ccnp route 300-101 study guide

After completion of the above-described basic configuration, we can at R5 to see the phenomenon, R5 simultaneously from R2 received 100.0 route segment, also from R3 received from the R1 release of 100 route segment, the final R5 will The route of R2 is preferred , which is matching this rule. A CFI of 0 indicates a classic format. Route reflector RR *>i100.0.2.0/24 Set comm-list del delete route-map test permit 20 When an RSTP switch detects a topology change it will: 5.5.5.5 5.5.5.5 You can enable this feature by using the spanning-tree loopguard default global configuration command. Set the interface to DTP dynamic negotiation, optional auto or desirable Address family identifier. When the value is 2 , it indicates the IP protocol. 30 For specific supported equipment, see the official CISCO documentation. 100 100 Sw(config)#interface range fa 0/3-4 Routing entry for 100.100.100.0/24 Preferably EBGP route At this time, he himself will still forward if he receives the data packet to 3.0.0.0 , but will not forward to other rips. 1 network entries using 117 bytes of memory 1 path entries using 52 bytes of memory Private-vlan primary Vlan 10 Neighbor 5.5.5.5 ebgp-multihop 3 128 Index 100 i CASE4 : Match ip address 1 300 {100,200}, (aggregated by 300 3.3.3.3) [Case] ​​routing flipping description ? STP and RSTP port comparison: R3 associates the route-map with the redistribution of the direct route 3.3.3.3/32 , 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. Router bgp 345 10.1.13.3 OSPF redistributes into BGP Route-map WT1 permit 20 match ip address prefix-list 2 set weight 100 On R4 , there are also redundant links to 100.0.1.0 and 2.0. Both R3 and R5 can reach the two network segments, and finally R4 selects R3 as the next hop to the two network segments. Because in the BGP routing principle, the route preference decision is compared to the BGP routerID , and the RouterID of R3 is smaller than R5 , so R4 is preferably R3 . Prefix list is much more controllable than access list, supports incremental modification, and is more flexible : ccnp Sw(config-vlan)#private-vlan association 201,202 The route works, but it is basically not used now, because the uncertainty is too strong) Use the match command to match a specific packet or route, and set to modify the packet or route related attributes. Ip prefix-list 1 seq 5 permit 100.0.1.0/24 ip prefix-list 2 seq 5 permit 100.0.2.0/24 route-map test permit 10 RIP update source problem Of course, you can also associate the route-map after re-issuing the command and set the tag in the route-map . Related points 51 Neighbor 10.1.25.5 remote-as 345 no auto-summary Corresponding hwidb fast_if_number 4 Corresponding hwidb firstsw->if_number 4 BGP policy accounting on input is enabled. Note change, replace-as keywords allow R2 to secAS of EBGP when sending routing neighbors, with local-as201 replace real AS200 so replace-as the role of keywords is: Replace with local AS AS Real in the Updates at The EBGP , translate: when the router secondaryAS the EBGP send updated neighbor, with secondaryAS alternative number Pri aS number. FastEthernet1/0 Network 100.0.1.0 mask 255.255.255.0 Ip arp inspection validate { [dst-mac] [ip] [src-mac] } 16 bits Public Timer bgp 0 0 neighbor never goes down In this experiment, we define AS345 as a federated AS , R3 , and R4 as member ASs , using 64512 as the AS number, R5 as a member AS , and 64513 as the AS number. AAAA03 SNAP (fixed value) ? Under normal circumstances, the data is preferred to go ip next-hop , that is, go ISP2 Convergence comparison between 802.1D and RSTP Switchport r >i1.1.1.0/24 Ip route 100.1.0.0 255.255.0.0 null0 RC and RA are separated by RB . In this case, EBGP runs through a non- BGP router by using the configurable " multi-hop EBGP" feature . In other words, RB can not support BGP , and the configuration is as follows ( RA ) If the MED attribute of a route is lost,ccnp route 300-101 study guide, the default setting is to set the MED to 0. However, if this command is configured, if the route with no MED value is received , the MED of the route is set to the maximum value of 4294, 9672, 95. For ISL packages, MTU=1548 ( explained below ) Version The default violation is shutdown . If it is protect , then the penalty will be gentle, for illegal data frames (such as the source of the data frame) Match ip address pref 1 set local-preference 200 RIPng for IPv6 BGP PA can measure or traffic statistics on IP traffic sent by BGP peers. For R2 , it is now in its own process 1 , while learning the route of this OE2 from R1 and R3 , how will it choose? Review Revision record RIP is re-released into OSPF The PC has obtained the address and viewed dhcp snooping bingding databsae on SW1 : description None None 10 The connection is established in advance and the data is transmitted, and the reliability of the data is guaranteed during the transmission. Ip summary-address rip xxxx yyyy // Note that this summary does not support CIDR supernet . Compare by default from top to bottom Topology change mechanism Set ip next-hop verify-availability 10.2.2.2 20 track 2 10.0.0.0/24 is subnetted, 1 subnets Add all ID . match. Such an approach will match community included 100: 11 routes. Match ip address 2 set metric 3 switchport trunk encapsulation dot1q switchport mode trunk *> 100.0.1.0/24 ...... R4 and R2 , we look R2 , R2 moment from R4 has learned this RIP routes, if it from the R3 also learn the route and of the route metric is smaller, then, R2 will preferably from R3 this Routes , so that R1 , R2 , and R3 form a routing loop. VTP pruning Route tag: A tag that distinguishes between internal routing protocol routes and external routing protocol routes. As shown above, the R1 deployment, R1 use heavy publishing directly connected with the introduction of the three external routes, then out distribution lists direction only Classification of path attributes: The configuration of R3 is similar. // match AS ( 100,1 ) and ( 200,1 ) NEXT_HOP to 10.1.123.2 , then if C is not on the router to the IP of PVC , will be a problem, so this should be taken into account. When a violation occurs, the interface enters the err-disable state. Configuration example: Neighbor 10.1.23.3 local-as 201 no-prepend 100 i 100 i Neighbor 10.1.23.2 route-map setCommu in Hello time root bridge sends configuration BPDU default interval 2 is S Root path cost Can only be passed between IBGP peers (unless a policy is made, the LP value will not be lost between IBGP neighbors within the AS ), not in EBGP No off default route above configuration, adding a destined 13.0 network routing next hop is R3 , the PC to 13.0 data network switch to R3 proof ip default next-hop priority routing detail below, above Default route. PS : When the same router has two static routes to the same destination, the outbound interface and the next hop are used respectively. The two routes are load balanced (because the AD value and the metric value are equal). The static route configured by the outbound interface is imported into the routing table as a directly connected network. For details, see the static routing part of this document.
