OSPF ROUTER TYPES
OSPF routers management the visitors that goes traverses throughout the realm boundary. The OSPF routers are categorized primarily based on the operate they carry out within the routing area.
There are 4 several types of OSPF routers:
Inside Router –
This can be a router that has all of its interfaces in the identical space. All inner routers in an space have similar LSDBs.
Spine Router –
This can be a router which resides in spine space. The spine space is about to space 0.
Space Border Router (ABR) –
This can be a router that has interfaces hooked up to 2 or extra areas. It might probably route between areas. ABRs are exit factors for the realm, which signifies that routing data destined for an additional space can get there solely by way of the ABR of the native space. ABRs might be configured to summarize the routing data from the LSDBs of their hooked up areas. ABRs distribute the routing data into the spine. In a multi-area community, an space can have a number of ABRs.
Autonomous System Boundary Router (ASBR) –
This can be a router that has a minimum of one interface hooked up to exterior community (different autonomous system), corresponding to a non-OSPF community. An ASBR can import non-OSPF community data to the OSPF community utilizing route redistribution.
Notable is {that a} router might be performing 2 features. For instance, if a router connects to space 0 and space 1, and as well as, maintains routing data for exterior community, will probably be referred to as a couple of router kind specifically –
- a spine router
- an ABR and
- an ASBR.
