Match, and the result is that there is no match, it is directly discarded, regardless of whether there is a valid entry in the DHCP Snooping database . Generally done at the AS boundary, tell yourself the local-pref value from within AS . It is recognized that the attribute must be followed to describe the next hop router to the destination. Match ip address RIP-2 Only Access-list 1 permit 1.1.1.0 Detect the reachability of the next hop, the default is off View command: Show eth 1 summary / show ip route / show ip int brief Local-as Network Local-Preference RIPng for IPv6 Data forwarding mode 13 Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only Vlan range and mapping Tag 1111, type extern 2, forward metric 64 End of a string The frame structure formed by the MAC sublayer is mentioned in the introduction above , including IEEE802.3 frames and ETHERNET_II frames. Different OSPF between two-point two-way process re-release, can also use a static summary route re-issued, respectively, in two ASBR create different static routes summary above, re-publish static summary routes in the corresponding processes. Access-list 1 permit 10.1.1.0 The following uses an example to illustrate the application of SSAP and DSAP . Assuming that Terminal System A and Terminal System B are to use a connection-oriented and reliable data transmission service, the following process occurs: Ip default-network 172.16.3.0 becomes: ip route 172.16.0.0 255.255.0.0 172.16.3.0 SW3 immediately aging the BPDU stored on Fa0/3 , and port Fa0/3 enters the listening state and starts to send BPDUs. Sw(config)#interface fa0/24 SW1(config)# interface vlan 10 The so-called one-arm routing is on the Ethernet port of the router (must be above 100M interface) to carry VLAN traffic, let the router and switch run a trunk , use dot1Q encapsulation, at this time, in order to let the router's Ethernet port support Dot1Q To identify and carry VLAN traffic, you need to divide the subinterface of the physical interface, as shown in the figure above. Designated port: Select a designated port on each segment , which will send the best BPDU on this segment . 10.1.23.3, from 10.1.23.3, 00:07:30 ago 16 bits [Experiment 5 ] There are subnet routes, the subnet route prefix length is different (but both match), and the longest match Interface vlan 100 EBGP non-equivalent load balancing Metric Routing entry for 8.8.8.0/24 LocPrf RSTP has made minor modifications to BPDUs only on an 802.1D basis : 200 Distance vector routing protocol A match to a start, the end of any single character string, such as A0 , a! Etc. Make a summary on R3 , use aggregate-address summary-only as-set , note that the as-set keyword is added. 10.1.25.2 Path Local origin STP uses four parts to solve the Layer 2 loop: Strange phenomenon: In the BGP table of R5 , there are only two routes advertised by R2 , and the 100.0 route from R3 is not passed to R5 via R4 . In other words, we expect that AS345 will have redundancy to 100.0 network. Remaining path (through R1 , R3 associates the route-map with the redistribution of the direct route 3.3.3.3/32 , tag#11 , and the route is passed to R2 . On R2 , the redistribution of RIP to OSPF is deployed. After the external route of 3.3.3.3 is injected into OSPF ,ccnp switch free labs, the tag value is carried by default. When a link needs to carry multiple VLAN information, you need to use trunk to implement IP policy routing is disabled Set ip next-hop ip1 ip2 ip3 , this knowledge point is no problem, right? After the match is live, the packet is first sent to the first next-hop ip address . If the direct connection associated with the ip address is DOWN , then the next next-hop ip address is switched , so next-hop .
