Other configuration commands .* Let 's take a look at the features of BackboneFast : 100 i Set community no-advertise route-map test permit 20 http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sga/configuration/guide/pvlans.html 2.2.2.0 Routing Although the next hop is directed to R1 , it does not use the outbound interface to create routing entries. From the experimental phenomenon, it is not matched by the match . Needless to say, 3.3.3.0 , the associated interface is s0/1 . Port-channel Ethernet Channel of interfaces AS_SEQUENCE exactly the same, except that the list of AS numbers belong to the local Federation AS Router bgp 345 Address Resolution Protocol 5.5.5.5 After PK , there is no doubt that the default route pointing to telecommunications appears in the routing table, and points to the default route of the education network, "wacky" to hide. When the default route to the telecom is invalid, it disappears from the routing table. At this time, the default route to the education network is "floated". If the route to learn a client , it is reflected to all non- client an IBGP neighbors, and in addition to the client all except client The configuration of R4 is as follows: Private-vlan ioslate Outline 100 i *> 172.16.0.0 Switched network management All VLANs In addition: when the spanning tree reconfigures the new root port, other interfaces flood the network with Switchport trunk encapsulation ? switchport mode trukn switchport nonegotiate Private VLAN concept Clear ip bgp * 9.9.12.0 is directly connected, FastEthernet0/0 Ip address 10.1.34.3 255.255.255.0 5.5.5.5 Router bgp 64512 Redistribute rip subnets route-map test Ip arp inspection log-buffer entries number Community number in aa:nn format Add to the existing community Neighbor 10.1.25.5 remote-as 345 Switchport access vlan 100 interface fast0/24 The switch sends data frames according to the discovered outbound interface. After the interface is configured, the interface switches to the err-disable state immediately after receiving the BPDU . After the configuration is complete, use clear ip bgp * soft to reset it softly. R2#show adjacency detail Ip prefix-list 1 permit 11.11.11.0/24 route-map test per 10 Therefore, when the deployment is re-released, this problem needs special attention. As for how to avoid the problem, I will introduce it in the following content. Sw1(config-if-range)#channel-protocol pagp/lacp Sw1(config-if-range)#channel-group 1 mode desirable Router bgp 345 The identifier of the authentication item indicates that the entire routing packet needs to be verified. Sw(config)#vtp transparent Topology change mechanism (delivery) 8 Switch(config-if)# switchport port-security aging static AS_CONFED_SEQUENCE and AS_CONFED_SET Select the route with the smallest neighbor IP address ( the address of the neighbor in the neighbor configuration of BGP , that is, the update source IP of the neighbor ) Assuming the environment is like this, R1 re-releases A route into OSPF , then R2 will learn this OE2 in its own OSPF process 1 . Preferably EBGP route Private-vlan community Vlan 102 --------------- 192.168.10.1 Private VLAN ( PVLAN ) Route-map test permit 10 The link has failed. Can also be understood as the maximum life of this BPDU , the default 20S Origin IGP, metric 0, localpref 100, valid, internal Originator: 1.1.1.1, Cluster list: 4.4.4.4, 3.3.3.3 RIP defines two types of request messages and response messages. 5.5.5.5 Network Router(config-router)# distance AD ip-src wildmask acls Next Hop *> 1.1.1.1/32 10.1.23.2 65 0 12 i 192.1.168.1 3 0003.47d8.c91f 2BB6488E interface-id 21ae5fbb Display has not been loaded into the RIB in the BGP routing, and why not loaded 10.1.23.2 AS number . 2B , but with the network development, . 2B is not enough, so now expanded to 4 Ge B router bgp? You can view (Note: only available in certain IOS supported under version) RFC2082 Sw(config)#vlan 202 R4 on the show ip bgp 172.16.0.0 192.168.1.0 will pass the default route of 0.0.0.0 into RIP , and R2R3 will learn. As an update source, send it to R3 . BGP table version is 1, main routing table version 1 Then all the 172 network segments on R1 and R2 are suppressed. At the same time, since the route-map test only matches the 1.0 and 2.0 network segments (in AS100 ), this summary route, AS_PATH only inherits AS100 , which is 300 100 ; Definition of 1042 . The most commonly used encapsulation format today is the format defined by RFC894 ,ccnp troubleshooting final exam, commonly referred to as Ethernet II or Ethernet DIX . Sw(config-if)#switchport private-vlan host-association 100 202 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. Origin attribute (priority order: IGP > EGP > Incomplete ) Reduce network migration time without disconnecting existing connections, and do not need to change device BGP configuration in large batches Modify the TAG of all external LSAs generated by the ASBR . LocPrf Here to add a sentence, since attention to traffic, we must pay attention to the round trip of traffic, in general, we want 1.1.1.0 access 3.3.3.0 traffic to go ADC , then round-trip traffic generally requires a consistent path. That 3.3.3.0 to 1.1.1.0 data to a CDA , so to further D on the update to the C of 1.1.1.0 route of metric plus 1 jump. The above command only re-advertises OSPF internal routes and E1 routes into BGP. * i The thing we have to do is very simple. These subnets are continuous. It is enough to pick out the first two or three network numbers to calculate: The vlan number supported by ISL is 1-1005 (the default is allowed to be normal), 802.1q is 1-4094 (all normal and extended by default), so mapping is required when passing through the 802.1q and ISL trunks . Router bgp asnumber Private-vlan community Vlan 102 Route-map test permit 10 match ip address 1 3.1 Overview 20 Router ospf 100 RIP also supports tags , but it must be version 2 . Received a Layer 2 frame. Viewed as one logical link Route-map nat4 permit 10 Add the following configuration on R3 : Access-list 2 permit 192.168.3.0 Local origin It can be seen that the AS_CONFED_SEQENCE attribute is used in the federal inner ring (this attribute will not be federated), while the above BGP routing table entry for 11.11.11.0/24, version 2 // in R3 is only 1.1.1.0 route, that distribute-list 1 out here this command, all externally injected into the When the router is in the boot mode and the software is upgraded, the ip routing is also closed, so the command will be used when necessary. Finally: R4#sh ip b *>i100.0.1.0/24 !! On R1 , Fa0/20 port trimmed only vlan 1 and 10 , because this Knowledge review The configuration on R3 is as follows: The frame to which the Native VLAN belongs is not tagged when it passes the trunk . Next Hop It is valid only when the router (or Layer 3 switch) disables the routing function ( no ip routing ); No shutdown exit Route-map The configuration of R1 is as follows: 192.168.12.1 Pay attention to the changes in our experimental environment. The community value carried in 12.12.12.0 is no-export , if we only want to match no-export Ip prefix-list 1 permit 100.0.1.0/24 ip prefix-list 2 permit 100.0.2.0/24 route-map LP permit 10 ...

Switching is the process of mapping layer 2 to layer 3 addresses andforwarding to a destination interface. 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. ( Well-known discretionary ) Name server If the access layer switch is connected to a single link, there is a single point failure of the single link failure. If any aggregation device is down, it will directly cause the downlink access network to hang. The number of addresses. The switch assigns MAC addresses in order If the routes are from EBGP neighbors, it is preferred that the oldest EBGP neighbor came routing, reduce the impact of the roll (this provision mainly EBGP A sends a data frame to B requesting to establish a reliable connection-oriented connection. Ip community-list 11 permit no-export route-map test permit 10 FastEthernet0/0 B 3.3.3.0 [200/0] via 2.2.2.2, 00:03:01 The range is 10 - 1000000 If it is access mode, the vlan must be the same. Other solutions, we will continue to introduce in the following experiments Message Type Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes, as follows: 120 Offset-list offset list 78 100 If there are routes with the same prefix as follows (the default is sorted in reverse order of route acceptance order) Two routes, on R2 we introduce these two routes using re-release : RIP-1 compatibility RIPv2 sends updates in the form of broadcasts, enabling V1 to receive There are 2 forwarders (1 active) R2#sh ip route Ip route 172.16.1.0 255.255.255.224 192.168.12.1 B is RR , C and D are clients , BCD constitutes a route reflection cluster; a BGP route is advertised from C. When a BGP router sends a route update to its EBGP neighbor, it cannot carry the LP attribute. The LP value of the EBGP route received by the other party is null (even the LP field is there), but it will assign a default to this route locally. Value, that is Switchport mode access switchport port-security For the next hop and route tag, see Volume I, page 189 . *> 172.16.0.0 The configuration of R4 is as follows: The TAG value is set when the originating ASBR generates an external LSA . If the external LSA is re-advertised to other OSPF autonomous systems, the TAG value is carried by default. At this time, on R4 , only 1.1.1.0/24 and 192.168.13.0/24 can be learned. Spanning tree is used to solve this problem Note that, EIGRP the metric is a mixed type, metric. 1 100000 100 255 1500 Parameters specified here, from left to right is the bandwidth, delay, load, reliability, the MTU . It can be flexibly set according to actual needs. After the above configuration is completed, R2 will be in the routing table. Data forwarding mode 13 Netflow switching Technical background 40 The message contains: OpenConfirm Neighbor 10.1.23.3 local-as 201 no-prepend replace-as Neighbor authentication Then in each sequence, we can define two elements for policy deployment: matching conditions, performing actions . You can define multiple conditions, and when the conditions are matched, they will perform the relevant actions specified by the set . Slightly mention here, the set statement is not necessary, for example, if the route-map is only to match the traffic of interest, then there may be only a match statement and no set statement.
