Unrecognized BGP processes ignore update messages containing this attribute and are not passed to other BGP neighbors. Access-list 1 permit 10.1.1.0 Timeout Configure abort timeout interval It can only be mapped to the ethernet of vlan 2 In Ethernet, the value of CFI is 0 . Bridge ID Match ip address prefix-list 1 2 Network without mask is a class declaration, plus the mask is no class declaration After Port-Security is enabled, related parameters have default configuration. The BGP configuration of R2 is as follows: Solution 3 , so the above question is, R2 should not be to its EBGP announcement neighbor 1.1.1.0 , therefore CISCO support the use of command: Network Then let's go to R4 and see: Neighbor 1.1.23.2 send-community Match ad , abcd , aaabcd, etc. Then, in order for R3 to dynamically learn the routing of production and office servers, it is now necessary to redistribute these two static routes into OSPF . Of course,ccnp tshoot pdf, there are tricks when re-publishing. ACL Ip nat inside source route-map nat4 interface serial0/0 overload 0 7 15 31 BGP routing table entry for 100.100.100.0/24, version 2 Paths: (2 available, best #2, table Default-IP-Routing-Table) Flag: 0x820 Run RIPv2 , the default R1 update 1.0.0.0/8 is summarized to R2 , and the automatic summary is closed on R1 , then R2 learns to 1.1.1.0/24 , and since it still starts automatic summarization, the update to R3 is 1.0.0.0. /8 . This time if R2 on ip route 1.1.1.0 255.255.255.0 null0 , then R2 is routed on the table 1.1.1.0 becomes static static routing, and the R2 is no longer to R3 updated RIP 's Version Timers 29 Match ip add pre 1 Dhcp-bindings permit —Logs DHCP-binding permitted packets. Advance Method two: neighbor xxx default-originate 0 00:11:53 If multiple next hop IPs are defined , when the local outbound interface associated with the first next hop is DOWN , it automatically switches to the next next-hop . Penalize mode shutdown (enter err-disable state) while sending an SNMP trap OSPF . In this way, for R4 , it goes to 192.168.1.0 , there is a sub-optimal path , that is, around the long way, take R2-R3-R3-R5 Optional attribute to sum up Weight Experiment 1: host-dependent AS No. 16bit local AS Number CFI 0 ? Below is an example: Origin IGP, metric 0, localpref 100, valid, external, atomic-aggregate , best AS_CONFED_SEQUENCE A list of ordered AS numbers on a path to a particular destination. Update it; however, it does not send its secondary address 11.0.0.0 segment from fast0/0 to R1 (unless the split horizon is turned off). Ip route-cache flow show ip cache flow Run RIP between R1 , R2 , and R3 , and R1 and R2 are injected into their respective loopback ports. ? Longest match principle 10 * i100.0.1.0/24 2> Dynamic inbound soft reset Sign ^10. For details on the BGP neighbor table field, see the show section of the BGP Configuration section of this document. mark If the prefix does not match any entry in the prefix list, it will be rejected When a BGP route is sent from the group members of the cluster to the RR , RR If the local end has this feature enabled, the next-hop device does not support CDP , then switch to the next next-hop . If there is no next-hop , skip the PBR. 5.5.5.5 Because when actually deployed, SVI mouth may be more, go to if one of the no passive-interface to configure the amount may be relatively large, so you can choose to passive-interface defaut all interfaces of all passive off, and then a single interface to no passive -interface . When the DAI discards an ARP packet, the switch stores a message in the log buffer , and then generates a system message system information. After the system information is generated, the switch clears the previously stored entries from the log buffer . Each entry contains information such as VLAN , port number, source destination IP address, and source destination MAC address . The third column is empty or i . If it is empty, the route is obtained from the EBGP neighbor. The i indicates that this is the route learned from IBGP . The last column indicates the origin of the BGP routing information. //The details are not released. Use a static route to the next hop An escape character that is used to convert the control character immediately following it to a normal character Community Y Second column > Optimal path selected by BGP algorithm Interface f0/3 Encapsulation protocol Ip arp inspection vlan 100 logging acl-match none Statically configure a dhcp snooping bingding dabase entry. The command is configured in privileged mode. Track 1 rtr 1 reachability 1,20,30 Set local-preference 300 None does not send updates ( passive ) Ip dhcp relay information trust-all At the same time, the same OSPF route is learned from both processes and is used on a first come, first served basis. Therefore, if R3 first learns the route from R1 , it will naturally ignore the one that R2 re-releases. However, if the neighbor relationship between R1 and R3 is already obtained in R3 Ip next-hop recursive After the above configuration is implemented, R1 will filter out the 3.0 route. Passive-interface 50 Router ospf 1 Commands Route-map 8 There can only be one Isolate vlan in a primary VLAN.

Port number 520 Private-vlan community Vlan 102 The main routing table version is injected into the last table version in the main routing table. If the routes are from EBGP neighbors, it is preferred that the oldest EBGP neighbor came routing, reduce the impact of the roll (this provision mainly EBGP Routing Information Protocol (RIP) When using Ip default-network to refer to a network locally, if the network number exists in the routing table, the router will designate the network as the default gateway. 200 i 192.168.2.0/24 BGP table version is 1, main routing table version 1 As shown above, the position of the line is 16+4=20 , so we get the summary address: 192.168.0.0/20 , which is the most accurate summary address. Route-map RP permit 10 match policy-list as100 Configure ARP packet rate limit neighbor to mean), BGP The network command, only the local routing loaded into BGP one way process. Local updater ID is 0.0.0.0 (no valid interface found) 200 i 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 . Path ISL The boundary will change, so if you make an AS_PATH modification policy for IBGP neighbors , it will be nonsense. *>i100.0.2.0/24 For a class B address, the default subnet mask length for a class B address is 16 bits, so 172.16.0.0/16 itself is a primary class network number. As another example of a through, 10.1.12.0/24 , first 10 beginning, which is an A class address, A Class mask default address is 255.0.0.0 , so 10.1.12.0/24 its major network number is 10.0 .0.0/24 . 100 Can be configured in global mode or in interface mode, the difference is as follows: global configuration: spanning-tree portfast bpdufilter default 10.2.12.1 from 10.2.12.1 (1.1.1.1) A support DHCP Snooping switch, if it untrust interface, received from the downstream transmission of the switch, and with option82 the DHCP message, the default action is to discard these packets. If the switch is turned on the DHCP Snooping and with option82 the DHCP message is trusted received on the interface, the switch will receive these messages, but does not create a message based on information contained in the DHCP bingding databse entries.
