Redistribute ospf 3 subnets route-map OSPF3to1 router ospf 2 In R2 opened on loopback interfaces 2.2.2.0/24 , R2 both redistributed RIP into OSPF , they redistribute directly connected into OSPF Basic configuration of Layer 3 switch R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. The configuration of R1 is as follows: R1(config)# access-list 1 deny 11.11.11.0 R1(config)# access-list 1 permit any R1(config)# route-map rp permit 10 R1(config-route-map) match ip address 1 R1(config )# router bgp 100 Fa0/22 1,10,20,30 2.2.2.2/32, version 55, epoch 0, per-destination sharing 0 packets, 0 bytes You can use ^ at the beginning of a range to exclude all characters in the range, or you can use an underscore _ to specify an interval. In the BGP process: neighbor xxx default-originate to pass the default route to a specific neighbor. This configuration does not require a default route in the routing table. A bit like OSPF 's default-originate always AS_PATH , and AS_PATH only when routing out this AS or BGP routers to update EBGP will change when neighbors in AS inside will not change, therefore, in the AS internal, anti-ring requires the use of split horizon. So how to solve the problem that R5 ca n't learn routing? [Start fast exchange] Into, both are indispensable, such as 192.168.1.0/24 and 192.168.1.0/25 , although the network numbers of both are the same, both are 192.168.1.0 , but the two are definitely two different routes, two different Routing prefixes because their prefix lengths are not the same. Next Hop The length is 2 bytes, indicating the frame type. When the value is 0x8100 , it indicates an 802.1Q Tag frame. If a device that does not support 802.1Q receives such a frame,ccnp route syllabus, it will discard it. Neighbor 4.4.4.4 update-source Loopback0 neighbor 10.1.25.2 remote-as 200 MED , choose 3 : 1 BGP supports MD5 authentication. To enable MD5 authentication on the TCP connection between BGP peers , use the following command: Match ip address 1 set metric 10 Each cluster has a unique cluster ID 2 state changes, last state change 00:07:34 Virtual IP address is 10.1.1.254 The redistribute local route learned from the IGP routing protocol enters BGP , and the MED value inherits the metric in the IGP protocol. Aggregate-address summary address summary-only Therefore, BGP automatically summarize ( Auto-the Summary ) Summary Only redistributed redistributed routes, and the use of network command routing incoming class declaration ways. Currently CISCO IOS turns off automatic summarization by default. UDLD 100 i status Underline, matching any separator such as ^ , $ , space, tab , comma, { , } 46-1500 bytes; set mtu xxxx under the interface , which means this, and generally does not allow Manual network through BGP , which originated from IGP , because BGP network must guarantee the network About IP Routing 5 AS_SEQ type is {100 , 200} in this segment is AS_SET type. So AS_SEQ the AS_PATH used to identify the origin of this summary route, it is ordered AS list, in addition AS_SET this AS_PATH type used to identify the details of pre-aggregated All devices complete the basic configuration and establish BGP neighbor relationships. The yellow area is the federated member AS . 10.1.13.1 802.1Q support 4096 Ge VLAN Local After R2 show run , I found: [^act]$ Next Hop TCN BPDU RIP and OSPF IP Routing Overview ? 0 100 0 200 i 5.5.5.5 The update is sent. At this time, both parties have their own routes, but 1.1.1.1 cannot ping with 2.2.2.2 . basic concept IGRP/EIGRP Configure all interfaces as passive and manually activate specific interfaces: The Conditional inject is configured as follows (in BGP routing process mode): Root port: The interface that receives the optimal BPDU is the root port. This is the closest ( cost minimum) interface to Root . RIP-1 compatibility RIPv2 sends updates in the form of broadcasts, enabling V1 to receive By default, this database is dynamic, which means that when the switch is restarted, all entries in the database are lost. The result of this event may cause network disruption. So we can store this database as a file, this is the DHCP snooping database agent . The configuration command is very simple, global command: Configuration command 46 The federated AS number in AS_PATH is used to avoid loops within the federation 200 Let's review the 13 routing rules of BGP . In this lab manual, we will verify the main entries in the routing rules and familiarize ourselves with the various properties of BGP . 200 i Type Set tag 10 TYPE indicates what type of frame this is, such as Ethernet, Token Ring, etc. Matches 100~109 , and 10 because " ." also contains spaces Port-Security supports nonegotiating trunk interface ? IP Routing Overview Metric * i100.0.2.0/24 Y R2(config-router)# redistribute eigrp 100 subnets Ip address 192.168.10.254 255.255.255.0 Used to advertise available routes, revoked routes, or both, Then according to our thinking, on the R4 should be able to see the choice of 100.0.1.0 is R3 is 3.3.3.3 , go to Redis static route-map test Other configuration commands Authenticate DAI working mechanism Manual network through BGP , which originated from IGP , because BGP network must guarantee the network DMZ-Link Bw 12500 kbytes Match abd , abcd , abcdefg, etc. Configure no switchport ( routed port ) Layer 3 interface Note that PEs in an MPLS VPN environment do not have this limitation. Network The configuration of R2 is as follows: For example, in R3 viewed on R5 sent me 6.6.6.0 of this OSPF external routes, you can see the tag field is 600 (automatically inherit the AS_PATH ) And this time, R3 the OSPF redistributed into BGP , the default is not automatically restored AS_PATH attribute, so you need: MAC address * i Verify again, instead of detailed routing, use a summary route of ip route 10.0.0.0 255.0.0.0 , the next hop is R3 , the effect is the same as above, also take R3 . Therefore, as long as it is not the default route, as long as there is such a matching route in the routing table, the route is taken preferentially, and the route-map is taken without the route . No synchronization For the next hop and route tag, see Volume I, page 189 . 10.1.12.1 from 10.1.12.1 (1.1.1.1) Redistribution of class, classless routing protocols 46 1 When the following conditions occur, activation of punishment ( Violation ): CISCO data forwarding mode The above figure only makes basic BGP configuration, releases 1.0 and 2.0 on R1 , does not summarize, and 1.0 and 2.0 BGP routes received by R4 .

Configuration case 1,20,30 200 i Forwarder 1 State is Active R3 Switchport mode private-vlan host The Ip helper-address command is configured on the Layer 3 interface that receives the broadcast discovery packet sent by the client , or "blocks" the broadcast DHCP packet. For example, if it is a Layer 3 switch, use the access. interfacing PC , then you should configure the VLAN 's SVI interface. Offset-list 1 out 1 serial 0/0 *> 100.0.2.0/24 Configuration command 57 Connected, and can update and deliver BGP routes. Hello time root bridge sends configuration BPDU default interval 2 is S Router(config-router)# distance eigrp internal-distance external-distance The smaller the MED, the higher the priority 4 Ip prefix-list 10 seq 5 permit 172.16.10.0/24 ip prefix-list 11 seq 5 permit 172.16.11.0/24 route-map test permit 10 This is the general case, of course, there are two situations, it depends on the specific environment and the specific routing protocol. If an external route carrying a tag is advertised on R1 and OSPF is redeployed to EIGRP on R2 , then the route is advertised. 10.1.34.3 from 10.1.34.3 (3.3.3.3) Off: EtherChannel not configured on interface 16 None When R5 is updated to EBGP neighbor R2 BGP route 5.5.5.0 , NEXT_HOP =192.168.25.5 , this attribute will always be followed by this BGP route in AS234 . At this time, for R4 and R3 , I don't know how to go to 192.168. 25.5 , so the 5.5.5.0 route cannot be properly loaded into the routing table. One solution is to R2 in the IGP injection route 25.0 This external routes, the other is R2 its IBGP neighbors using the Next-Hop-Self , modify this prefix NEXT_HOP properties.
