Any time you’re planning to go the BSCI Examination on the way into the coveted Cisco CCNP 메이저사이트 certification, you could be rapidly overwhelmed because http://edition.cnn.com/search/?text=토토사이트 of the sheer degree of BGP and OSPF knowledge it's essential to reveal a mastery of. A single list of facts that some BSCI and CCNP candidates underestimate are definitely the distinctions in between the OSPF router sorts.
An OSPF Interior router has a person rule – it have to have all its interfaces in an individual space. It doesn't imply that space must be Region 0.
An OSPF Backbone router can be a router with at the very least one place during the OSPF spine space, Space 0. A router might be the two an Interior and Spine router if all its interfaces are in Area 0.
A location Border Router has at least a single interface in Place 0 and A further interface inside of a non-spine space. ABRs can also be certainly one of two router sorts which can conduct OSPF route summarization. (To market a summary route from one OSPF region to another, use the area assortment command to the ABR.)
Eventually, an ASBR is definitely an OSPF router which is doing route redistribution by injecting routes from An additional resource to the OSPF domain. This is actually the other OSPF router variety that can perform route summarization; to summarize routes being redistributed into OSPF, make use of the summary-tackle command to the ASBR.
There are many commands you can use to find out the router varieties within a offered OSPF region. The command “show ip ospf” will Display screen quite a bit of information concerning the community router, which consists of regardless of whether that router is acting as an ABR or ASBR. To see the routes on the ABRs and ASBRs with the regional router, run “demonstrate ip ospf border-routers”.
