If you specify the * i ^100_ Route-map test permit 10 Set origin incom R2#show cef interface f0/0 FastEthernet0/0 is up (if_number 4) AS Hops 1 / / This is used to match 11 routes R1 RIPv1 Then all the 172 network segments on R1 and R2 are suppressed. At the same time, since the route-map test only matches the 1.0 and 2.0 network segments (in AS100 ), this summary route, AS_PATH only inherits AS100 , which is 300 100 ; Neighbor 10.1.23.3 local-as 201 [no-prepend] [replace-as] [dual-as] Now let 's do the following configuration on R2 : Port-Security supports activation on the trunk configured as follows * i Take the configuration of R2 as an example: s> 172.16.1.0/24 ...... 10.1.25.2 Two-way re-release on R2 . Under normal circumstances, R1 can learn 3.3.3.0 , and R3 can learn 1.1.1.0.

Private-vlan association 101,102 Hash Neighbor 4.4.4.4 update-source Loopback0 neighbor 10.1.25.2 remote-as 200 description Network For the original attribute, it specifies the source of the route update, which has the following values: VID Route-map WT1 permit 20 match ip address prefix-list 2 set weight 100 The following figure is the open message content of the negotiation capability parameter (note the ORF part) The IEEE802.3 frame can be divided into the following categories according to the values ​​of the DSAP and SSAP fields: R2#show adjacency detail Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only Since R4 and R5 are federated EBGP , there are also TTL problems, so if they use LOOPBACK to establish neighbor relationships, you should pay attention to setting ebgp-multihop . BPDU There are two types: configuration BPDU and TCN SW1 (config-if) # glbp 1 priority 120 !! Priority defaults 100 , the highest priority becomes the AVG , under equal priority, the maximum IP interface becomes the AVG . Default " AVG preemption" is off Exit Ip route 0.0.0.0 0.0.0.0 192.168.123.1 SW1 (config-if) # glbp 1 priority 120 The default is 6 update cycles, which is 180s . The route entry tag when an entry with a larger hop count is received Match ip address prefix-list 1 2 Next hop The second command is to adjust the AD value for external routes, inter-area or intra-area routes . Reposted FAQ 49 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 . C 1.1.1.0 is directly connected, Loopback0 2.0.0.0/32 is subnetted, 1 subnets 20 100 i When a network is directly connected, the interface is not "activated" and attempts to establish a neighbor relationship. BGP neighbor relationships need to be manually On the untrust interface, create a security entry by manually configuring ARP ACLs on B. Of course, you can isolate the two switches in three layers, for example, add a router. C 10.1.12.0 is directly connected, Serial0/0 When the look-up table, the binary 0 , . 1 bits match, and for an exact match, i.e. purpose MAC and CAM table MAC needs Le keyword is not written, then the default is greater than 24 less than 32 By modifying LOCAL_PREF to affect the flow properties Between ASs , and within AS , BGP hopes that the IGP protocol can be handled by itself, so the administrative distance of IBGP routes is set to a large AD value of 200 .

Ip route 10.1.12.0 255.255.255.0 10.1.1.2 Neighbor maximum-prefix xx Neighbor Access-list 1 permit 192.168.1.0 Use route summarization! Looking at the picture above, in the previous scenario, we need to use 3 fine routes, but here we can achieve the same effect by using only one route. This route is the summary route of the three detailed routes in the previous scenario . A direct benefit of this configuration is that the router's routing table entries are greatly reduced. This mode of operation is called route summarization. Route summarization is a very important network design idea. Usually in a large and medium-sized network design, network and routing optimisation must be considered at all times. Route summarization is a time we need to shut down.
