每个单独的LSA类型在下面的Table 15中进行了简要描述。 The LS type field dictates the format and function of the LSA. LSAs of different types have different names (e.g., router-LSAs or network-LSAs). All LSA types defined by this memo, except the AS-external-LSAs (LS type = 5), are f...
https://networklessons.com/ospf/ospf-lsa-types-explained/ Especially this part: "R2 is going to create a Type 3 summary LSA and flood it into area 0. This LSA will flood into all the other areas of our OSPF network. This way all the routers in other areas will know about the prefixe...
The main thing that sets this course apart isthe simplicity in which everything is explained an illustrated. You will be hard pressed to find better explanations of all the various OSPF concepts above. 此课程面向哪些人: Anyone looking for a practical illustration of OSPF for the modern era ...
OSPF LSA Types and LSA Flooding Explained OSPF Area Types and Concept Explained OSPF Hello Protocol and Packets Explained OSPF RID (Router ID) Explained OSPF Neighborship Condition and Requirement How OSPF Routers Build Adjacency Explained Shortest Path First (SPF) Algorithm Explained OSPF Single-Area ...
OSPF uses areas to limit the routing information routers share. By default, it keeps all routers in area 0. If required, you can create additional areas. If you use more than one area, you must connect at least one router from each area to area 0. That router is known asABR (Area ...
New LSA types are created to carry IPv6 addresses and prefixes, and the protocol runs on an individual link basis rather than on an individual IP-subnet basis. OSPF typically requires coordination among many internal routers: Area Border Routers (ABRs), which are routers attached...
Each LSA also has a type field; the different types of OSPF LSAs are listed below in Table 9. OSPF routing packets (with the exception of Hellos) are sent only over adjacencies. This means that all OSPF protocol packets travel a single IP hop, except those that are sent over virtual ...
New LSA types are created to carry IPv6 addresses and prefixes, and the protocol runs on an individual link basis rather than on an individual IP-subnet basis. OSPF typically requires coordination among many internal routers: Area Border Routers (ABRs), which are ro...
As been explained by Dmnceil above it's the ASBR that informs the ABR using the Type 1 LSA that it is an ASBR. Based on the bits set in the Type 1 LSA - it will instruct the ABR whether or not to translate anything. So in the NSSA-area the ASBR sets the bits on the Type 1...
Reading the RFC 2328 it says that regarding the LSA type 1 for p2p, it generates the Type 1 link as the p2p itself, plus the Type 3 stub network with the Link ID been the network address and the Data Link been the network mask, as you already explained very well. But, there is ...
