R4#sh ip bgp Ip route 3.3.3.0 255.255.255.0 serial 0/1 Router bgp 64512 Revoked route Maximum-paths 2 Send Keepalive bag The address of the slave is the optimal next hop address. 15 //The effect is the same as above Name server PS : At present, the Ethernet frames we use are basically Ethernet II frames. (1) can learn the routing entries of R2 update, and the routing table is loaded with Sw(config)#vlan 100 Activate Port-Security (on the trunk interface) Difficult to resolve ...... Access-list 11 deny 192.168.1.0 This can indeed avoid the suboptimal path problem, but it leaves a hidden danger: Next Hop Note that there must be three layers between the DHCP server and the trunk interface. Because the unicast packet is relayed, the source address is the trunk interface configured with ip helper-address . Therefore, when the DHCP server returns the packet, the destination IP address of the packet. This is the interface IP of the interface configured with ip helper-address . Straight connector The configuration of R1 is as follows: The router goes to update the route of 3.0.0.0 Finally: R4#sh ip b Set ip next-hop verify-availability Therefore: the route is redistributed into OSPF , the automatically inherit these external routes BGP 's A_PATH property, note that only inherit AS_PATH !! wherein 2.2.2.2 is R2 of Router-ID , attention since 100.1.1.0 in R3 of OSPF RIP redistribute default route DHCP client broadcasts DHCP request Communicates with all other ports [Results] There is only 1.1.1.0 route in the routing table on R2 . BGP As a result, the priority becomes the highest 4bits , which is why the priority must be a multiple of 4096 ( 2 to the power of 12 = 4096 ). In addition, the system ID , the value of the VLAN ID , such as the spanning tree of vlan10 , the bridge ID of the switch is " 4bits priority + 10 + switch MAC" In a route-map statement, if there is no match statement, match all Switch(config)# vlan 20 Establish IBGP full interconnection and close the synchronization mechanism. This method is basically used at present. But this method has a flaw, that is, if IBGP After the TCP session is established, both neighbors must send an OPEN message. Both parties use the OPEN message to identify themselves and specify their own BGP running parameters. If the open message is accepted, a keepalive message is sent back for confirmation, and the update message can be sent after confirmation . The OPEN message contains the following: SW3 is small), so the interface connected to SW2 on SW4 wins and becomes RP . Other solutions, we will continue to introduce in the following experiments RIP and IGRP the passive-interface does not send routing updates, but to accept routing updates Lead ( PreambIe ) switchport trunk encapsulation dot1q switchport mode trunk The route closest to BGP NEXT_HOP is preferred , and the route is the route with the smallest IGP metric to the next hop router . * i100.0.2.0/24 There are 1.1.1.0 , 2.2.2.0 routes on R1 . Neighbor 4.4.4.4 ebgp-multihop 4 Configured MAC Addresses : 0 !! Manually configured secure MAC address, not here 10.1.23.2 1 : Request message, requesting all or part of the routing information from the neighbor; 20 access-list 1 deny 172.16.32.0 0.0.0.255 In fact, this is more a problem, because such an approach, in fact, the last 8 bit group no matter what, will be live match, he is even more imprecise. Static Routing Configuration For non-equivalent load balancing, see section 5.3. None Port Vlans allowed and active in management domain Fa0/20 1,10,20,30 *>i By default all routes belong to this community The default is shutdown , optional protect , restrict Off: EtherChannel not configured on interface RIP secondary address problem If the MED attribute of a route is lost, the default setting is to set the MED to 0. However, if this command is configured, if the route with no MED value is received , the MED of the route is set to the maximum value of 4294, 9672, 95. 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,ccnp switch dot1x lab, 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 . Next Hop R2(config-router)# distribute-list 1 in fa0/0 bootPC: 67 (client port number); bootPS : 68 (server port number) MTU? Refers to the second floor of the MTU , which is the interface MTU , refers does not contain a two-story frame header, Payload of MTU , the MTU value is generally not manually modify the default is 1500 bytes. Thus CISCO router supports Layer 2 data frame is a maximum value 1500 of payload plus the floor layer 2 frame header and the FCS : Objective MAC . 6 bytes + source MAC . 6 bytes + type field of 2 bytes + the FCS . 4 bytes So the total is 1518 bytes.
