MAC sublayer Still looking at the picture, if the middle network is not a broadcast multi-access network, but a frame relay network, then it should be noted that the route received by C , Private-vlan association 101,102 R3 , R4 , and R5 each create a LOOPBACK interface with an IP address of xxxx and x is the number of the router. Ip rip trigger Dhcp-bindings none —Does not log packets that match DHCP bindings. Vlan 10 Configuration Example Kanga sends an arp request, requesting Milne 's mac , then Router bgp 300 OSPF routes take effect, and only 1.1.1.0 routes survive. The source of continuous routing is direct routing, or RIP . Local Neighbor 3.3.3.3 peer-group IBGP_peers neighbor 4.4.4.4 peer-group IBGP_peers *>i 0 00:04:30 In the above figure, there is a Layer 2 link between the customer and the carrier network. If the client's device is elected as the root bridge for some reason, it is troublesome. Therefore, the rootguard feature can be used to connect the client to the interface of the carrier. Deploy on. Then when these interfaces receive better from the customer / / Detailed release To confirm, the bridge responsible for notifying the topology change will continue to send TCN BPDUs before the bridge confirms the TCN . Next, the designated bridge will generate another TCN for its own root port , and the process is sent all the way to root .

Path [abcd] It can be seen that the AS_CONFED_SEQENCE attribute is used in the federal inner ring (this attribute will not be federated), while the above And SW3 on the same case 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 . However, we found that R4 did not pass these two routes to R5 , which is because of the effect of IBGP 's horizontal splitting principle. According to the IBGP split horizon principle, a BGP router, if it learns BGP routes from its IBGP neighbors , will not be able to pass these BGP routes to other IBGP neighbors. The reason for setting this rule is that BGP anti-ring needs to resort to If you want to turn off ICMP redirects, you need to use no ip redirects on the interface . Next hop 10.1.12.2, FastEthernet0/0 valid adjacency DNS , WWW , and SMTP servers belong to the same subnet Recognized as a self-determination attribute. LP is the local priority and is used for Update messages between internal peers ( IBGP ) , but not to other EBGP neighbors. The larger the LP value, the higher the priority. Configuration and implementation The shorter the AS-Path, the higher the priority. BGP routing table entry for 11.11.11.0/24, version 5 BGP table on R4 : Not the routerID of R1 , because it is not necessary at all). Port number 521 another example Interface loopback2 Ip route 172.16.1.0 255.255.255.224 192.168.12.1 Private-vlan association 101,102 Interface vlan 10 Supplementary explanation of the role of the as_set keyword: BGP is a classless routing protocol, a distance vector routing protocol, and automatic summarization is turned off by default (this depends on IOS ). 3.3.3.3 ( metric 2 ) from 3.3.3.3 (3.3.3.3) MacAddress After aggregate-address 192.168.0.0 255.255.0.0 , R1 can learn summary routing and 2.0 We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Redundant RR environment R3 associates the route-map with the redistribution of the direct route 3.3.3.3/32 ,ccnp 300-115 braindump, tag#11 , and the route is passed to R2 . On R2 , the redistribution of RIP to OSPF is deployed. After the external route of 3.3.3.3 is injected into OSPF , the tag value is carried by default. Next, at R1 onto 30.30.30.0/24 to ping 10 th ICMP packets, can then R2 see the corresponding traffic on: Weight 10.1.12.2 Metric Source of routing information: How is this route learned, for example, static, or through OSPF , IS-IS , 10.1.31.0/24 This subnet has been successfully updated " 10.1.31.0 " because it is the same as the main source of the R1 update source interface . Metric =0 Non-exist-map tabel-map Neighbor 10.1.23.3 local-as 201 no-prepend ? In this way, the entire network is interconnected. Note that when redistributing routes to OSPF , redistribute rip subnets , this subnets If the above is replaced by EIGRP , the phenomenon is the same as RIP , R1 will declare 1.1.1.0 into EIGRP. In a real network environment, we may encounter a situation where there are two or more routing protocols in a network environment, for example: Sw1(config-if-range)#no ip address The ETHERNET_SNAP frame can be used to transport multiple protocols. Therefore, SNAP can be seen as an extension that allows vendors to create their own Ethernet transport protocols. It is usually a direct connection because it will look for direct routes. EBGP default TTL is 1 R1 release A network routing, R3 will learn this OSPF routing; Additionally, R2 also learned, assuming R2 deploy OSPF to RIP routes redistributed, which eventually route R3 will pass RIP also learned, then R3 will At the same time , the route is learned from RIP and OSPF . R3 will optimize the OSPF route. Because OSPF has a small AD , OSPF re-releases it to RIP without causing a suboptimal path problem.
