Redistribute connected metric 10 subnets route-map test network 192.168.23.3 0.0.0.0 area 0 // AS200 is the Primary AS and is used to configure the BGP process. R1 releases 10.0 , R2 releases 20.0 , and R3 issues 30.0 routes. Next, look at the different commands (keywords) configured on R2 . These BGP routes are learned by the specific router after the AS_PATH changes: Set the security address aging time to 50 min . Valid for secure addresses consisting of dynamically learned MACs We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows UDP At this time we look at the state of the trunk on SW1 : / / Used to match the BGP neighbors passed to my summary route , here is the IP of R4 No confirmation mechanism, anyone can initiate an arp request or response Errdisable recovery cause arp-inspection In the cmd of windows PC , the packet size after ping is the size of ICMP data , ping –l 1472 , and the generated packet is 1500 bytes. Neighbor 1.1.1.1 update-source Loopback0 The distribution list is deployed in a link state routing protocol such as OSPF . If the out direction is to be used, it can only be used in such a situation. Neighbor R2 unsuppress-map test Associate the static route of the next hop The physical interfaces belonging to a port-channel must have the same configuration as below. If the above into OSPF , is invalid, i.e., the static route is associated interface, in OSPF the network when the network routing number, and will not be declared into OSPF . The configuration of R3 is as follows: Match comprising 100 and 200 of AS_PATH Network 201 200 100.0.2.0 should choose R5 , check out the BGP table of R4 : Neighbor 1.1.23.2 send-community BGP routing table entry for 100.0.1.0/24, version 4 10.1.13.1 Re-routing release ( Redistributing Routing Protocols ) Routing Feedback (feedback) is a re-release in the deployment of routing requires a great attention to the phenomenon. As shown above, R5 will RouterB routing 100.100.100.0/24 passed to A , NEXT_HOP is 10.1.123.2 ; 3.3.3.3 The shorter the AS-Path, the higher the priority. R2 Floating Static Routes Network  official version ? Router bgp 200 DAI configuration example Blocking to forwarding state usually takes 30-50s (default 50S , ie 20+15+15 ), this time can also be adjusted by configuring the spanning tree timer. Must be zero METRIC On R2 and R3 , there are two OSPF processes. If shown, one is OSPF1 and the other is OSPF2 . Note that this dual process is mainly implemented on the two ASBRs R2 and R3 . Implementation points !! On R1 , Fa0/20 port trimmed only vlan 1 and 10 , because this Full-duplex MAC : The physical layer operating mode provides access when full-duplex. 192.1.168.3 3 0003.44d6.c52f 2BB648EB interface-id 1bdb223f If R1 turns on auto-summary and network 1.0.0.0 mask 255.0.0.0 , it is advertised to R2 summary route 1.0.0.0/8 If a DHCP relay is also deployed on the switch, the switch adds the relay address to the DHCP packet. R1#show glbp 100 i S0 DCE Update timer update timer Neighbor 10.1.13.3 route-map test out VLSM support Just match (65000) Vlans allowed on trunk RIP is re-released into OSPF If the output is too much, you can use the pipe character: sh cef interface s0/0 policy-statistics input | in 30 ? Show ip b rib-failure Verify the value of experiment 1 ORIGINATOR_ID On the trunk port, as mentioned earlier, port-security can also be activated . The maximum number of secure addresses can be configured on the trunk interface, which can be based on interface configuration ( valid for all VLANs ) or VLAN- based . as follows: Message life Router b 300 Received a Layer 2 frame. The configured static network path is redistributed into OSPF . In this way, when the intranet user needs to access the Netcom resources,ccnp switch forum, because of the details of the network access, go to OR1 . To access other resources, take the default route to OR2 . Then the configuration on R3 : Access-list 1 permit 11.11.11.0 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 The red font part of the above output is the layer 2 MAC information and so on. Network 11.11.11.0 mask 255.255.255.0 Link type Link types Local origin ? Mode 5.5.5.5 ( metric 2 ) from 5.5.5.5 (5.5.5.5) Bgp default local-preference 500 // Modify the default LP value Dampening takes effect only on EBGP routes and invalidates IBGP routes. Flag field LSB = TC MSB = TCA 200 i Protocol overview Let's analyze that SW1 inserts the DHCP request message from the PC into option82 and then sends it to SW2 . Via SW2 Port 3.3.3.3 Can the other party receive the route? What if R1 is RR ? Note that CLIENT does not know its identity. : ccnp After the test is verified, (in the case that the basic configuration of BGP is correct) , the network segments of the looback interface of R1 and R2 are learned by static routes or dynamic routes. The establishment of BGP neighbor relationships is fine , but if both ends use the default. If the routes refer to each other, the BGP neighbor relationship cannot be established. This is for the purpose of anti-ring. When using static, the default is ok.
