Cisco IOS XR Workbook

Cisco IOS XR Practice Labs This workbook aims to give network engineers the chance to practice new Cisco software : IOS XR combined with Cisco IOS software , the workbook mainly focus on MPLS technologies and different MPLS VPN implementantions using GNS3 to simulate , it’s a good preparation guidefor both CCNP SP and CCIE SP tracks
