Cisco CCNP Certification / BSCI Test Tutorial: Comparing IRDP And HSRP
To pass the BSCI Examination, you need to know the difference between IRDP and HSRP. Whilst they may have a similar primary functionality, the operation and configuration of each and every are thoroughly distinct.
The aim of 토토사이트 the two is to permit hosts to immediately find out a standby router when the key router fails. IRDP is usually used by Home windows DHCP purchasers and several other Unix variants, however , you do see it in Cisco routers also. IRDP is described in RFC 1256.
IRDP routers will multicast Hi messages that host gadgets hear. If a number hears from more than one IRDP router, it is going to select one as its primary and may start out utilizing the other router if the principal it’s selected goes down.
HSRP is usually a Cisco-proprietary protocol that may be created for fast cutover to your secondary router if the principal fails, although the host gadgets don’t “see” both the key or secondary router. The hosts make use of a Digital router as their default gateway. This Digital router has its personal IP and MAC deal with! The many although, the router selected as the main is in fact the one performing the routing. If the principal router goes down, the secondary router immediately normally takes in excess of without having main interruption to network services.
The HSRP routers communicate by multicasting updates to 224.0.0.two, and its through these hellos which the HSRP routers decide which router is Most important and that is secondary. HSRP is outlined in RFC 2281.
The configuration of http://www.bbc.co.uk/search?q=먹튀검증 each of those will likely be lined inside of a foreseeable future tutorial. In the meantime, I urge you to definitely read through the RFCs talked about in this post, and pay a visit to www.cisco.com/univercd to examine the configurations and alternatives readily available for both equally of these very important protocols.
