Packets / / Use the federal member AS number to establish BGP The configuration of the DHCP server is a general configuration and will not be described here. The configuration of R3 is as follows: Bgp bestpath as−path ignore This command, if configured, skips this rule EBGP non-equivalent load balancing When both DSAP and SSAP take a specific value of 0xff , the 802.3 frame becomes a Netware-ETHERNET frame to carry NetWare. Interface trust status and network security issues BGP route advertisement Neighbor 1.1.1.1 weight 2000 sets the route sent by the neighbor to 2000 weight (local) The Conditional inject is configured as follows (in BGP routing process mode): The problem that the static route associated with the outgoing interface is re-released. When a BGP route is sent from the group members of the cluster to the RR , RR Router bgp 100 We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows TblVer InQ OutQ Up/Down State/PfxRcd 1.1.1.1 (metric 129) from 4.4.4.4 (4.4.4.4) Next Hop So if we use a solution that re-releases static summary routes: On: channel member without negotiation ( no protocol ) The configuration of R3 is as follows: Network Next Hop Metric LocPrf Weight Path Neighbor management Adjacency table Ip arp inspection vlan {vlan_ID | vlan_range} Note that if you attempt this time SW2 on F0 / 2 interface priority piecemeal, and it is useless, because the port is looking at the sender ID . So if on SW1 , the port priority of F0/2 is reduced. Then on SW2 , F0/2 will win as the root port. Both Connectionless data transfer service with acknowledgment. This is a very typical case. In the above figure, the network environment is like this. Suppose we have two routers, R1 and R2 , connected to the server farm. The server farm uses two three-layer switches to hang the network server. We have planned two subnets for production of 10.1.1.0/24 and office 10.1.2.0/24 . R3 is the access router. R1 , R2 , and R3 run OSPF . We mainly analyze: Ip route 172.16.0.0 255.255.0.0 192.168.23.3 Routing VS.

Layer 2 interface (switchport) : access mode, trunk mode 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 : Vlan 10 Access-list 2 permit 10.1.2.0 route-map cisco permit 10 EGP Ip dhcp snooping The summary of the route is actually done by the operation of the subnet mask. For the following example: Switchport access vlan 100 interface fast0/24 Synthesis example 1 : The LP field is all there, but it will assign a default value to this route locally, which is 100 , and then pass it to its own IBGP. BGP table version is 3, local router ID is 4.4.4.4 IBGP horizontal segmentation BGP routing table entry for 100.100.100.0/24, version 5 Paths: (2 available, best #1,ccnp tshoot number of questions, table Default-IP-Routing-Table) Multipath: eBGP In half-duplex mode, the CSMA/CD access method is adopted . What are the components of CEF : Routing time: The time elapsed since the last time the routing entry was modified. The routing time is reset to 0 each time the routing entry is modified . BGP routing table entry for 100.100.100.0/24, version 2 Paths: (2 available, best #2, table Default-IP-Routing-Table) Flag: 0x820 Must be zero The role of the root bridge is preemptible If R1 R2 is established between EBGP neighbor relationship, because EBGP establish neighbor relations will check direct route, and the default TTL = 1 , and Match ip address prefix-list 11 set community 100:11 200 As you can see, the route carries the atomic-aggregate attribute, which is used to inform the downstream neighbor that this is the route attribute that summarizes the route and loses the detail. At the same time, the aggregator attribute identifies the summary location ( the RouterID of the AS and the summary router ). Priority 120 (configured) 100 This is a feature that is used in large and medium-sized networks to make the configuration "modular". LocPrf 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 . Interface loopback2 Second layer bundling *> 100.0.1.0/24 Mtu 1500 , so it will be fragmented, then on R2 , the two fragments are reorganized. Cisco CEF is the most efficient three-layer protocol. CEF uses a hardware-based platform . It not only stores data in the system buffer, but also " prestores " the entire routing table, topology table , and all next hop addresses and MAC addresses , as long as the routing table, The entries in the topology table , regardless of whether there is a data request sent to its destination address , will be pre-read in advance , pre-set the cache . Thus , when there is a new data request to send , the CPU is not required to query the destination interface , destination MAC Address and other information , but read directly from the cache , so the forwarding speed is greatly improved .
