Neighbor 10.1.13.1 remote-as 100 After deploying Backbone Fast , SW3 will immediately perform a series of steps to recalculate the root port as soon as it receives the suboptimal BPDU sent by SW2 . SW3 will send an RLQ request from the root port to the root bridge. Reference 39 Router bgp 100 ! ! Automatic generation 10.1.13.1 Next is the re-release of EIGRP to OSPF : Redis static route-map cisco Manual bindings are IP addresses that have been manually mapped to the MAC addresses of hosts that are found in the DHCP database. Manual bindings are stored in NVRAM on the DHCP server. Manual ARP packets are detected and released directly. For untrusted interfaces, ARP packet after receiving back checks only legitimate ARP packets can not be released, if the emergence of illegal ARP packets, it will be log , while discarding. STP cost to the root bridge Ip route 0.0.0.0 0.0.0.0 Education Network Next Hop IP 10 Network 100 i 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 The route -map used by exist-map has at least the following two match statements: Aggregate-address 192.168.0.0 255.255.0.0 as-set advertise-map adv CISCO private, the scope of this router is (not passed),ccnp route 300-101 by eng-abeer hosni, this value will not be included in the update message, nor will it be passed to any When LINK1 DOWN is dropped, SW2 will not receive the BPDU from ROOT , so it considers its root and starts to SW3. * i100.0.1.0/24 Detailed rules The maximum survival period in the discard BPDU before the bridge used to store BPDU time default 20S . If consecutive receive 10 th bpdu When 10.1.1.2 is reachable, the track object is true Switch(config)# ip routing Configure static routes by using the associated outbound interface. doing what Experimental verification Run RIPv2 , the default R1 update 1.0.0.0/8 is summarized to R2 , and the automatic summary is closed on R1 , then R2 learns to 1.1.1.0/24 , and since it still starts automatic summarization, the update to R3 is 1.0.0.0. /8 . This time if R2 on ip route 1.1.1.0 255.255.255.0 null0 , then R2 is routed on the table 1.1.1.0 becomes static static routing, and the R2 is no longer to R3 updated RIP 's After bgp confederation iden 345 configuration, for the federated AS , this AS is not what 64512 , but 345 Interface vlan 100 Neighbor 10.1.12.1 remote-as 100 *Mar 1 00:11:47.891: ICMP: echo reply rcvd, src 2.2.2.2, dst 192.168.123.3 So if we use a solution that re-releases static summary routes: Complete the basic interface IP configuration . Add the following configuration on R2 : IBGP neighbor relationship VTP configuration Basic knowledge point Experimental verification ( IBGP equivalent load balancing) When ISP1 is down, the interface of GW connected to ISP1 is DOWN , and the traffic of PC access 100 is automatically switched to ISP2. Remove VLANs from the current list 10.1.13.1 The BGP update is carried by the TCP protocol. The port number used is 179. Because BGP requires TCP , there must be a BGP peer . The DAI is deployed on the switch to ensure that legitimate ARP requests or responses are released and illegal ARP messages are discarded. The main actions of the switch after deploying DAI are as follows: Then on R4 , you can only learn 1.1.1.0 . If you want 11 routes of 100: 11 and no-export two community values are deleted, modified del This community-list to: Network The TAG field ( 32bits ) is only present in the external LSA . Detailed rules Experimental description Aggregate-address summary address summary-only Set ip next-hop verify-availability 10.1.1.2 10 track 1 Snooping can protect against DHCP spoofing. On the other hand, it will get DHCP snooping binding on the switch. Path Neighbor 10.1.13.3 route-map test out After the Uplinkfast feature is activated , the switch automatically adjusts some parameters: Ip rip trigger Port When R5 is updated to EBGP neighbor R2 BGP route 5.5.5.0 , NEXT_HOP =192.168.25.5 , this attribute will always be followed by this BGP route in AS234 . At this time, for R4 and R3 , I don't know how to go to 192.168. 25.5 , so the 5.5.5.0 route cannot be properly loaded into the routing table. One solution is to R2 in the IGP injection route 25.0 This external routes, the other is R2 its IBGP neighbors using the Next-Hop-Self , modify this prefix NEXT_HOP properties.
