switchport trunk encapsulation dot1q switchport mode trunk Switch(config-if)# switchport mode encapsulation {dot1q | ISL} When the network topology changes,ccnp tshoot 300-135 cbt nuggets kickass, the switch that first recognizes the change will send a TCN BPDU . The switch sends a TCN when the following times occur : Message Type 3.3.3.3 10.1.13.3 Metric problems 44 The BGP configuration of R4 is as follows: s> 172.16.10.0/24 Ip policy route-map PBR View and verify: Retaining the NEXT_HOP attribute outside the federation within the federation BGP must be identifiable, update messages can include aggregate-address 192.168.0.0 255.255.0.0 as-set after, R1 can only learn to 2.0 , the summary route are rejected, the reason is 1.0 carries no-adver of Community Community , when the summary route plus the as-set keyword after Will inherit its community , so the summary route also carries no-adver , this time 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 BGP router identifier 10.1.13.3, local AS number 345 Distribute-list Sw1(config-if-range)#no switchport // Configure the L3 interface / / Configure etherchannel , ID is 1 , the mode is desirable Neighbor 10.1.12.1 dmzlink-bw Two-point bidirectional routing re-release implementation 98 10.10.10.0/24 In the port field of the circuit-ID suboption, the port numbers start at 3. That is to say, in this field, the port number is from 3 , the first port number is 3 , and so on. For example, a 24- port switch with an SFP slot , port3 is fast x/0/1 , port4 is fast x/0/2 , and so on, port 27 is the x/0/1 port of the sfq module . Where x is the stack member number. ? Ip dhcp snooping vlan 10 In R6 connecting the R4 interface to capture found update package 11.11.11.0 prefix attribute carried AS_PATH contains 2 th content: 200 i Of course, on R3 , the same effect can be achieved with the distribution list in the in direction. If deterministic-med is turned on, the information of the route prefix is regrouped by AS. R1(config-router)#distribute-list 1 out ? RIP and IGRP the passive-interface does not send routing updates, but to accept routing updates VLAN 15 bits with the current 10 th, then the support up to 2 of the 10 power = 1024 th VLAN BGP decision Redis ospf 1 route-map test R1 announces 1.1.1.0 into BGP , and R2 learns these two routes from 10.1.12.1 and 10.2.12.1 respectively. When the link between R1 and R3 fails, the same network will still have problems. Because R2 re-releases the locally configured static summary route into the If R1 turns off auto-summary and network 1.1.1.0 , the declaration is unsuccessful because there is no mask for class declaration. ! It means for VLAN100 traffic, not to log the ARP ACL discarded packets match STP cost to the root bridge 345 The above command creates a policy-list ; the Policy-list can only contain a match statement. Paths: (1 available, best #1, table Default-IP-Routing-Table) Flag: 0x820 Transmit limit accumulator 0x0 (0x0) IP MTU 1500 Interface R4#sh ip bgp Range character example: Ip dhcp relay information trust-all 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 . R1 , R2 , and R6 advertise the routes of their respective ASs through EBGP . In AS345 , these routes are re-advertised into OSPF , and then advertised back to BGP on the other two routers , and then advertised to their EBGP peers . . Match ad , abcd , aaabcd, etc. MTU is the largest transmission unit, and different systems have different settings and understandings for MTU . When port-security mac-address sticky is activated on the interface , then: BGP routing table entry for 11.11.11.0/24, version 5 ^a.$ WORD Hash When track1 is true , that is, 10.1.1.2 is reachable, the data of the PC accessing the 100 network is lost to 10.1.1.2 . If track 1 is hung, the next next-hop is switched. Command summary 81 Using this feature may reduce the performance of the device to a certain extent. In addition, you must ensure that CDP is enabled for both the neighbor and the router interface . Process switching and CEF support this feature, but dCEF does not. basic configuration If R1 turns on auto-summary and network 1.1.1.0 , the announcement is unsuccessful. 1,10,20,30 Set local-preference set weight 100.0.1.0 the BGP route, preferably up to R5 . Trunking Community Aggregator Ip prefix-list 11 deny 12.12.12.0/24 ip prefix-list 11 permit 0.0.0.0/0 le 32 router bgp 100 Once the portfast port is connected to the device, the interface can bypass the listening and learning states and enter the forwarding state directly . None AFI (Address family identifier) The default is 10 , this default value is generally sufficient. If the route is marked d , it means that the route is suppressed. If it is h , it means that the route has signs of flipping. / / Interface or protocol Match, and the result is that there is no match, it is directly discarded, regardless of whether there is a valid entry in the DHCP Snooping database . This has already been said before. Address-family ipv4 unicast Switch(config)# ip default-gateway 192.168.255.254 !! Set the gateway for the access switch itself Cisco CEF is the most efficient three-layer protocol. CEF uses a hardware-based platform . It not only stores data in the system buffer, but also " prestores " the entire routing table, topology table , and all next hop addresses and MAC addresses , as long as the routing table, The entries in the topology table , regardless of whether there is a data request sent to its destination address , will be pre-read in advance , pre-set the cache . Thus , when there is a new data request to send , the CPU is not required to query the destination interface , destination MAC Address and other information , but read directly from the cache , so the forwarding speed is greatly improved .
