Modify the AD value of EIGRP RIPv1 , v2 Mode Trunk port processing frame process Network 100.0.1.0 mask 255.255.255.0 All VLANs [Start process exchange] Next Hop : 1 DNS , WWW , and SMTP servers belong to the same subnet This attribute may not be supported. Unrecognized BGP processes ignore update messages containing this attribute and are not passed to other BGP neighbors. FastEthernet0/0 Neighbor 4.4.4.4 ebgp-multihop 4 TIMER The simple horizontally separated rule is that the update message sent from an interface does not contain the network contained in the update received from the interface. In other words, the route I received from this interface will not be from this interface. Send it back. 100 ? The IGP routes into BGP when the associated Route-map settings Match ip address 1 Router bgp 345 This experiment mainly verifies that automatic summarization does not occur at the boundary of the main class network: OSPF , but R3 ignores this route (locally configured with a static summary route pointing to null0 ), although the LSA is still passed to R5 , which means that although R5 still has a 1.0.0.0/8 route, the packet After being thrown to R3 , it is finally discarded at R3 , so there is still a problem here. Compatibility Another problem with proxy ARP (from TCP/IP routing technology volume one) Encapsulation Status Set metric-type internal To other neighbors The description of several fields ( ISL header) in the above figure is as follows: Preferred routes sent by EBGP neighbors (relative to IBGP neighbors), preferred federated EBGP routes in federated EBGP and IBGP R3 and R5 both advertise the routes of the same network segment to R4 . If the first eight rules cannot be determined, if R4 is configured: Protocol basis ! ------------------ 00:B0:64:04:09:99 Remote-ID type The interface will not send BPDUs , and will also ignore received BPDUs. If there is an error, enter the OpenConfirm state. 4.3.1 improvements 35 BGP Speaker from IBGP routes learned whether it's advertised to EBGPpeer depends IGP and BGP synchronization to decide 100 STP uses four parts to solve the Layer 2 loop: Use show port-security address to view the security address entries on each port-security interface. Configure the aging time of the security address. Route-map test permit 10 Class and classless route lookup mode 9 // EBGP neighbor The medium to root has the least overhead, so the uplink port is RP . SW3 is different. Since the bandwidth of the interface connected to root is only 10M , the interface connecting SW2 wins as RP . Finally choose DP . I won't go into details. Port-security supports 802.1Q tunnel interface Redistribute ospf 1 Remove VLANs from the current list After aggregate-address 192.168.0.0 255.255.0.0 , R1 can learn summary routing and 2.0 DTP enables trunk negotiation between switches After the route-map is called, the matching action will be executed from the smallest sequence number. If the conditions in the sequence number are matched, the set command is executed . If the conditions do not match, the switch to the next sequence number is continued. Match the action. R4 released the RIP route of 100.1.1.0/24 , which can be learned by both ASBRs . The solution is to configure static summary routes on the two ASBRs : Use RR ? PS : At present, the Ethernet frames we use are basically Ethernet II frames. Once the ORF is deployed , the BGP peers will negotiate the ORF capability in the open message when the BGP peer relationship is established . If the negotiation succeeds, the ORF content is pushed using the route-refresh packet . 0xFFFF The GW configuration is as follows: Network 100.0.1.0 mask 255.255.255.0 *Mar 16 17:09:21.858: DHCPD: relay information option exists, but giaddr is zero. Between R1 and R2 , the original R3 and R4 are updated through a multi-access network, and BGP is run . After SW3 receives this message, it knows that SW2 no longer has vlan10 users, and no longer needs vlan10 traffic, so it will trim vlan10 on its own FA0/22 port : However, we found that R4 did not pass these two routes to R5 , which is because of the effect of IBGP 's horizontal splitting principle. According to the IBGP split horizon principle, a BGP router,ccnp route demo exam, if it learns BGP routes from its IBGP neighbors , will not be able to pass these BGP routes to other IBGP neighbors. The reason for setting this rule is that BGP anti-ring needs to resort to Due to the lack of a feedback mechanism, the interface connecting A to Root from Listening to Forwarding needs to experience a delay of 15*2s . In this case A , B , C the second line on the user traffic problems (since D in better received BPDU after the P1 port block , this time ABC corresponds A root port transitions to the forwarding are in the network before the " buffer zones " ) <100-500> Community list number (expanded) expanded Add an expanded community-list entry During the migration, the router running DUAL AS can establish EBGP with the external AS using both the primary AS and the secondary AS. In BGP , the network command has nothing to do with which interfaces BGP runs. Just inject a local network into BGP . This route is called reliable. Only the route exists in the router's routing table (not B ). It is possible for the network segment in BGP to pass the route entry to the BGP neighbor. It is important to note that the network can only effectively inject non- B routes that exist in the routing table . If I have a local the Loopback , 4.4.4.0/24 and I BGP in Network 4.0.0.
