200", distance 20, metric 0 Tag 13, type external IP protocol number 88 Route-map test per 10 Set as-path tag Once the ORF is deployed , 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 . The configuration is as follows: Weight If there is a tag , compare the VLAN tag of the frame with the PVID of the port . If the two are consistent, proceed to the next step; otherwise, discard the frame. Document number Match ip address prefix-list 11 set as-path prepend 600 CLUSTER_LIST is a string passed the route the route reflector cluster ( Cluster ) of the ID , the AS each route in the cluster has a reflection 32bit BGP is a classless routing protocol, a distance vector routing protocol, and automatic summarization is turned off by default (this depends on IOS ). 10.1.31.0/24 This subnet has been successfully updated " 10.1.31.0 " because it is the same as the main source of the R1 update source interface . Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale The next-hop attribute can be changed by next-hop-self Prefix-list PVLAN port type or ? ? Default route Transparent mode VTP configuration revision number is always 0 ? R1R2 establishes an IBGP neighbor relationship and maintains two BGP connections. The local interface is used to establish a neighbor relationship with the peer directly connected interface. Manually configure a secure address on the port-security interface. In R4 connected R2 interfaces capture found update package 11.11.11.0 attribute prefix is carried in the AS_PATH , content of AS 1 Ip dhcp pool BIND Content Addressable Memory Table content addressable memory Neighbor 5.5.5.5 update-source Loopback0 no auto-summary The DHCP server receives the DHCP message. If the server can identify option82 , it will assign an IP address to the client according to the information carried in option82 and select the corresponding policy. The server then responds with a DHCP packet, which also contains option82 information. Ip route 172.17.0.0 255.255.255.0 192.168.12.1 Sw(config-if)#switchport private-vlan host-association 100 202 As Primary the AS , 201 of Secondary the AS , R2 can be maintained in the original R1 of BGP case of updating the routing and connection is not affected, Origin attribute (priority order: IGP > EGP > Incomplete ) 15 [Experiment 6 ] There are subnet routes, the subnet route prefix length is different (matching and mismatching), and the matching route is taken. The next outgoing interface of the route is the port of the match . SW2(config-if)# glbp 1 10.1.1.254 192.168.67.6 Interface configuration: spanning-tree bpdufilter enable 10 ^10. Verification Experiment 2 Impact of CLUSTER_LIST in BGP Routing This feature is quite unstable and is not recommended. Routing? The key point is that R2 , through the R2 deployment redistributed routing , routing information may be selected in different transmission routes between the domains. Not advertised to any peer 200 Complete the basic interface IP configuration . Add the following configuration on R2 : Viewed as one logical link BGP neighbor neighbor to mean), BGP The network command, only the local routing loaded into BGP one way process. Network 100.0.2.0 mask 255.255.255.0 The so-called one-arm routing is on the Ethernet port of the router (must be above 100M interface) to carry VLAN traffic, let the router and switch run a trunk , use dot1Q encapsulation, at this time, in order to let the router's Ethernet port support Dot1Q To identify and carry VLAN traffic, you need to divide the subinterface of the physical interface, as shown in the figure above. Network Experimental verification ( EBGP equivalent load balancing) When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 Length of the suboption type Define the network segment associated with the address pool RIP Destination address: The address of the host or network. If a path satisfies any of the following conditions, it is not a valid candidate in the optimal path selection process. Neighbor maximum-prefix xx Weight Access-list 1 permit 192.168.2.0 The ip community-list is also like ACL . There are standard and extension points, 1-99 is the standard, and 100-199 is the extension. Extended community-list Fast switching may be called route-cache switching on some data. The KEEPALIVE message contains only 19 bytes of BGP headers, and does not contain any other data. None 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. In the initial situation, when R2 updates 192.168.12.0/24 route to R3 , we look at the attributes of the route prefix in the updata message: DLY=2560 , because the DLY of the R2 F0/0 interface is 100 microseconds. The unit in the message is 10us , so 10*256=2560 , this value is the value carried in the DLY field in the message . The value of the bandwidth is also similar. This can all be calculated, no problem.
