? Neighbor 10.1.13.3 route-map test out 200 i The upper digit is the individual/group bit. When its value is 0 , it can be considered that the address is actually the MAC address of the device . When its value is Iso-igrp metric mobile odr ospf rip Notifacation packets , resulting in session is interrupted; it can be re- AS on the border router IN strategic direction. RIP Version 2 Protocol Applicability Statement R1 In other words, R1 is not required to have a default route locally. IP Address Note the changes here: When R2 passes the route of 30.0 to R1 , the seconday AS number is no longer inserted . The ethernet , fast ethernet , and serial interfaces of the Cisco 1600 , 1700 , 2500 , and 2600 series routers use fast switching by default . 10.1.12.2 Exit HOLDTIME CISCO defaults to 180s ( 3 times KEEPLIVE timer ), which is included in the open message. Neighbor 1.1.1.1 weight 2000 sets the route sent by the neighbor to 2000 weight (local) At this time , the policy is used for R4 on R1 , and the route AS_PATH of 10.0 is inserted into the AS number of 100 100 , and R5 is preferably R3 . Why on R5 will select R3 , through experimental results, where R5 received two routes, one from the Federal EBGP neighbors, one from EBGP neighbors, the final preferred EBGP routing neighbors. Interface vlan 100 Each AS has an identification number ranging from 1 to 65535 , of which 64512 to 65535 are reserved for private use. Deception process ARP Response SW1(config-if)# glbp 1 10.1.1.254 Multi-hop EBGP If R1 turns off auto-summary and network 1.1.1.0 , the declaration is unsuccessful because there is no mask for class declaration. Timers Preferred routes sent by EBGP neighbors (relative to IBGP neighbors), preferred federation EBGP in federated EBGP and IBGP Although the decision to forward the message is implemented by the FIB , the second layer of frame rewriting is done according to the information in the adjacency list. The second layer needs to be rewritten to include the second layer for frame forwarding. head. For Ethernet, it is the new source, destination MAC , and type field. E.g: Known via "ospf 1", distance 110, metric 1 Length Ip address 10.1.13.1 255.255.255.0 ( FraIue check sequence ) R3 and R4 , R4 and R5 establish an IBGP neighbor relationship, and R3R4R5 uses LOOPBACK as the update source and refers to the neighbor . or: Bgp dampening half-life reuse limit limit limit maximum inhibition time SW3 immediately aging the BPDU stored on Fa0/3 , and port Fa0/3 enters the listening state and starts to send BPDUs. Re-routing interface connecting the local release, static routing weight is 32768 Paths: (2 available, best #2, table Default-IP-Routing-Table) Not advertised to any peer Used to advertise available routes, revoked routes, or both, Length : indicates the full length of the BGP packet, including the header. If R2 is added to the default route of R3 on the above basis, the data of the PC to the 10.1.13.0 network is still lost to R1 , which means that ip defaut-next-hop has higher priority than the default route. The following are five types of BGP packets and packet parsing: Length, or mask length. When paired with the above ACL , some students will even write Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . Regular updates, broadcast updates, routing table updates; according to rumors; distance vector routing protocols do not understand network topology We see that on R4 , there are redundant paths for the two networks of 100.0 , but they are not best . Naturally, R4 cannot use these routes. Why is it not best ? The reason is that the next hop, nexthop is unreachable. Therefore, the role of the no-prepend keyword is: Do not prepend local-as to updates from ebgp peers . If you advertise the route to the EBGP neighbor of the primary AS , the secondary AS number is not attached . Interface fast0/1 CDMA-Ix CDMA Ix interface Paths: (2 available, best # 2,ccnp r&s fee, table Default-IP-Routing-Table) Flag: 0x820 When ISP1 is down, the interface of GW connected to ISP1 is DOWN , and the traffic of PC access 100 is automatically switched to ISP2. Port ID neighbor 1.1.1.1 filter-list 1 weight xxx neighbor transmitted, and is filter-list 1 matching entry, weight is set to xxx Remote-ID suboption fields In the one local BGP routes advertised to EBGP the Peer time, whether they carry MED values , need to be determined under the following conditions ( not EBGP The port mac of the Layer 2 switch is used here :) To maintain a consistent BGP topology, the RR does not modify certain BGP path attributes when it reflects routes . These attributes include NH . Ip dhcp snooping vlan 10 Configure the primary VLAN to associate the Layer 2 secondary VLAN to the primary VLAN. Below is an example: R1(config-router)# network 12.12.12.0 mask 255.255.255.0 R1(config-router)# distribute-list prefix 11 out Gratuitous ARP , the free ARP is a special ARP Request/response message, that is, the Sender IP is the same as the Target IP (usually used for IP collision detection). 200 EGP The ARP packet of the element , then these messages correspond to an entry to save buffer usage. At the same time, only one system information will be generated. The AS_SEQUENCE attribute will be passed to R7 along with the route 11.11.11.0 , so the packet is captured on R7 . The attribute of AS_CONFED_SEQENCE is not visible in the route of 11.11.11.0 , so the external AS treats the federation as a single AS (outside I don't know the situation inside the federation) Tool overview 62 After the Port-Security feature of an interface is activated, the default maximum number of secure addresses is 1 , that is, the interface uses its dynamically learned MAC address as a secure address without manually configuring a secure address. This interface is equivalent to being exclusive to the MAC (the device to which it belongs). And the default violation is shutdown / / Start bgp dampening , the default is valid for all EBGP routes, you can also add route-map !! Globally enable DHCP snooping Due to the different port types, the switch processes the frames differently. The following is introduced according to different port types. Invalidation timer EIGRP , BGP and other dynamic routes learned. Ip address 10.1.34.4 255.255.255.0 Therefore than MED , 2 of MED small, 2 is the best path For example, if you go to a destination and there may be multiple equal-cost paths, you may actually use one of them when forwarding data. Use this command to see which interface is actually used for traffic forwarding. 10.1.13.3 Bgp confederation identifier 345 bgp confederation peers 64512 neighbor 4.4.4.4 remote-as 64512 R2(config)# router ospf 1 Ip dhcp relay information trusted Route tag: A tag that distinguishes between internal routing protocol routes and external routing protocol routes. Of course it includes information such as object MAC address , contents of the destination interface . In this case we need only one data stream (Flow) in the first packet do process BPDU later, when the operator device through STP after these interfaces will become the calculated root port, and the device immediately setting the interface root-inconsistent (blocked) state. Therefore, using this feature, it is possible to prevent the client device from becoming a root or to prevent these interfaces on the carrier device and connected to the client device from becoming root ports.
