And SW3 on the same case Completed in the logical interface Canonical Format Indicator , which is 1 bit long, indicates whether the MAC address is a classic format. Complete basic configuration 2 The routing protocols that support TAG are: RIPv2 , EIGRP , OSPF , ISIS , BGP ------------------ 00:B0:64:04:09:99 Match length matches according to the third layer length of the packet Matching 100 , 101 , 102 , 103 , 104 , 109 which AS_PATH Ip dhcp snooping trust Trunk overview 100 i VTP mode 128 Bytes * Available routes (next-hop reachable ) Route-map test permit/deny 20 Ip dhcp snooping vlan 10 Network 100.0.2.0 mask 255.255.255.0 neighbor 10.1.13.3 route-map test out The experiment is completed here, we set MARK , then we will analyze the impact of various attributes on the routing. AAAA03 SNAP (fixed value) 200 i Routing Information Protocol (RIP) Corresponding hwidb fast_if_number 4 Corresponding hwidb firstsw->if_number 4 BGP policy accounting on input is enabled. On the untrust interface, create a security entry by manually configuring ARP ACLs on B. Of course, you can isolate the two switches in three layers, for example, add a router. ! Vlan range MTU problem Neighbor 10.1.13.3 remote-as 345 Each cluster contains a reflector and its client First, in order to avoid the suboptimal path problem, we use the distribution list in the in direction on R2 and R3 to filter out 1.1.1.0 . The range of TAG values ​​in the external LSA Circuit-ID type 100 i Switch(config-if)# switchport nonegotiate Next is the re-release of EIGRP to OSPF : After completing the configuration, R2 show ip route Set default interface specifies how to send such a packet Local origin Vlan 10 Private-vlan ioslate Summarizing on R3 suppresses all details, but if you only want to release partial details for a particular neighbor, you can use unsuppress-map Exact match The src-mac detects the received ARP packet. The source MAC address of the Ethernet pillow is the same as the sender MAC address in the ARP body . This verification action is performed in both the ARP request and the response message. A BGP neighbor has an impact only on the router. It can be understood as a weight value. The larger the priority, the higher. The value is in the range 0-65535 . Configure the secure address of each interface ( Secure MAC Address ) So if we use a solution that re-releases static summary routes: Interface loopback0 Difficult to resolve When the RR sends a route update to an EBGP neighbor, it will be aware of the existing CLUSTER_LIST attribute. Router bgp 345 First select root , the SW1 with the smallest MAC address of the switch wins and becomes root. Route-map PBR permit 20 match ip address 2 Ip address 10.1.25.2 255.255.255.0 The beginning of a string Access-list 1 permit 1.1.1.0 protocol Represents the upper layer protocol ( BPDU ), which is always 0. After 10.1.31.0 is passed to R2 , since R2 takes the mask of the receiving interface and finds that 10.1.31.0 has a position of 1 in the host part , the subnet is stored in the routing table and treated as a host route. : 10.1.31.0/32 Next Hop Id 15 10.1.25.2 Local Subopt : sub-option number, if it is circuit ID , the value is 1 , and the remote ID is 2 Match interface : To distribute any routes that have their next hop out one of the interfaces specified, use the match interface command in route-map configuration mode . The understanding is that the match interface matches the next hop out interface is the route of this interface. entry 300 Precautions: Match ad , abcd , aaabcd, etc. 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 ). For example,ccnp switch tshoot, if a route is flipped, the penalty value is 1000. In this case, there is a half-life ( 15 minutes). After 15 minutes (if the route is not flipped again), the penalty value is reduced to half 500 , and after 15 minutes, it becomes 250. At this time, if the route has another jitter, the penalty value is increased by 1000 and becomes 1250. Before this, the route is used normally. If they shake once, it becomes 2250 , exceeding the threshold 2000 , this route will be suppressed, nor not updated. After 15 minutes, if it is no longer flipped, it is reduced to half 1125 (but still suppressed), so it goes through several half-lives until it is reduced to 750 (re-use limit) and the route is enabled again.
