Once you’re getting ready to pass the BSCI exam on the way in which on the coveted Cisco CCNP certification, you can be promptly confused via the sheer number of BGP and OSPF awareness it's essential to exhibit a mastery of. Just one set of details that some BSCI and CCNP candidates undervalue would be the dissimilarities between the OSPF router sorts. http://www.thefreedictionary.com/토토사이트
An OSPF Internal router has a person rule – it needs to have all its interfaces in only one region. It doesn't suggest that area has to be Spot 0.
An OSPF Spine router can be a router with at the least a single space while in the OSPF spine region, Region 0. A router may be each an Inner and Backbone router if all its interfaces are in Region 0.
A place more info Border Router has a minimum of a person interface in Region 0 and A further interface in a very non-spine spot. ABRs are amongst two router types that can perform OSPF route summarization. (To promote a summary route from a single OSPF location to another, use the world vary command on the ABR.)
At last, an ASBR is surely an OSPF router that may be doing route redistribution by injecting routes from Yet another supply into the OSPF area. This can be the other OSPF router style that may conduct route summarization; to summarize routes staying redistributed into OSPF, make use of the summary-tackle command over the ASBR.
There are various commands You should use to determine the router types inside a presented OSPF spot. The command “show ip ospf” will Display screen quite a bit of information concerning the community router, which involves no matter whether that router is acting as an ABR or ASBR. To begin to see the routes towards the ABRs and ASBRs in the community router, run “demonstrate ip ospf border-routers”.
