Let's look at the following example: Difficult to resolve As a result, R3 updates the BGP route to R4 , and next-hop will be replaced with R3 's loopback interface IP . Route-map test permit 10 Set origin incom 10.1.13.3 Advance Root SW1 receives the RLQ request and immediately responds with an RLQ response to inform that it is still alive. Path control 0 100 0 The VTP Server and clients synchronize the database with the highest revision number; Metric=BW+DLY , where DLY is the accumulation of DLY along the inbound interface of the route ,ccnp tshoot youtube, and BW is the minimum interface bandwidth. Obviously through DLY Router b 300 Ip address 100.0.1.1 255.255.255.0 Pointer to the target: The pointer does not point to the router's direct connection to the destination network or to another router address in the directly connected network , or to the local interface of the link. A router that is closer to the target network is called a next hop router. Gateway of last resort is 172.16.3.0 to network 172.16.0.0 Since the AS_PATH attribute does not change within the AS (only when the route leaves the AS ), the AS inner loop has a horizontal splitting mechanism, and the route reflector actually relaxes the horizontal splitting principle. This will bring some hidden dangers to the loop. Therefore, the route reflector needs to use the following two attributes to prevent loops: 2.2.2.0, but the update is 2.0.0.0 after the summary 100 Configure Port Security Rate Limiter R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . If R1 starts auto-summary and introduces 1.1.1.0/24 in the way of re-distribution direct connection , the subnet will be automatically summarized to R2. Origin IGP, metric 0, localpref 100, valid, internal On this topic, the individual feels that there is no need to study it. It does not make much sense for the research of class-based routing protocols. No matter the actual application or the LAB exam, it is no longer involved, and you are interested in making it yourself. Set the interface cost The same prefix is ​​obtained through different protocols, first than AD , and later than metric It is allowed to write multiple next hop IPs , but these IPs must be the interface IP of the directly connected router . Access-list 1 permit 3.3.3.0 router rip Part of static configuration, part of dynamic learning 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 . 1) Clear the MAC entries learned from all interfaces except the one that received the TC BPDU . Although this action may cause a brief burst of flooding in the network, it is also beneficial to refresh the CAM table and clear the stale entries. Configure native VTP mode r >i1.1.1.0/24 Modify the TAG of the summary LSA of the ASBR notification Match community 11 exact-match // strict match Ip address 192.168.100.254 255.255.255.0 Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS Distance 100 192.168.12.1 0.0.0.0 1 Single match includes a plurality of conditional statements, logical or operation; multiple match when the statement, using the logic and operation. 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 . Baby giant frame is larger than the standard MTU 1500 bytes, but less than 2000 bytes Feature VLAN: 6 Match ip add pre 1 Bgp confederation identifier 345 bgp confederation peers 64512 neighbor 4.4.4.4 remote-as 64512 Ip prefix-list huizong permit 172.16.0.0/16 ip prefix-list mingxi permit 172.16.1.0/24 ip prefix-list xiayitiao permit 10.1.24.4/32 route-map RP_mingxi permit 10 Must be zero When using Ip default-network to refer to a network locally, if the network number exists in the routing table, the router will designate the network as the default gateway. Set community no-advertise route-map setCommu permit 10 router bgp 300 This is not much to say? For PBR , when creating a route-map , it is all permit . R3 sets the tag when injecting the route. VLAN 15 bits with the current 10 th, then the support up to 2 of the 10 power = 1024 th VLAN advertise-map and summary-only when combined, Aggregate-address lower address all the details are summarized suppressed while advertise-map entries that match all the details if hung up, the summary route disappeared, (so long as advertise-map matching There is one in the detail, the summary is in); and the summary route inherits only the BGP path attribute of the advertise-map matching detail route.
