Local-as A non-reflector router can participate in IBGP full interconnection or as a reflector client. Knowledge review Clear ip bgp {neighbor-address} soft in/out specifies a specific neighbor, it is recommended ? SW1 and SW2 are configured as VTP mode client ; SW3 is configured as VTP mode Server 100 i Cause: After the ARP Request is sent , the ARP Reply is prepared for a large number of reasons: scanning on the same network segment (host), scanning across network segments (network device) Switch(config-if)# ip address 192.168.10.254 255.255.255.0 Switch(config-if)# no shutdown FastEthernet0/0 Access-list 1 permit 11.11.11.0 Extended ACL The buddy first introduced the above network environment. This Nima is a fairly classic case. OR1 and OR2 are the egress routers of the network, which are respectively connected to the egress lines of Netcom and telecommunications. PAT is implemented on both egress routers , so that intranet users can access the extranet. In addition to OR1 , About IP Routing Report routing information.

After receiving the data frame, the MAC sublayer of B submits to the LLC sublayer, and the LLC sublayer determines, according to the DSAP field, the connection to which the data frame belongs. Focus on the configuration of GW : * i For the next hop and route tag, see Volume I, page 189 . 4 Virtual-PPP Virtual PPP interface After receiving the BPDU sent by SW3, SW2 stops sending its own BPDU.

R2#sh ip route Network On CISCO IOS , interface x interface mode: Aa:nn additive internet local-AS Router bgp 200 On a specific interface, if no BPDUs are received for three consecutive cycles (or max-age timeout), the STP data on the interface will age rapidly. As a result, the BPDUs are somewhat similar to the keep-alive mechanism between switches . This fast aging mechanism helps to respond quickly to topology changes. *> 100.0.1.0/24 Activate the portfast feature for a specific interface Statically configure a dhcp snooping bingding dabase entry. The command is configured in privileged mode. Vlan 10 After the MAC sublayer of A is added to the MAC address and the LENGTH field, it is sent to the data link. Isis Inject-map to use the route-map in 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 ; basic concept The election of the Root Bridge will not be said. Paths: (1 available, best #1, table Default-IP-Routing-Table) Not advertised to any peer Address-family ipv4 unicast Between R1 and R2 , the original R3 and R4 are updated through a multi-access network, and BGP is run .

If there is a tag , compare the VLAN tag of the frame with the PVID of the port . If the two are consistent, proceed to the next step; otherwise, discard the frame. Ip community-list example 1 : Interface vlan 10 Layer 2 switching This strategy, we can also do on R3 , but the implementation direction of the strategy is in . Migrate to the Established state if you receive a keepalive message from the other party !! GW has no other configuration about routing 345 ; R3 has a federated IBGP neighbor R4 . The configuration of R3 is as follows: Ip dhcp relay information trusted Match metric matches the route with the specified metric. match route-type matches the specified type of route match community matches the BGP community. The RID is the largest IP address on the router and tends to be assigned to the loopback address. It can also be set manually by the bgp router-id command. If a path contains an RR attribute, the route generator ID ( originator ) will replace the RID in the optimal path selection process. Router bgp 300 None When a local BGP route is advertised to an IBGP peer , the MED value must be carried . Matchlog keyword in this command and the log keyword in the permit or deny ARP access-list The following priorities are reduced in order: default-originate (for each neighbor configuration), default-information-originate (for each address cluster configuration), network , redistribute , aggregate-address 10.1.34.3 from 10.1.34.3 (3.3.3.3) End deny any To 100 end of the AS_PATH , which is the route originated in 100AS route Async Async interface The TAG field ( 32bits ) is only present in the external LSA . R1 RIPv1 Often used with the portfast feature on the interface for connecting to the host The process learns the external route, so the update source here is R2 . Network We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows The dst-mac detects the received destination ARP packet. The destination MAC address of the Ethernet frame header is the same as the target MAC address in the ARP body . This check is for ARP response . When this option is enabled , ARP packets are discarded if the two MAC addresses are inconsistent. S uppercase S , stale , indicating expired routes Redis static route-map test *>i * i100.0.1.0/24 Note the access-list 1 method. The result of the experiment is that acl must match the IP and mask of the interface , for example, if written as permit 1.1.1.0 R1 , R2 , and R6 advertise the routes of their respective ASs through EBGP . In AS345 , these routes are re-advertised into OSPF , and then advertised back to BGP on the other two routers , and then advertised to their EBGP peers . . 192.168.123.2 as the next hop better, then R2 subsequent packets sent to R2 . NEXT_HOP on NMBA network Portfast *Mar 4 07:02:23.473: DHCPD: inconsistent relay information. Hostname R1 interface s0/0 Track 2 rtr 2 reachability Each update message describes only a single BGP route. This is because the BGP path attribute can only describe a single route. [Note] If the interface is passive , but at the same time the network interface in the routing process, the interface will not attempt to send updates or establish neighbor relationships, but the network segment where it is located will still be declared into the routing process. 100 Related commands : Route summary 23 Y Routing strategy needs (reliability, redundancy, offloading model,ccnp route download, etc.) Use decimal.

After deploying loopguard : CAM and TCAM 159 220 , 91 70 CCNP ROUTE contains all the contents of the book 2 The distribution list is deployed in a link state routing protocol such as OSPF . If the out direction is to be used, it can only be used in such a situation. Router bgp 1234 Penalty value: 1000 per swing 3.3.3.3 Configure native VTP mode Must be a zero field. Establish IBGP full interconnection and close the synchronization mechanism. This method is basically used at present. But this method has a flaw, that is, if IBGP Router bgp 345 Set extcommunity cost pre-bestpath 1 10 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: [Experiment 1 ] There is a main class route; there is a default route, and the main class route is taken. First, let's get a glimpse of route-map . Looking at the figure above, we redistribute OSPF routes into RIP on R2 . As mentioned above, when re-publishing, you can use the metric keyword to set the metric after the route is re-advertised into RIP . Set to 1 here . The immediate result is that all OSPF routes injected into RIP have a metric of 1 . So what if I want to make some flexibility adjustments? For example, I hope that after the route is injected into RIP , the metric of the 192.168.1.0 route is 1 and the metric of 2.0 is 2 . Traditional redistribution is impossible.
