1 TSHOOT v2.0 Trubleshting and Maintaining Cisc IP Netwrks Curse Length: 5 Curse Delivery: Traditinal Classrm Online Live Curse Overview TSHOOT v2.0, a five-day ILT curse, includes majr updates and fllws an updated blueprint. (Hwever, nte that this curse des nt cver all items listed n the blueprint.) Sme lder tpics have been remved r simplified, while several new IPv6 ruting tpics have been added. The curse cntent has been adapted t Cisc IOS Sftware Release 15 and technically updated. The gal f the curse is t build upn the knwledge and skills frm CCNA Ruting and Switching and help yu expand cmpetencies t plan, implement, and mnitr a scalable ruting netwrk. Audience Learners wh aim t be netwrk prfessinals and wh have knwledge that is btained frm Cisc CCNA curses Prerequisites Layer 2 switching VLANs, VLAN access cntrl lists, prt security Switch security issues Link aggregatin prtcls STP Inter-VLAN ruting slutins FHRPs, including HSRP, VRRP, and GLBP Branch ffice peratins EIGRP OSPF Layer 3 path cntrl Redistributin BGP IPv6 Netwrking Tel E.
