Interface mode, configure the interface as DAI trusted , the default is untrusted Note that this is just a basic authentication feature, not encryption. Aggregate-address 192.168.0.0 255.255.0.0 attribute-map test // Associate route-map test works on aggregated routes Ip prefix-list ABC seq 5 permit 172.0.0.0/8 200 i Experimental phenomena: Encapsulation protocol Set ip next-hop verify-availability 10.1.1.2 10 track 1 Root received the TCN , sent back a TCN ACK to C . !! The red font part is the number of hops to be increased ? 100 The LSA sends the neighbor to the neighbor, so the local route is filtered, and the neighbor has (because the neighbor has received the LSA ). R2#sh ip b 100.100.100.0 Bgp always-compare-med Match ip address prefix-list 2 router bgp 100 Switch(config)# interface vlan 255 Version At the same time, if 172.16.1.0 and 172.16.2.0 are all DOWNed at this time , the summary route also disappears. S 172.16.3.0/24 [1/0] via 172.16.23.3 0.0.0.255 will not work. Mode 0 ? Access-list 1 permit 192.168.1.0 0.0.0.255 LOCAL-PREFERENCE 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. Ip rip triggered Configure no switchport ( routed port ) Layer 3 interface As a result, there is no problem with route delivery. Look at the above picture, the gray space 172.16.0.0/16 , this network number,ccnp troubleshooting (300-135) cert prep, we call the main class network number , the so-called main class network number, meaning the network number, according to the IP address category to which it belongs , corresponding to The network number obtained after the default subnet mask length. Such as 172.16.0.0 this is a 0 ? 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. The process of processing a VLAN frame by a trunk port is as follows: "Double-point bidirectional" routing re-release is a simple model that can often be used in large networks. For example, in a financial network, if a dynamic routing protocol is run between a secondary line and a branch router, then this model may be involved. The so-called two-point bidirectional refers to a node with two routes re-issued on the boundary of two routing domains, and the direction of re-distribution is bidirectional. For example, in the above figure, the secondary line has two aggregation routers for access to the following outlets or branch routers. Then the two routers are two-point. In addition, in order to make the routes of the entire network reachable, two-way routing re-distribution is deployed on the two routers, that is, OSPF is re-released to RIP , and RIP is also re-released to OSPF. .
