201 Spanning Tree Protocol Neighbor 3.3.3.3 update-source Loopback0 neighbor 5.5.5.5 remote-as 64513 Snooping can protect against DHCP spoofing. On the other hand, it will get DHCP snooping binding on the switch. Weight [Experiment 1 ] The following are several situations. Switched network management // is equivalent to route-map not matching ( permit ) any entry, so all details are released The prefix list contains the serial number, matching from the smallest Port-security supports private vlan Router(config) router rip Bgp-policy accounting input Four types of AS_PATH path attributes Holddown timers are ignored in some versions of IOS , that is, they do not take effect even if they are set. A strange phenomenon has appeared. It seems that R4 does not reflect the route from R5 to R3 . Why? In theory, the RR will learn from non- client of IBGP neighbor to route reflection to their Client , but it is clear,udemy ccnp tshoot, in this experiment, R4 and did not learn from R5 route reflection to their Client . R1(config-router)# redistribute connected subnets BGP 802.1q Note that PEs in an MPLS VPN environment do not have this limitation. This route was therefore sent to R1 . Local Connectionless packet transfer service At this point, the direct connection is re-released on R2 , and it is found that 1.1.1.0 has not been re-released into RIP. Interface loopback2 802.1Q support 4096 Ge VLAN Experimental topology and description 1 Weight BPDU , then he will send again. Therefore, for 802.1D , the root bridge will send BPDUs to all interfaces continuously . The non-root bridge will receive BPDUs from its own root port and send BPDUs to its designated port . Non-designated ports will not send. BPDU 's will only listen. When the routing policy changes, the neighbor is requested to re-advertise the route ( BGP does not periodically send updates) Ip prefix-list ABC seq 5 permit 172.0.0.0/8 (Of course, in the case of FA=0.0.0.0 ), then, in this figure, if the cost of R2 to ASBR-R3 is smaller, the final R2 will be preferred. Etherchannel port does not support pvlan We look at the above picture, the external detail route 172.16.32.0 – 39.0/24 , and the summary route 32.0/21 are introduced into OSPF by R1 , now Show ip bgp injected-path to display Aggregate-address summary address as-set advertise-map BGP , but the BGP routes ( BGP packets) between the BEs can be forwarded through the CD . For the CD , these BGP messages are regarded as normal IP packets and are directly forwarded and not viewed. Neighbor 10.1.12.1 capability orf prefix-list send neighbor 10.1.12.1 prefix-list FILTER in RC and RA are separated by RB . In this case, EBGP runs through a non- BGP router by using the configurable " multi-hop EBGP" feature . In other words, RB can not support BGP , and the configuration is as follows ( RA ) Path not synced, but sync is on *> 11.11.11.0/24 1 Select interface mode according to specific protocol Configure the interface: Through AS_PATH affect route choice 14 Switch(config)# vlan 255 Switch(config)# interface fast0/15 Switch(config-if)# switchport mode trunk Switch(config)# interface vlan 10 DTP Run the switchport port-security mac-address command to configure a static security address entry. After the route-map is called, the matching action will be executed from the smallest sequence number. If the conditions in the sequence number are matched, the set command is executed . If the conditions do not match, the switch to the next sequence number is continued. Match the action. Timer bgp 0 0 neighbor never goes down The RID is the largest IP address on the router and tends to be assigned to the loopback address. It can also be set manually by the bgp router-id command. If a path contains an RR attribute, the route generator ID ( originator ) will replace the RID in the optimal path selection process. Dot1q R4#sh ip b 100.0.1.0 Beta Recognized Switchport access vlan 100 interface fast0/24 R5 will receive BGP routes for the 10.0 network from R4 and R3 at the same time . R5 will first prefer R3 because the route that R4 passes to R5 keeps NEXT_HOP and is still R1 . Therefore , the next hop of this route from R4 on R5 . Unreachable, R5 is preferred to R4 by modifying the next hop to itself after R4 modification . Network LocPrf Neighbor 1.1.23.3 distribute-list 1 out Then first mark the route prefix of 30.30.30.0/24 on R2 , use the community tag, and configure a route-map at the same time. For example, if a route is flipped, the penalty value is 1000. In this case, there is a half-life ( 15 minutes). After 15 minutes (if the route is not flipped again), the penalty value is reduced to half 500 , and after 15 minutes, it becomes 250. At this time, if the route has another jitter, the penalty value is increased by 1000 and becomes 1250. Before this, the route is used normally. If they shake once, it becomes 2250 , exceeding the threshold 2000 , this route will be suppressed, nor not updated. After 15 minutes, if it is no longer flipped, it is reduced to half 1125 (but still suppressed), so it goes through several half-lives until it is reduced to 750 (re-use limit) and the route is enabled again.
