3.3.3.3 Distance 100 192.168.12.1 0.0.0.0 1 ...... ------------------ 00:B0:64:04:09:99 Local origin Again rule 11 , it seems to take effect, but this time the R3 of BGP routerID than reform R4 large, found R5 Still preferably R4 , because "If a path contains RR properties, producer ID to select the optimal path during Instead of RID ” 802.3 uses the length field, but the Ethernet frame uses the type field to identify the protocol at the network layer. In an Ethernet II frame, a two-byte type field is used to identify the higher layer protocol contained in the data field, that is, this field tells the receiving device how to interpret the data field. ARP ACL and relative priority of DHCP snooping database entries 32 bits Ip as-path access-list 1 permit .* router bgp 300 Default Port-Security configuration In general, a Layer 3 switch contains two types of ports: Layer 2 interface L2 and Layer 3 interface L3. If the topology is normal, SW3 has an interface that is BLOCK . This interface will not send BPDUs . Address-family ipv4 unicast Each router running RIP manages a routing database that contains routing entries to all reachable destinations on the network. These routing entries contain the following information: Router(config)# router eigrp 100 13 The DA 40bit multicast address is used to indicate that this FRAME is an ISL . 3.3.3.3 In this way, whether the method of re-publishing the static summary route or the method of distributing the list filtering route can ensure that the network is not interrupted in the event of a network failure, as follows: In a route-map statement, if there is no match statement, match all After this time has elapsed, the route entry will become 16 hops, marking the unreachable route possibly down . Gateway of last resort is not set Ip dhcp snooping vlan 10 Interface fast0/1 R2 RIPv2 If R1 starts auto-summary and introduces 1.1.1.0/24 in the way of re-distribution direct connection , the subnet will be automatically summarized to R2. IP routing troubleshootingThe MAC address pool of the CISCO CATALYST switch can hold up to 1024 addresses. The model of the switch determines the number of available MAC addresses . Not all Catalyst switches can support such multiple MAC addresses. ? LoopGuard Configuration example ? Each routing table entry must include at least the following three items: Native vlan Router bgp 100 Sw(config-vlan)#private-vlan community Router bgp 64512 <0-4294967295> 32-bit tag value Access-list 1 permit 192.168.1.0 0.0.0.255 Internal 0 packets, 0 bytes 1.1.1.1 [Experiment 2 ] There are subnet routes (match); there are default routes, subnet routes basic concept To summarize on R3 , use aggregate-address summary-only as-set , then the BGP table on R3 : Authentication (16 octets) Ip route 2.2.2.0 255.255.255.0 192.168.123.2 If there is no tag , mark the PVID of the Access port and proceed to the next step. Weight PVST+ If BGP routes are passed from EBGP peers Then first mark the route prefix of 30.30.30.0/24 on R2 , use the community tag, and configure a route-map at the same time. Used to limit the time that the route staying in the routing table has not been updated. When no port-secuirty mac-address sticiky is typed at this time , all sticky secure address entries become dynamic secure address entries ( SecureDynamic ) Default behavior: source IP address pair ( src-dst-ip ) 1 Router bgp 345 As we R3 on the RIP routes injected into OSPF marked the Tag 1111 , then the next It is recognized that the attribute must be followed to describe the next hop router to the destination. Neighbor 10.1.13.3 remote-as 345 neighbor 10.1.13.3 route-map test out no auto-summary Select interface mode according to specific protocol Configure channel-group on the interface.

The access layer switch uses a dual link to connect to two aggregation devices to form a Layer 2 environment with physical link redundancy, which solves the problem of single link failure. CDMA-Ix CDMA Ix interface After receiving the BPDU packet, the interface will immediately switch to the err-disable state. 0100.e01e.6012.89 R4#sh ip b e Then observe the BGP table on R4 : Sw1(config-if)#ip address 172.16.10.1 255.255.255.0 Sw1(config-if)#no shu It is valid only when the router (or Layer 3 switch) disables the routing function ( no ip routing ); Complete the basic interface IP configuration . Add the following configuration on R2 : Except none or: Use the match command to match a specific packet or route, and set to modify the packet or route related attributes. If both neighbor 1.1.1.1 weight and neighbor 1.1.1.1 filter-list 1 weight xxx are used , the latter is preferred 2 : RIP-2 . If the number exceeds xx , disconnect the BGP connection with the neighbor and reconnect after 2 minutes. The configuration of the DHCP server is a general configuration and will not be described here.

At the same time, it is also possible to delve into the routing problem. For example, if R2 is localized to the 1.1.1.0 static route and is configured as the default route, we will find that the BGP connection can still be established, because R2 is the passive of the BGP connection in this example. who, R1 have specific routes to initiate connection. However, if the static static route from R1 to 2.2.2.0 is changed to the default, then it will not work, and R1 will consider " no route to peer ".
