ccnp route 300-101 questions pdf

Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . Router(config) router rip Maximum MAC Addresses : 1 !! The maximum number of secure addresses, the default is 1 Set metric sets the metric of the routing protocol Write multiple commums in the same line, such as ip community-list 1 permit no-export 12:1111 does not take effect, can not delete these two values No need to connect directly. Only TCP connectivity is required. CCNP ROUTE contains all the contents of the book If you only want to detect the reachability of some next-hop devices, you can configure different route-map serial numbers to selectively use this feature (in the same route-map ). Layer 3 interface: routing interface ( no swithport or called routed port ), SVI interface The configuration of SW2 is as follows: If the topology is normal, SW3 has an interface that is BLOCK . This interface will not send BPDUs . Configuration example 5 (in the single routing protocol environment - OSPF out direction distribution list) VLAN [Experiment 6 ] There are subnet routes, the subnet route prefix length is different (matching and mismatching), and the matching route is taken. Route Control Overview 77 Switch(config-if)# switchport access vlan 10 + Configuration example: In order to verify this rule, we first maintain the basic BGP configuration. Introduce 100.0 by using network on R1 If it is unreachable, the suppression timer is started at the same time. If the timer expires, the same neighbor still advertises the But what if the A route is an OSPF external route? Access-list 1 permit any route-map PBR permit 10 match ip address 1 Router bgp 123 We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Version Redistribute static subnets 10.1.25.2 Ip route 100.0.0.0 255.0.0.0 null0 Then, R3 deploys the two-way re-release, so the process 2 route is injected into process 1 , then the route of the A network segment will be injected back into process 1 , so that the priority of O is greater than OE , so R1 and R2 directly ignore this. Strip routing. Will not cause other effects. Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only : 000a.8a07.8280 Length, or mask length. When paired with the above ACL , some students will even write Bgp dampening network redistribute Switch(config)# vlan 10 Len : Number of bytes of Sub-option Value , excluding two bytes of SubOpt and Len fields COMMUNITY Neighbor 3.3.3.3 route-map WT1 in neighbor 5.5.5.5 route-map WT2 in Seeing the summary route generated on R3 , AS_PATH inherits the detailed AS_PATH and presents it in the form of {100 , 200} , which can prevent the loop from happening, and will not cause hidden dangers due to the loss of the AS_PATH of the detailed route. . Note that the AS_PATH type in {} is AS_SET and is an unordered list of ASs . Mapping is only valid locally Neighbor 10.1.12.2 prefix-list 11 out 4 When a route oscillates (continuously fails, recovers), it is assigned a penalty value. The more the swing, the larger the penalty value and the constant accumulation. The configuration of R2 is as follows: Route tag TAG ( to be revised ) The above network is equivalent to network 1.0.0.0 ( network has a class declaration) Router bgp 345 ---------- Port 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: Encapsulate the ISL header and the new FCS on the basis of the original data frame Access permanent nontrunking mode and negotiate with the peer interface to make it a nontrunking link UDP The default load balancing method is round-robin R4#sh ip b 100.0.1.0 *> 100.0.2.0/24 Again, here is just a list of simple tools. In the actual network deployment, you need to flexibly select the most economical, scientific, and reliable tools and methods to deploy according to the actual situation. Incomplete Route-map test deny 10 External EIGRP Both R1 and R2 are connected to the 2.2.2.0 network. At this time, R3 goes to ping 2.2.2.2 . Because the static route of the outgoing interface is used, R3 thinks that 2.2.2.0 is a locally connected network, so ARP request is sent , R1 , R2 , can receive the request message, and both respond to the request message (the premise two Weight Applications *>i Network 5.5.5.5 0.0.0.0 area 0 MD5 digest : 0x49 0x3C 0x1F 0x79 0x15 0x00 0xC7 0xAE 0x0E 0xDC 0xDD 0xEF 0x93 0xA5 0xB6 0x26 Preemption enabled, min delay 30 sec Switching is the process of mapping layer 2 to layer 3 addresses andforwarding to a destination interface. 3.3.3.3 192.168.1.0 the OSPF routing but will be re-injected into the RIP (because we deploy a two-way re-release), this is the route Feedback , the route was filling back.

EBGP default TTL is 1 No-advertise no-export Id Rl , R2 , R3 using LOOPBACK neighbor relationship with the address of 1.1.1.1 , 2.2.2.2 , 3.3.3.3 , running OSPF such We spotted FIG, R1 and R2 between runs RIP to exchange routing information, R2 by RIP learned the R1 release over 192.168.1.0/24 and 2.0 / 24 routing information loaded into the routing table, labeled R & lt . While R2 and R3 and running OSPF , establish OSPF adjacency, R2 also from R3 , by OSPF learned the two routes: 3.0 and 4.0 / 24 , is also loaded into the routing table, labeled O . So, for R2 , it has its own route to the whole network, but inside R2 , we can understand this : it will not change the route learned from RIP .The OSPF route is told to R3 , and the route learned from OSPF is not sent to R1 as a RIP route . For R2 , although there is complete routing information in its own routing table,ccnp route 300-101 questions pdf, it is as if there is a gap between the entries of R and O , which cannot be exceeded.
