Blueprint mapping and rack strategy
Week 1

10-12 hours this week

  • Download the CCIE Enterprise Infrastructure v1.1 blueprint PDF from learningcontent.cisco.com and convert every numbered subtopic into a checklist row
  • Download the CCIE Enterprise Infrastructure equipment and software list from Cisco and match your practice environment to the listed software versions
  • Decide your practice platform: Cisco Modeling Labs Personal at 199 USD per year, Personal Plus at 349 USD, or a vendor rack rental
  • Confirm you already hold a valid 350-401 ENCOR pass, and check its three-year expiry date in the Certification Tracking System
  • Create your profile in the Cisco Expert Level Certifications Tracker so you can see lab availability and download a visa invitation letter if you need one
Switched campus to lab depth
Week 2

14-16 hours this week

  • Build a four-switch topology and tune PVST+, Rapid PVST+ and MST until you can force any root bridge on demand
  • Configure EtherChannel misconfiguration guard and deliberately trigger it, then recover
  • Practise manual VLAN pruning, extended range VLANs, voice VLAN and native VLAN changes under time pressure
  • Configure UDLD, CDP and LLDP and verify neighbour discovery from both ends
  • Work errdisable recovery, MAC address table management and Layer 2 MTU changes into a single timed drill
IGP depth and VRF-aware routing
Week 3

14-16 hours this week

  • Build EIGRP named mode with wide metrics and prove the difference against classic metrics on the same links
  • Configure query propagation boundaries with stub and leak maps, then force a stuck-in-active condition and resolve it
  • Tune OSPF with LSA throttling, SPF timers, stub router advertisement and prefix suppression
  • Configure VRF-Lite and VRF-aware routing with BGP, EIGRP, OSPF and static in one topology
  • Leak routes between VRFs using route maps, then repeat the exercise using VASI
BGP and redistribution
Week 4

14-16 hours this week

  • Build iBGP with route reflectors and eBGP with peer groups, dynamic neighbours and 4-byte AS numbers
  • Practise attribute manipulation, conditional advertisement, outbound route filtering and standard and extended communities
  • Write AS path regular expressions and test them against a multi-AS topology
  • Redistribute between BGP, EIGRP, OSPF and static in a topology with two redistribution points, then fix the resulting loop
  • Add Bidirectional Forwarding Detection and measure convergence before and after
Multicast
Week 5

12-14 hours this week

  • Configure PIM sparse mode with static RP, then convert to BSR, then to Auto-RP on the same topology
  • Build IPv4 anycast RP using MSDP and verify source active messages
  • Configure PIMv6 anycast RP and compare the mechanism to the MSDP approach
  • Configure Source Specific Multicast with IGMPv3 and prove the channel join
  • Apply multicast boundaries, RP announcement filters, IGMP filters and IGMP querier settings
Transport technologies
Week 6

12-14 hours this week

  • Build an MPLS core with LDP and verify label bindings, then use MPLS ping and MPLS traceroute to prove the LSP
  • Configure MPLS L3VPN with MP-BGP VPNv4 and VPNv6 and PE to CE routing using BGP
  • Build DMVPN Phase 3 with dual hubs, then break NHRP and IPsec deliberately and practise isolating each failure
  • Configure static point-to-point GRE tunnels and route across them
  • Time yourself: the blueprint gives this domain 15 percent, so cap your effort accordingly
SD-Access
Week 7

14-16 hours this week

  • Build a fabric on Catalyst Center: manual underlay first, then LAN automation with Plug and Play
  • Onboard hosts with authentication templates and port configuration, and add extended nodes
  • Configure macro segmentation with virtual networks and micro segmentation with SGTs and SGACLs
  • Practise border handoff for SDA transit, SD-WAN transit and IP transit, plus fusion router peering
  • Configure Layer 2 border handoff, L2 flooding and native multicast in the fabric
SD-WAN
Week 8

14-16 hours this week

  • Bring up vManage, vBond and vSmart and onboard WAN Edge routers with system IP, site ID, org name and vBond address
  • Build CLI templates, feature templates and device templates and understand which overrides which
  • Configure OMP attributes, route aggregation and redistribution, plus BGP AS path propagation
  • Write centralized data policies, application-aware routing policies and control policies, then verify the traffic path changes
  • Configure TLOC extension and localized access lists and route policies
Security, services and QoS
Week 9

14-16 hours this week

  • Configure Control Plane Policing and protection, then AAA with a fallback to local authentication
  • Build the full IPv6 first-hop security set: RA Guard, DHCP Guard, binding table, device tracking, ND inspection, Source Guard
  • Configure all five NAT variants in the blueprint, ending with VASI NAT
  • Build end-to-end Layer 3 QoS with MQC including NBAR classification, DSCP marking, policing, shaping and HQoS
  • Configure DHCPv6 prefix delegation alongside SLAAC and verify address assignment on the client
Automation and programmability
Week 10

14-16 hours this week

  • Write EEM applets that react to syslog patterns, interface events and timers, and verify each fires
  • Use guest shell with the CLI Python module and the EEM Python module to collect and act on device state
  • Drive the vManage API from Python requests and from Postman against both monitoring and configuration endpoints
  • Issue GET, PUT and POST requests to the Catalyst Center API on the free Cisco DevNet Sandbox
  • Configure a gRPC on-change telemetry subscription and confirm the collector receives updates
Design module preparation
Week 11

12-14 hours this week

  • Practise design scenarios in which you never touch a command line: choose topologies, justify protocol selection, size failure domains
  • Rehearse the no-going-back constraint by answering timed question sets without revisiting earlier answers
  • Work through the CCIE Enterprise Learning Matrix from Cisco to find design-oriented content you have skipped
  • Take a graded practice lab from a vendor such as INE and score the Design module separately from the configuration module
  • Write a one-page decision framework for SD-Access versus SD-WAN versus traditional campus and memorise it
Full eight-hour rehearsals and booking
Week 12

16-20 hours this week

  • Run at least two full eight-hour mock labs on consecutive weekends, three hours design then five hours configuration, with no phone
  • Practise saving configurations frequently, since Cisco states proctors are under no obligation to save your work
  • Rehearse a ten-minute troubleshooting cap on any suspected equipment fault before you would escalate to a proctor
  • Book the lab through the Cisco Expert Level Certifications Tracker, paying by credit card or Cisco Learning Credits, and note that rescheduling within three calendar days is not permitted
  • If you need a visa, download the visa invitation letter from the tracker and apply at least 10 to 12 weeks before the exam date
Working Full-Time Schedule

Hours/week: 7 hours

Saturday: 4-5 hours of focused study

Sunday: 3-4 hours of practice tests

Longer timeline but sustainable. Review flashcards on weeknights for 15-20 minutes to maintain retention.
