Cisco CCNP 먹튀검증 Certification / BSCI Test Tutorial: Comparing IRDP And HSRP
To move the BSCI exam, you have to know the difference between IRDP and HSRP. Though they've a similar primary functionality, the Procedure and configuration of each are absolutely various.
The intention of the two is to allow hosts to swiftly find out a standby router when the first router fails. IRDP is commonly used by Windows DHCP shoppers and several Unix versions, however, you do see it in Cisco routers too. IRDP is described in RFC 1256.
IRDP routers will multicast Hi there messages that host units hear. If a bunch hears from multiple IRDP router, it will eventually choose one as its Principal and may start using the other router if the principal it’s chosen goes down.
HSRP is actually a Cisco-proprietary protocol that is created for speedy cutover to the secondary router if the first fails, although the host gadgets don’t “see” either the first or secondary router. The hosts use a Digital router as their default gateway. This Digital router has its have IP and MAC deal with! All the although, the router decided on as the main is definitely the 1 carrying out the routing. If the main router goes down, the secondary router swiftly requires about without any key interruption to community services.
The HSRP routers communicate by multicasting updates to 224.0.0.2, and its by means of these hellos which the HSRP routers pick which router is primary and that is secondary. HSRP is outlined in RFC https://www.washingtonpost.com/newssearch/?query=먹튀검증 2281.
The configuration of every of those might be lined inside a foreseeable future tutorial. Meanwhile, I urge you to definitely read the RFCs outlined on this page, and pay a visit to www.cisco.com/univercd to examine the configurations and possibilities obtainable for both equally of such critical protocols.
