For more detailed BGP state machine and neighbor relationship establishment process, please see the note document: " BGP State Machine and Neighbor Relationship Establishment Process" Access-list 1 permit any route-map PBR permit 10 match ip address 1 Next Hop RIP Version 2 Carrying Additional Information As an update source, send it to R3 . 100.100.100.0 [20/0] via 10.1.23.3, 00:02:57 Mismatch. This method requires that the community contains 100:11 and no-advertise to match. Know (configuration is only done on the RR ). Note that the RR only advertises or reflects the best path it knows. You can also configure DAI to discard the Ethernet frame source MAC and ARP body in the MAC illegal inconsistent ARP . This is followed by a further introduction. Local Network 12.12.12.0 mask 255.255.255.0 Manually modified. Ip mtu refers to the maximum value of the ip message. Compatibility 37 Defaut-network takes precedence and becomes the default gateway gateway of last resort . However, if the network specified by ip defaut-network is learned from a dynamic routing protocol, ip route 0/0 takes precedence. The set command above is used to define the detail route to be injected into the local BGP RIB . The injected prefix can be used EIGRP is run between R1 and R2 . At the same time, R1 and R2 announce their respective LOOPBACK interfaces in the EIGRP process. Neighbor 5.5.5.5 update-source Loopback0 If the BGP route is learned from other BGP peers , the MED does not carry the MED when it is advertised to the EBGP peer . Neighbor 10.1.35.5 unsuppress-map unsupp At this time, he himself will still forward if he receives the data packet to 3.0.0.0 , but will not forward to other rips. (Update source verification failed), on the other hand, R2 will not receive the 1.1.1.0 route from R1 , and then pass the same interface, with 11.1.123.2 Router bgp 200 Per packet load-sharing is disabled IP unicast RPF check is disabled Inbound access list is not set Outbound access list is not set If the MED of the received or generated route is empty , set the MED to 0 when advertising to the IBGP Peer . Switch B receives the TCN BPDU , sends a TCN ACK to confirm, and forwards the TCN BPDU to its own root port. RIP Version 2 MIB Extension When no BPDU is received for a period of time and the lifetime reaches MAX age , the bridge considers that the port is connected. 1000 If the number exceeds xx , disconnect the BGP connection with the neighbor and reconnect after 2 minutes. DAI configuration command Ip nat inside source route-map nat1 interface serial0/0 overload ip nat inside source route-map nat2 interface serial0/1 overload ip nat inside source route-map nat3 interface serial0/1 overload Experimental phenomena: Route-map test permit 10 ^10[012349]$ Retaining the NEXT_HOP attribute outside the federation within the federation ( 20s time), start to enter the listening state This attribute may not be supported. Unrecognized BGP processes ignore update messages containing this attribute and are not passed to other BGP neighbors. ! The next hop (the Next Hop) - if present , it identifies a better than advertised router address of the next hop address. In other words , the next hop address it noted , that in the same measure than - advertised subnet router closer to the destination. If this field is set to all 0s (0.0.0.0), the address of the advertising router is the optimal next hop address. Metric The thing we have to do is very simple. These subnets are continuous. It is enough to pick out the first two or three network numbers to calculate: Add configuration on SW2 : (global configuration mode) ip dhcp relay information trust-all s suppressed routing entries, such as doing route summarization, suppressing details S0 192.168.12.1/24 r1 Enabled by default, if an interface DOWN up, BGP answer immediately suspended. Each routing table entry must include at least the following three items: There are 2 forwarders (1 active) Troubleshooting 33 Network 192.168.254.0 0.0.0.255 area 1 General BGP routers do not accept containing its own AS routing information number, but can neighbor routing sources neighbors allowas-in a few of my as numbers , to make an exception. DHCP relay experiment Then the test lines will be powered up for detection. It is found that the 2nd and 3rd lines match, but the matching length of the 2nd line is the longest, so the final result: Network 12.12.12.0 mask 255.255.255.0 *Mar 1 00:11:47.951: ICMP: echo reply rcvd, src 2.2.2.2, dst 192.168.123.3 Fa0/22 1 !! vlan10 is trimmed 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 . Option82 If there are routes with the same prefix as follows (the default is sorted in reverse order of route acceptance order) EtherChannel Redis static route-map cisco END Strange phenomenon: In the BGP table of R5 ,ccnp 300 101 exam questions pdf, there are only two routes advertised by R2 , and the 100.0 route from R3 is not passed to R5 via R4 . In other words, we expect that AS345 will have redundancy to 100.0 network. Remaining path (through R1 , Routing entry for 192.168.1.0/24 Vlans allowed and active in management domain CAM and TCAM The adjacency list in the CEF component is used for MAC or Layer 2 rewrite information. We can affect the routing by setting the LP value. For example, the same implementation allows R4 to access 100.0.1.0 and go to R3 , accessing 100.0.2.0. Ip route 172.16.0.0 255.255.0.0 192.168.23.3 Arp spoofing solution Second column > Optimal path selected by BGP algorithm State is Listen ! RIP Version 2 Protocol Analysis ? In RSTP , topology changes are triggered only when a non-edge port transitions to the forwarding state. In other words, if a port loses its connection, it is no longer considered a topology change, which is different from 802.1D . 5.5.5.5 ^10[012349]$ BGP routing table entry for 11.11.11.0/24, version 2 Router ospf 1 Outline The result found can be understood as a pointer to find the associated outbound interface: Priority 120 (configured) 13 Ip sla monitor 1 CISCO Note: The DHCP option-82 feature is supported only when DHCP snooping is globally enabled and on the VLANs to which subscriber devices using this feature are assigned. If R1 turns on auto-summary and network 1.1.1.0 mask 255.255.255.0 , it is still updated to R2 with details. Route-map BGP2OSPF permit 20 match ip address 2 Unreliable based on broadcast Lab 3 : The access layer switch is inserted into option82 , and the upstream core switch also turns on dhcp snooping. If a path satisfies any of the following conditions, it is not a valid candidate in the optimal path selection process. 2 It is deployed on R1 and has an effect on these three routes. Then between R3 and R4 is the federal IBGP relationship, and between R4 and R5 is the federal EBGP relationship. 100 Router bgp 345 Activate the portfast feature for a specific interface We look at the above chart, two switches trunk both ends of the native vlan is not the same, what's the problem? First, the vlan2 communication at both ends is certainly no problem, but the communication between vlan3 and vlan4 has a problem . The data frame sent by the user of the left vlan3 goes out of the trunk from the left switch , and is not tagged, but these data frames are sent to the right switch. It will think that these data frames belong to vlan4 , which is a problem.
