( Optional transitive ) The configuration is as follows: Multi-vendor routing environment Next Hop SW2 is the core layer switch, deploying DHCP relay r >i1.1.1.0/24 Route-map COST1 permit 10 match ip address prefix-list 100 IGRP for OSI networks Metric for redistributed routes Mobile routes Show ip cef exact-route src-addr dest-addr R4 In the federal scope, the member AS number is pushed into the AS_PATH , but not published outside the federation, and the AS_PATH of TYPE3 , 4 is used . As shown above, the position of the line is 16+4=20 , so we get the summary address: 192.168.0.0/20 , which is the most accurate summary address. Conditional delivery of default routes Use set excommunity cost x to set in route-map AS_CONFED_SEQUENCE and AS_CONFED_SET IP Routing Table 5 AS number of the AS neighbor Trunks can be statically configured or negotiated through DTP . Show run int | include bia can see all the MAC , the first MAC will be used by the spanning tree, which is the CPU 's MAC . Next is the MAC of each Ethernet interface . Origin file flash:CCIE.txt The smaller the RID of a BGP neighbor is, the higher the priority is. Etherchannel port does not support pvlan STP operation Solution: Modify the routing protocol management distance 98 ^100$ Routing entry for 192.168.1.0/24 Ip rip trigger 31 Router bgp 100 12:11 12:1111 no-export this comm list, to delete the no-export , then Path The configuration on R3 is as follows Option82 192.1.168.1 3 0003.47d8.c91f 2BB6488E interface-id 21ae5fbb Next is the re-release of EIGRP to OSPF : BPDU packet Address 10.1.12.1(10) Associate route-map when route is republished (typical case) Aggregate-address summary address as-set advertise-map Then call the track object in the route-map Match ip address 1 set metric 10 802.1Q support 4096 Ge VLAN The number of addresses. The switch assigns MAC addresses in order 10.1.23.2 IP nodes can communicate, and communication is actually the process of data interaction. Data interaction requires network devices to help us transfer data between two communication nodes. When the router (or other Layer 3 device) receives an IP packet, the router will find out the purpose of the IP packet in the Layer 3 header. 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; After the bgp bestpath compare-routerid command is configured , the principle is skipped and the route with the smallest RID is selected as the optimal. Hostname R3 interface s0/0 Not advertised to any peer Match the AS_PATH that does not contain any AS number , that is , the route in the AS . Enabled by default, if an interface DOWN up,ccnp route final, BGP answer immediately suspended. Route-map OSPF3to2 permit 20 match tag 20 Prefix-list ? 1 Path Not advertised to any peer 200 100 Secret level Per packet load-sharing is disabled IP unicast RPF check is disabled Inbound access list is not set Outbound access list is not set Clear the dynamically learned security address entries on the interface. Ip route 1.1.1.0 255.255.255.0 serial 0/0 Violation Mode : Shutdown !! After the violation, the default is shutdown Aging Time : 0 mins Receiving behavior *Mar 4 07:02:23.473: DHCPD: relay information option exists, but giaddr is zero. The setting of the weight value can only be done locally and cannot be passed to any BGP neighbor. * i100.0.2.0/24 The route weight generated by the local network is 32768. ? Network without mask is a class declaration, plus the mask is no class declaration IGRP In VTP server mode of SW3 is turned on VTP pruning after, Client of SW1 and SW2 are learning and also to open their VTP pruning . Data forwarding mode 13 Network Show ip dhcp binding Show dhcp binding on DHCP server Ip dhcp relay information trust-all Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only RIPv2 : 000a.8a07.8280 Bridge ID in the MAC , is the backplane of the switch MAC , the port ID in the MAC switch port MAC , all the view switch mac available The route to the nearest BGP NEXT_HOP route is the route with the smallest IGP metric to the next hop router. After the basic configuration is completed, the BGP table of R4 is as follows: Router ospf 1 Use a static route to the next hop Method three: default-information originate 100 i Network 100.0.2.0 mask 255.255.255.0 neighbor 10.1.25.5 route-map test out Local origin Configuration and implementation Show ip b rib-failure AS_PATH , LOCAL_PREF and MED , and added ORIGINATOR and CLUSTER_LIST for anti-ring. The protocol for RSTP BPDU is 2 and the version is 2 . If the DHCP discovery message sent by the client does not contain the client-identifier , the hardware address can be used to identify the terminal device. The configuration commands are as follows: Port Network 11.11.11.0 mask 255.255.255.0 This experiment mainly verifies that automatic summarization does not occur at the boundary of the main class network: Next Hop Next Hop Longest matching principle Set interface specifies how to send such a packet set ip default next-hop specifies the next hop to be forwarded set ip next-hop specifies the next hop to forward Neighbor 1.1.23.2 send-community Therefore, the role of the no-prepend keyword is: Do not prepend local-as to updates from ebgp peers . If you advertise the route to the EBGP neighbor of the primary AS , the secondary AS number is not attached . FastEthernet1/0 Metric The default is shutdown , optional protect , restrict The above command only re-advertises OSPF external routes E1 and E2 into BGP. Access-list 1 permit 1.1.1.0 Neighbor table Undoubtedly, R3 will preferably OSPF the B route, since OSPF the AD small, so that R3 is formed suboptimal paths, which go B segment will choose R1-R2 -R4-R5 this path. Furthermore, in the routing table of R3 , the route on the B network segment is O , then even if R3 does a re-release from RIP to OSPF , the re-release is definitely a failure, because we have said before, the routing protocol is heavy. The release will only live in the routing table, and the routing table on the B is OSPF , so the re-issue fails.
