Cisco CCNP Enterprise Training | ENCOR + ENARSI

Learn how layer 2 and layer 3 forwarding work, including vlan concepts, mac addressing, arp, and routing between subnets, plus an overview of Cisco express forwarding and process switching.

Understand Cisco express forwarding (CEF), a software switching mechanism using the forwarding information base and adjacency table built from routing and ARP data to enable high-throughput packet forwarding.

Explore the spanning tree protocol and rapid spanning tree protocol to prevent layer two loops, covering root bridges, port roles, BPDU exchange, and transition states.

Master advanced STP settings, including root bridge placement and timer options. Implement root guard, BPDU guard, BPDU filter, STP loop guard, and UDLD to protect access and uplink links.

Configure advanced spanning tree features, including root bridge placement, root guard, portfast, bpdu guard, bpdu filter, and loop guard, with practical lab demonstrations.

Explore how multiple spanning tree replaces the single common spanning tree with per-VLAN instance blocking, VLAN mappings, and MST configuration to optimize traffic across switches.

Configure mst across switches, assign Vlan ten and twenty to instance one, Vlan 99 to instance two, and Vlan four to instance three; set root bridges, block ports, and verify.

Explore the vlan trunking protocol (VTP) and its four switch roles—Http server, client mode, transparent, and off mode—and how VLAN creation on the Http server propagates to client switches.

Configure vlan trunking protocol with vtp in a six-switch topology, setting a http server and client roles, domain cnp, version 3, and using transparent switches to manage and distribute vlans.

Explore dynamic trunk protocol (DTP) and trunk negotiation between switch ports, detailing trunk, dynamic auto, and dynamic desirable modes, and securing unused ports.

Explore ether channel that aggregates links between two switches into one logical interface to boost bandwidth and provide redundancy, using PAgP or lacp with auto, desirable, active, or passive modes.

Configure etherchannel on four switches using static and dynamic methods to provide redundancy and load balancing, with trunking, port-channel interfaces, and load-balance options based on IP and MAC addresses.

Explore the fundamentals of IP routing, from static routes to dynamic protocols, and learn how interior and exterior gateway protocols like OSPF and BGP shape routing decisions.

Understand static routing concepts, including directly connected, recursive, fully specified, and floating static routes, and how administrative distance and next-hop decisions affect routing.

this lab demonstrates static floating routing between two routers, using recursive and full specified static routes with different administrative distances to create a valid and backup path.

Master static null routes and null interfaces to block traffic without access lists or CPU load, and prevent routing loops with summarized networks.

Configure static routes and implement a static null route to prevent the ISP and router loop. Validate with trace routes and show commands in a CCNP enterprise lab.

Configure ipv6 static routes in a lab by enabling ipv6 unicast routing and adding static routes on two routers to reach remote subnets; verify with ping and tracert.

Explore virtual routing and forwarding (VRF) to create separate virtual routers on a single physical router, isolating interfaces and routing tables between VRFs and allowing overlapping IP ranges.

Configure a management VRF and assign gigabit zero two and zero three as its members, enabling traffic separation on a router; verify with show ip route and show vrf brief.

Explore EIGRP fundamentals, including the dual algorithm for fast convergence and topology tables, with metrics like reported distance, feasible distance, and feasible successors, plus route summarization.

Configure a four-router EIGRP lab with IP addressing, speed settings, and subnets; establish neighbors, use passive interfaces, verify topology, routes, and metrics such as feasible distance.

Explore how OSPF uses link state advertisements (LSA) and the SPF algorithm to build a loop-free topology and a synchronized link state database. Understand DR/BDR elections and hello packets.

Walk through a four-router OSPF lab, configuring loopbacks, IP addresses, and the OSPF process with router IDs, network commands, passive interfaces, and neighbor adjacencies.

Learn how to place OSPF DR and BDR using priority, verify with show ip ospf neighbor, and adjust priorities to select DR and BDR in a lab.

Explore ospf network types, including point-to-point, broadcast, and loopback, and learn how to configure loopback interfaces to influence route learning and neighbor status in a lab environment.

Discover how OSPF areas group interfaces, backbone area zero, and area border routers to exchange routes via LSA types, with intra- and inter-area routing, path selection, and summarization.

Configure OSPF across six routers to form multi-area topology with area 1234, area zero, and area 56; designate router four as abr and apply subnets 1020 410, 1040 510, 1050 610.

Perform inter-area summarization on the OSPF ABR router two to summarize 172.16.0.0/16 subnet from area 12 into area 0, verify with show ip route OSPF; automatic null route prevents loops.

Practice configuring ospf route filtering with summarization, area boundary filtering, and local ospf filtering using not advertise, prefix lists, and distribute lists to control which subnets are advertised.

Learn OSPF v3 fundamentals, including support for IPv4 and IPv6 addresses, new LSA types for IPv6 prefixes, link-based shortest-path calculations, and manual neighbor setup using IPv6 link-local addresses.

Perform an ospf v3 lab across four routers, with area zero and area 34; router three is area border router; verify ipv6 neighbors and routes, and test connectivity with ping.

Enable OSPF v3 route summarization to shrink the link-state database. Configure area zero range under address family six unicast on the ABR to summarize 2001:db8 subnets.

The lab demonstrates configuring OSPF version three to carry IPv4 and IPv6, assign interfaces to areas zero and 34, and verify learned routes with show commands.

Explore BGP fundamentals, including autonomous systems, internal and external sessions, path attributes, and multiprotocol address families for IPv4 and IPv6, plus the open, keepalive, update, and notification messages.

Configure BGP in a four-router lab, implementing external and internal BGP, IPv4 address family behavior, neighbor activation, and prefix publication across AS 65,100; 65,200; and 65,300.

Practice BGP route summarization across three routers by aggregating 172.16.0.0/16 subnets into a single 172.16.0.0/22 prefix and validating a single route with the summary only command.

Configure multiprotocol BGP for IPv4 and IPv6 in a hands-on lab, verifying routes, publishing networks, activating neighbors, and validating with show commands.
