14 8 bits 200 Standby is 10.1.1.252, priority 100 (expires in 7.572 sec) Do not send outside local AS (well-known community) Configuring a sample RIP environment (Note that this feature is not supported in truncated switching mode on 6509 switches ) RIP V1 supports a maximum of 6 and defaults to 4 equivalent load balancing. And does not support verification. V2 supports verification. The configuration of R1 is as follows: Regular expression No synchronization no auto-summary No-advertise Vlans allowed on trunk 100.0.1.0 the BGP route, preferably up to R5 . New link Link1 between A and Root Using route reflector 23 3.3.3.3 After R2 show run , I found: Match ad , abcd , aaabcd, etc. ? Since the configuration of the first experiment Rl , therefore R2 Flights 13 segments, it is preferable that Rl , this time in R2 a clear click BGP neighbor Rl , and the Rl BGP connection DOWN , R2 Flights 13 routes and preferably the R3 , After R2 and R1 restore the BGP connection and receive the 13 route update of R1 again , R2 is still preferred to R3. None Switchport access vlan 10  open 10.1.23.2 100 If there is no tag , mark the PVID of the trunk port and proceed to the next step. Total MAC Addresses 0 The configuration of R1 is as follows: The configuration on R3 is as follows: RIP and OSPF *>i10.1.23.0/24 When a data frame is sent from the Hybrid port, the switch determines whether the attribute of the VLAN on the port is Untag or Tag . If it is Untag , first strip the VLAN tag of the frame and then send it; if it is a Tag , send the frame directly. 8 8 8 8 Ip community-list 30 permit 300:30 route-map PA permit 10 MAC address Network 100.0.1.0 mask 255.255.255.0 Otherwise the flag field is obtained by some calculation (as part of the verification process) Match ip address prefix-list 1 R3 and R4 update the routes in AS1 and AS2 to R5 and R6 at the same time . If R5 is required to go to AS1 , take route R3 and go to AS2 . The traditional STP , which is 802.1D , is that all VLANs share a spanning tree. The advantage of this is that the switch does not use too much resources to calculate multiple spanning trees. However, the defect is that the port is fixed through the block . As a result, traffic on the network only goes to one side, and some links have no traffic at all, which wastes bandwidth. When both DSAP and SSAP take a specific value of 0xaa , the 802.3 frame becomes the ETHERNET_SNAP frame. The default is shutdown , optional protect , restrict SW1(config-if)# switchport trunk encapsulation dot1q SW1(config-if)# switchport mode trunk EGP Show ip bgp route prefix Match ip address 1 set tag 10 Field name Complete the basic configuration STP port state transition process No synchronization learner AS65102 as a transit region ( trasit AS ), the AS inside BCDE running the OSPF , such that AS within reachable; D and C did not run At the time, it is already " 200 i ", so doing prepend can only be inserted in front of 200 i , please pay attention to the difference from the previous one. ? Port-Security After completing this configuration, we can show it: BGP anti-ring is implemented through AS_PATH , and AS_PATH is only changed after the route leaves the AS . Therefore , IBGP does not have EBGP anti-ring capability in the AS . To prevent loops, BGP routers will not be from IBGP neighbors. The learned route is advertised to other IBGP neighbors. Link type Link types Double-point bidirectional routing re-release 91 Aggregate-address summary address as-set advertise-map This is a simple method of data offloading and path redundancy using the longest matching principle. The cost of the route. 10 FastEthernet0/1 If a designated discarding interface issue proposal after, did not receive Agreement , it will slowly transition to the forwarding state, this process is a traditional 802.1D the listening-learning-forwarding process. This situation may occur when the peer switch does not understand the RSTP BPDUs or the port of the peer switch is blocked . The BGP update package is as follows. You can note that the length of the AS is 2 , which is " 300 , 100 ". Note that this is an ordered list of ASs . Then look at the R4 's BGP table: Neighbor 4.4.4.4 next-hop-self AD value and back door 1,20,30 Multiplication character SW1#sh int trunk The next hop of the path is unreachable. The main routing table version is injected into the last table version in the main routing table. Where min ( holdtime ) is the minimum value of holdtime between two BGP neighbors. Mapping is only valid locally All devices complete the basic configuration and establish BGP neighbor relationships. The yellow area is the federated member AS . In other words,ccnp route syllabus 2017, R1 is not required to have a default route locally. *>i100.0.1.0/24 When a router connects through a multi-access medium such as Ethernet, a dynamic mechanism is needed to discover each other, such as ARP . ARP can map Layer 2 addresses to IP . If it is a frame relay multipoint link, the adjacency relationship can be learned by using an address resolution protocol, a mapping table, and the like. B 3.3.3.0 [200/0] via 2.2.2.2, 00:03:01 Configuration example 0 0 192.168.67.6 Router(config-dhcp)#network [network address][subnet mask] Type echo protocol ipIcmpEcho 10.1.1.2 source-ipaddr 10.1.1.1 frequency 10 Written in front of the words: Neighbor 10.1.12.1 capability orf prefix-list send neighbor 10.1.12.1 prefix-list FILTER in Neighbor 1.1.1.1 route-map COST1 in neighbor 3.3.3.3 route-map COST2 in 10.1.13.1 R2(config)# access-list 1 deny 192.168.3.0 R2(config)# access-list 1 permit any R2(config)# router rip [Experiment 5 ] There are subnet routes, the subnet route prefix length is different (but both match), and the longest match The configuration of R2 is added as follows: If the interface is configured as a hybrid interface Not advertised to any peer Local Length of the remote-ID type Ip dhcp pool BIND The configuration of R3 is similar. Neighbor 2.2.2.2 peer-group IBGP_peers When a BGP router sends a route update to its EBGP neighbor, it cannot carry the LP attribute. The LP value of the EBGP route received by the peer is empty. Ip route 0.0.0.0 0.0.0.0 192.168.23.3 Regular expression Neighbor 4.4.4.4 update-source Loopback0 neighbor 10.1.25.2 remote-as 200 The weight of the BGP route generated by the local summary is also 32768. In the route-map in the set community As a result, on R2 , the OSPF route 1.1.1.0 in the routing table and the 192.168.12.0 directly connected network segment that is declared into the OSPF process are all announced to RIP , and R1 can learn the two routes through RIP. , as shown in the red bold part below. BVI Bridge-Group Virtual Interface IP layer connectivity. Used for unidirectional link detection, mainly for fiber links. Devices that need both ends of the link support UDLD Topology change mechanism (delivery) 16 bits TCP / IP Volume II of this note contains TCPIP Routing Volume BGP almost all the content parts, and a detailed expansion BGP re-released to IGP The IBGP neighbor relationship is as shown in the figure. The neighbors are built using their respective loopback ports. After receiving the route, R2 continues to pass the IBGP neighbor R3 . In this case, R3 is the RR . Therefore , the route sent by the non- client IBGP neighbor is forwarded to its client R4 . At this time, R3 adds the ORIGINATOR and CLUSTER_LIST attributes to the route. , where the ORIGINATOR attribute is R2 's routerID is also 2.2.2.
