Optional delivery Set comm-list del delete route-map test permit 20 When both the primary and secondary addresses exist, RIP will use both the primary and secondary addresses as the source to send routing updates. So R1 and R3 will learn the routing update of 2.2.2.0 . But R3 ca n't learn 1.1.1.0 , on the one hand, because R1 sends updates to R3 and is ignored by R3. Router ospf 100 Sent from the root bridge BPDU number of seconds after (this BPDU survived for how long), each through a bridge are minus 1 , so it is essentially the number of hops to reach the root bridge. Two-point two-way route is re-released 10.1.23.0 is directly connected, Serial0/0 Private AS number Access-list 1 permit 10.1.1.0 Set the interface to DTP dynamic negotiation, optional auto or desirable Ip local policy route-map x Network 172.16.11.0 mask 255.255.255.0 The route closest to BGP NEXT_HOP is preferred , and the route is the route with the smallest IGP metric to the next hop router . The AD value of 11.11.11.0/24 is adjusted to be larger than OSPF , for example 130 . So the configuration is as follows: If the network implements IBGP full interconnection ( IBGP neighbor relationship is established between each other ), then synchronization is meaningless and synchronization can be turned off. So today's CISCO IOS turns off synchronization rules by default. BGP routing table entry for 100.0.1.0/24, version 4 ! Therefore, the role of the no-prepend keyword is: Do not prepend local-as to updates from ebgp peers . If you advertise the route to the EBGP neighbor of the primary AS , the secondary AS number is not attached . The secondary VLAN is mapped to the SVI interface of the primary VLAN , allowing for Layer 3 switching of pVLAN ingress traffic. Communicates with all other ports Ip route 172.16.3.0 255.255.255.0 172.16.12.3 Length Ip address 3.3.3.3 255.255.255.0 100 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,ccnp route lab manual 2nd edition pdf, 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 .
