Although RIP is running between R1 and R2 , the routes of 1.1.1.0 and 2.2.2.0 are updated with each other , but since R1 is from RIP and his VTP Operating Mode : Server Maximum VLANs supported locally 1005  Access-list 1 permit 172.16.10.0 Used for unidirectional link detection, mainly for fiber links. Devices that need both ends of the link support UDLD Local Exit 3.3.3.3 20.20.20.0/24 S0 192.168.12.1/24 r1 ? R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Set the interface to nonegotiate and do not send DTP frames. If the configuration is non-negotiated, you must manually configure the interface mode as access. ... (maximum 25 ) Limit the maximum number of prefixes accepted from the neighbor. If this number is exceeded, the router will close the BGP connection with the neighbor. Apply clear ip bgp Set interface In addition, if there are multiple links between two EBGPs and use their respective Loopback ports as the source , you should also pay attention to the configuration. Ebgp-multihop 2 (because loopback spans two routers, including this one ),ccnp tshoot exam booking, and must also refer to static routing to the other's loopback interface. ) Then between R3 and R4 is the federal IBGP relationship, and between R4 and R5 is the federal EBGP relationship. Ip default-network 172.16.0.0 The routing protocols that support TAG are: RIPv2 , EIGRP , OSPF , ISIS , BGP Configuration and implementation The incoming route is passed from the external AS . The NH is the EBGP peer that advertises the route , and the NH will follow the route to pass within the AS without change (unless a policy is made), always pointing to the next AS (advertise the route) the EBGP peer interfaces IP ). Neighbor RC-ip remote-as 100 No off default route above configuration, adding a destined 13.0 network routing next hop is R3 , the PC to 13.0 data network switch to R3 proof ip default next-hop priority routing detail below, above Default route. If R2 on ip route 1.1.1.0 255.255.255.0 null0 , this time there is no routing table OSPF of 1.1.1.0 routing the unsuccessful thus re-release, so R3 can not learn the 1.1.1.0/24 route; A sends a data frame to B requesting to establish a reliable connection-oriented connection. Interface mode, configure the interface as DAI trusted , the default is untrusted Therefore, from here we can see that the route summary is a risk of looping. One way to solve the above problem is to add a static route on the Layer 3 switch: ip route 192.168.0.0 255.255.0.0 null 0 , this way, when it receives access Configuration example 2 ( -RIP in a single routing protocol environment ) Distance vector routing protocol Exactly the same, except that the list of AS numbers belong to the local Federation AS We can R4 use the bgp always-compare-med command to force R4 compare routes MED The experiment is completed here, we set MARK , then we will analyze the impact of various attributes on the routing. BGP policy Match ip address prefix-list 1 set metric 200 The prefix list contains the serial number, matching from the smallest Router bgp 64513 no synchronization Garbage colletion/flush timer Root received the TCN , sent back a TCN ACK to C . 201 200 100 Ip prefix-list 1 permit 1.1.1.0/24 route-map test Network 100.0.2.0 mask 255.255.255.0 Configuration example _100$ The configuration of R3 is as follows: 3.3.3.3 Passive-interface Fa0/0 ? The metric is a value) The aggregate-address command is used for BGP manual summarization. The following is a detailed explanation of all subcommands of the command. Ip community-list 11 permit 100:11 Ip address 192.168.100.1 255.255.255.0 Bgp dampening ? When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 The process learns the external route, so the update source here is R2 . If the static route configured by the outbound interface is configured, the router considers the destination network segment as a local direct connection . Therefore , when the RIP is in the network , it will be announced. Field name Activate Port-Security on the interface 5.5.5.5 ( metric 2 ) from 5.5.5.5 (5.5.5.5) In general, a Layer 3 switch contains two types of ports: Layer 2 interface L2 and Layer 3 interface L3. Route-map PBR permit 20 match ip address 2 So how do you perform an accurate calculation of the summary route ? Let's look at an example: RIP-2 Only 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. FastEthernet0/0 BGP policy Each RIP message contains routing entries, up to 25 , and more than one message is required. 192.168.1.0 will pass the default route of 0.0.0.0 into RIP , and R2R3 will learn. We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Ip route 0.0.0.0 0.0.0.0 192.168.23.3 Report routing information. When no port-secuirty mac-address sticiky is typed at this time , all sticky secure address entries become dynamic secure address entries ( SecureDynamic ) An important improvement in RSTP is the rapid transition of ports. The traditional STP algorithm needs to go through several timers before transitioning an interface to the forwarding state. In order to get a fast convergence of the network, we may adjust the timer, but this method may affect the stability of the network. Port Fa0/20 The network learns the route learned from the IGP routing protocol into BGP . The MED value inherits the metric in the IGP protocol. Between R1 , R2 and Layer 3 switches, it is assumed to be a static routing environment. So now, we hope that users under R3 will flow in the direction indicated by the red dotted arrow when accessing the production server, and will flow in the direction of the blue arrow when accessing the office server. !! Take the default route ? The physical interfaces belonging to a port-channel must have the same configuration as below. These modes generally only be on high-end Cisco device applications , such as 7200 series routers . Or 12,000 Series routers . Command : ip route-cache optimum show ip cache optimum The decision process of BGP is to use the local routing policy for the routes in ajd-RIBs-IN , and put the selected or modified routes into Loc-RIB and 86025 1.1.1.1 (metric 129) from 4.4.4.4 (4.4.4.4) ? Route 3 : AS_PATH : 500 100 R1(config-router)#redistribute rip subnets tag ? Authentication (16 octets) !! When the route matching ACL1 when It can be activated in interface mode or in global mode, which is different. Implementation point 42 9 Looking at the above picture, we made a manual route summary on R3 . This summary route was generated by R3 and passed to R4 . At this time, the AS_PATH of this summary route is 300 , and the detailed route under it is lost. AS_PATH attribute, then if R4 and R1 or Scanning messages on the intranet. The destination addresses of these packets are some unknown addresses that start with 192.168 , or even addresses that do not exist at all. The packet is sent to the gateway, which is the Layer 3 switch. Since the Layer 3 switch is configured with the default route, these packet destinations are matched by the default route and directed to the egress router, and the summary route is deployed on the egress router. Although the destination address of the packet does not exist in the internal network, it is an IP in the summary route , so it is forwarded back to the Layer 3 switch by the egress router. Then the Layer 3 switch forwards the packet according to the default route. Back to the router, this forms a loop of data.
