In OSPF, Link-State information, in other words, Routing information is exchanged between routers. This exchange is done with LSAs (Link State Advertisements). There are eleven different OSPF LSA types and each of them has a special purpose. Some of the OSPF LSA types are the main LSA ...
Type3 --> Sum-Net : 只有ABR可以产生,表示OSPF区域间的路由。只在区域内传输 汇总单个区域的LSA通告给其它区域的路由器,在整个OSPF的AS中泛洪。 Type4 --> Sum-Asbr :与ASBR在同一个区域的ABR产生的,表示ASBR的名字;只在区域内传输 将1类型和5类型关联起来,找出实际走的路径(就像主机要找外面的主机,要...
Backbone Area: It is also known as area0 or area 0.0.0.0; it forms the very core of an OSPF network, and all other areas of the network are connected to the backbone area. It is responsible for distributing routing information between areas that are not backbone area types. Stub Area: ...
OSPF(Open Shortest Path First)是一种用于路由的链路状态协议,它通过在网络中分发路由信息来确定最佳路径。在OSPF中,LSA(Link State Advertisement)用于表示路由器之间的链路状态信息。 在OSPF中,有多种LSA类型用于不同的目的。其中,最常见的LSA类型包括Router LSA、Network LSA、Summary LSA和ASBR Summary LSA。每种...

OSPF is designed for scalability, so some LSAs are not flooded out on all interfaces, but only on those that belong to the appropriate area The LSA types defined in OSPF are as follows: Type 1 - Router LSA - the router announces its presence and lists the links to other routers or ...

So,you’ve read my guide to the new link-state advertisement types in OSPFv3. (If you haven’t, read it now!) Well, now you know the theory, how about we get hands-on with a little bit of practice? Okay, fine, you’ve twisted my arm: we’ll do it. Stop twisting my arm now...
Demystifying OSPFv3 LSA Types Basic configuration of all routers: R1: ipv6 unicast-routing ! interface FastEthernet0/0 ipv6 address 2012:12::1/64 ipv6 enable ospfv3 1 ipv6 area 0 no shut ! router ospfv3 1 ! address-family ipv6 unicast router-id
so if you have an additional rtr that is directly connected via serial as such then no DR/ DR will it exit between RTR1 and RTR6 - you see a rtr can have various ospf network types running at the same time so even though rtr 1 is DR on one interface it can be a BDR/DRother or...
