Dampening takes effect only on EBGP routes and invalidates IBGP routes. When using Ip default-network to refer to a network locally, if the network number exists in the routing table, the router will designate the network as the default gateway. ( If MED is empty , it is set to 0) Route-map Overview 55 Below we summarize some of the key points of the router about route lookup: 100 We will ping 1.1.1.2 repeat 1 size 1500 , we will find that R1 directly sends an ICMP packet, no fragmentation, the message is as follows: R1 , R2 running OSPF , R2 learned 1.1.1.0/24 the OSPF routing ( Metric to 65 ) in R2 on the BGP routing process in the network 1.1.1.0 mask 255.255.255.0 Message interaction process Aggregate-address summary address summary-only Reviser Once the portfast port is connected to the device, the interface can bypass the listening and learning states and enter the forwarding state directly .

If the RIP protocol is running in the network , in fact, for A , going to 3.3.3.0/24 can be shared by B and D load. However, in some cases, we hope to data is controlled, for example, we want to 1.1.1.0 Access 3.3.3.0 of the main traffic go B , when B hung up, then switch to the D on. So we simply in D deployment offset-List , in which the A notice 3.3.3.0 routing, increased 1 jump, then this route will be compared to B advertised to A route metric big a jump, A naturally preferably B .
