how hard is the ccnp route exam

WWW and SMTP belong to the Isalated VLAN , so they cannot access each other; WWW and SMTP servers can only communicate with the promiscuous port, that is, with the router. OSPF Flag: 0x860 In a real-world environment, an IP address is generally used to indicate the object of communication, and the function of ARP is to " resolve " the IP to the corresponding MAC address. AS_SEQ type is {100 , 200} in this segment is AS_SET type. So AS_SEQ the AS_PATH used to identify the origin of this summary route, it is ordered AS list, in addition AS_SET this AS_PATH type used to identify the details of pre-aggregated VTP Traps Generation 201 100 Route metric is 0, traffic share count is 60 Configuring static routes Vlan 10 There can only be one Isolate vlan in a primary VLAN. The SYSID can also be used as an identifier for a VLAN or an MST instance. For example , the system ID extension of VLAN 100 is 100. Vlans allowed and active in management domain 1 Network Layer Reachable Information ( NLRI ) One or more (length, prefix) binary groups used to advertise IP address prefixes and prefix lengths Ip route 0.0.0.0 0.0.0.0 192.168.23.3 Preferably the BGP NEXT_HOP nearest route 201 200 Set metric 1111 BGP , but the BGP routes ( BGP packets) between the BEs can be forwarded through the CD . For the CD , these BGP messages are regarded as normal IP packets and are directly forwarded and not viewed. VLAN isolated from each other, the broadcast can not cross VLAN communication, and therefore a different VLAN devices unable to reach between the general, different VLAN need to communicate with each other between the layer 3 device The VTP protocol sends a VTP advertisement on the trunk link through the multicast address 0100-0CCC-CCCC . And the preferred order is: i > e > ? R2 ignores R1 update sent over, because the "active examination", from R1 sent from the RIP updates and R2 of S0 / 0 Kou not in the same subnet,how hard is the ccnp route exam, so R2 ignored R1 incoming routing updates. At this time, just validate-update-source under the RIP process of R2 . The longest match principle is the default route lookup method for CISCO IOS routers. When the router receives an IP packet, it performs bit-bit bit-by -bit lookup between the destination IP address of the packet and the entry in its local routing table until the longest matching entry is found. This is called the longest match. in principle. Route Control Overview 77 Tunnel Tunnel interface Router(config-router)# passive-interface fast 0/0 Router(config-router)# neighbor 192.168.123.2 If it is access mode, the vlan must be the same. The federated AS number in AS_PATH is used to avoid loops within the federation confidential The TCP connection was not successfully established and the TCP connection was tried repeatedly . Here, because there is an OSPF interval , and OSPF does not know BGP , the BGP attributes will be lost during the re-release process . (for forwarding delay), this TC will last for 35s ( 20+15 ) In fact, the establishment of a BGP neighbor relationship requires only one connection. The configuration shown in the following figure can also establish a BGP connection: Redis static route-map cisco 4.3.3 Certification 36 Protocol overview Route-map WT1 permit 20 match ip address prefix-list 2 set weight 100 Configure this command. When routing, the router only compares all routing entries with the AS_CONFED_SEQ attribute. This command is used for federated routers, while weight and LP have higher priority than MED. Network 10.1.34.0 0.0.0.255 area 0 Corresponding hwidb fast_if_number 4 Corresponding hwidb firstsw->if_number 4 BGP policy accounting on input is enabled. Network consolidation (same protocol or different protocols) Note that the neighbor 1.1.1.1 filter-list x weight yyy command can be used multiple times for a neighbor, that is, set different weights for different routes . But the neighbor 1.1.1.1 filter-list 1 command, in the same neighbor in or out direction, can only be used once, these two commands are very different R4#sh ip b 100.0.1.0 Route-map test permit 10 match ip address 1 Match metric matches the route with the specified metric. match route-type matches the specified type of route match community matches the BGP community. Received a Layer 2 frame. 30.30.30.0/24 Ip default-network 108 Communicates with other members of community and all promiscuous ports ! 100 R4 can learn from R1 and R2 of the 100.0 network routing, and the previous experimental results, we know, without any deployment strategy, R4 preferably RouterID small R3 as destined 100.0 segment BGPpeer , then Can we influence the routing preferences by controlling AS_PATH ? Next, we use route-map to make a policy on R1 , which takes effect on R3 and modifies the AS_PATH path attribute of the 100.0.1.0 route . Eventually, R4 goes to the 1.0 network to go to R2 , and goes to the 2.0 network and still goes to R1 .
