10.1.13.1 RSTP If the interface is configured as a host interface Beta Redundant RR environment LocPrf On R10 , the route is redistributed into OSPF . R11 learns 8.8.8.0 through OSPF . On R11 , the route is: Advance 100 i The disadvantage is that the original Ethernet frame is destroyed and the FCS is recalculated . ISL is the direct encapsulation header and trailer. DOT1q public, ISL private No synchronization no auto-summary Note that with route-map , the last is implicitly killing any , while the suppress-map is different. RFC1058 The maximum time allowed before a KEEPLIVE or update message must be received . If Holdtime is inconsistent at both ends , both parties accept a smaller time. Experiment 3 Sw(config)#vlan 100 R4#show ip bgp 172.16.0.0 That is, a site address, the MAC address, is reserved at this level to identify the only site on the network. Next Hop Network .* Vlan 10 100.100.100.0 [20/0] via 10.1.23.3, 00:02:57 10.1.12.2 The AS_SEQUENCE attribute will be passed to R7 along with the route 11.11.11.0 , so the packet is captured on R7 . The attribute of AS_CONFED_SEQENCE is not visible in the route of 11.11.11.0 , so the external AS treats the federation as a single AS (outside I don't know the situation inside the federation) 100 i confidential IP address, and then take the destination IP address to look up in its own routing table. After finding the "best match" entry, the packet is forwarded according to the outbound interface or next hop IP indicated by the routing entry . This is the IP route. ( IP routing ) . And each router maintains a routing table locally. End deny any Ip dhcp snooping Therefore, when the route lookup mode of the router is classless or the classless route lookup mode, the default lookup action of the router is the longest match criterion. For example, in the above figure, when R3 receives a packet and goes to 172.16.1.1 , then in fact, 172.16.1.1 is "dropped" in the network of 172.16.1.0/24 and 172.16.0.0/16 ,ccnp r&s tshoot, both seemingly Yes , but 172.16.1.0/24 obviously has a longer match, so the packet is eventually dropped to R1 . Similarly, if there is a data packet going to 172.16.2.1 ? Since the entry of 172.16.2.0/24 is the highest according to the longest match principle, the data is thrown to R2 .
