ccnp switch chapter 9 answers

In the above figure, R1 and R3 will update routes 1.1.1.0 and 11.11.11.0 to R2 . Of course, by default, R2 is definitely the preferred EIGRP. 8 Incomplete All clients in the route reflection cluster should establish IBGP connections with and only with all RRs in the cluster. ! Track 1 rtr 1 reachability Network Neighbor RC-ip remote-as 100 i After completing the configuration, R2 show ip route Route 1 : AS_PATH : 500 // 100: 200 indicates that this is for the AS200 's *>i100.0.2.0/24 The configuration of R2 is as follows: PVST+ Bgp fast-external-fallover When no BPDU is received for a period of time and the lifetime reaches MAX age , the bridge considers that the port is connected. Match the previous character 0 or more times Let's look at the picture and deploy a two-way re-release on R2 and R3 . You can further configure this logical etherchannel interface. Data ( DATA ) Show ip bgp Ip route 172.16.0.0 255.255.0.0 192.168.23.3 90 ?

The above process is the result of testing on the CISCO device (server).

All physical interfaces of the switch are Layer 2 interfaces by default, which is switchport . ^$ Match interface matches the route with the next outgoing interface as one of the specified interfaces. Experimental verification Y Show ip route dhcp Displays routes added to the routing table by DHCP This strategy, we can also do on R3 , but the implementation direction of the strategy is in . TCP connection establishment was successful, starts sending Open package, Open packet carries establish parameter negotiation peer. Port role: Ip address 10.1.45.5 255.255.255.0 Metric problems 44 Internal EIGRP Switches, we are in VLAN configuration on the interface IP address, VLAN interfaces we called SVI switched virtual interface, it is with VLAN a corresponding logical, and virtual interfaces. A Layer 2 switch can only assign an IP address to a VLAN interface . Router bgp 345 Double-point bidirectional routing re-release 91 METRIC OSPF can let R3 learn 1.0/24 and 2.0/24 routes. Note that the as-path access-list is also implicitly rejecting all by default. Bgp bestpath as-path ignore Select 10.1.25.2 as the next hop to the two network segments and load the route into the routing table. So why does R5 choose R2 ? Show ip bgp injected-path to display Switchport access vlan 10 If there are multiple routes from the same neighboring AS and multiple paths are available through Maximum-paths , all routes with the same cost are added to Loc-RIB. Revoked route Route filtering or execution strategy during redistribution Match interface s 0/0 Instead of choosing R3 ? This is determined according to the routing principle of BGP (see the BGP document of Red Tea Three Cups Zhu SIR ). Here, the final impact of routing is such a rule "preferred routing from EBGP neighbors (relative to IBGP neighbors) "), R2 is the EBGP neighbor of R5 , so it is preferred. So if we use a solution that re-releases static summary routes: RIPv2 manual summary *> 100.0.1.0/24 technical background This command can be used in the following ways: The next hop of the A segment becomes R4 , which results in a suboptimal path. Also, on R3 , the re-release of process 1 to process 2 fails. Bgp dampening ? Show ip bgp flap The switch configured with Uplinkfast needs to be a stub switch or an access layer switch in the network three-layer structure. It cannot be the root bridge. Sw(config)#vtp transparent If you do the following configuration on R2 : It is valid only when the router (or Layer 3 switch) disables the routing function ( no ip routing ); Neighbor R3 filter-list 2 weight 5000 Set the interface to access mode Therefore, AVG is responsible for distributing virtual MACs , and AVF is responsible for forwarding data. Network 5.5.5.5 0.0.0.0 area 0 100 TCAM is the table that is checked when the routing module or router is used for Layer 3 forwarding. Active: capita ask if the other side can/will Next Hop The disadvantage is that the original Ethernet frame is destroyed and the FCS is recalculated . ISL is the direct encapsulation header and trailer. DOT1q public, ISL private The default is 6 update cycles, which is 180s . The route entry tag when an entry with a larger hop count is received Next-hop , the next-hop is changed to the update source IP of R3 , which is the loopback interface IP. Set ip address prefix-list 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 . BGP table version is 3, local router ID is 3.3.3.3 Root path cost Experiment 3 We look at the above picture, the external detail route 172.16.32.0 – 39.0/24 , and the summary route 32.0/21 are introduced into OSPF by R1 , now 3.3.3.3 The TAG field ( 32bits ) is only present in the external LSA . 3.3.3.3 Just match this AS_PATH of 100 A standard ACL can only match the route prefix and cannot match the prefix length of the route. For example, if you want to fetch the 192.168.1.0/24 route and use access-list 1 permit 192.168.1.0 , the route is matched, but at the same time, 192.168.1.0/25 , /26 ... are also matched because the ACL cannot match the mask, or the prefix length. Furthermore, when using a standard ACL to fetch routes, it is recommended not to add an anti-mask,ccnp switch chapter 9 answers, otherwise the range of matching route entries will be larger and less accurate.
