!! Note the difference between the above two commands Example 3 of ip community-list (strictly matching community ): Next Hop \ Distribute-list 62 Example 2 : Route-map usage scenario Working Mechanism Penalize mode shutdown (enter err-disable state) while sending an SNMP trap 14 The configuration of R2 is as follows: RFC1771 A Border Gateway Protocol 4 R1 , R2 , and R3 run RIP and only announce the direct link between the three. In R1 the ip default-network 172.16.0.0 PVLAN configuration example The default load balancing method is round-robin R1(config-router)#redistribute rip subnets tag ? There are 2 forwarders (1 active) METRIC 0 ,ccnp switch by david hucaby, regarded as infinity Neighbor 10.1.12.2 prefix-list 11 out !! Take the default route Although RIP is running between R1 and R2 , the routes of 1.1.1.0 and 2.2.2.0 are updated with each other , but since R1 is from RIP and his OR2 , SW1 , and SW2 run OSPF , and OR2 acts as the egress router of the telecommunications, injecting a default route into the OSPF domain. OR1 will be local At this time, he himself will still forward if he receives the data packet to 3.0.0.0 , but will not forward to other rips. Now, we have to go through the calculations to get a summary of the segments that are just "inclusive". Invalid timer RSTP is designed so that we don't have to rely on the adjustment timer and can make the interface safely transition to the forwarding state. To achieve fast convergence on the interface, RSTP introduces some new concepts: LocPrf Let us look at the above example. In a typical education park network, we often have more than two external network export routes, assuming one for telecommunications and one for education network. Then we generally add a default route to the egress router, pointing to the next hop address of the telecom, in order to allow intranet users to access Internet resources through telecommunication lines . However, if the telecommunications export fails? We can add a default route to the router.
