The CCNA 200-125 exam includes OSPF as one of several routing protocols (RIP, EIGRP, OSPF, BGP). The new CCNA 200-301 has OSPF, and OSPF only. This post details how to take advantage of some Packet Tracer files to re-create the
First, think of TCP headers, and the source port and destination port. Then think about the predictable port – the well-known port – and whether it will be the source or destination port. Then think about the syntax of the
#CCNA ACL questions can uncover your weaknesses even without a detailed and complicated list of requirements to place in a single ACL. In fact, my “Acing the CCNA Exam” live course on Safari features ACL Port Matching as one of
Of all #CCNA topics in the ICND2 half of CCNA, Spanning Tree Protocol (STP) looms with more intimidation than most. As for Mastering STP verification, the process begins with mastering the show spanning-tree command. This latest sample question focuses on
To analyze Spanning Tree for #CCNA, you need to think about the root switch, then the root ports on the non-root switches, and then designated ports. That analysis usually begins with the show spanning-tree command – a command that packs
Extended IPv4 ACLs? No problem. Matching packets going towards the client? A little more of a problem. Deciding whether you need to match ARP and OSPF in your ACL? Even more of a problem. This latest drill makes you think
This next Extended IPv4 ACL Drill continues to focus on some key ACL concepts. You have to think about where the ACL will reside, and for what direction of packet flow, before choosing the syntax of the commands. This next
The previous post listed a set of ACL requirements that require an IPv4 Extended ACL. Your job: using those requirements, configure an extended named ACL. Of course, this post makes no sense without the post that states the requirements, so check
Extended Access Control Lists (ACLs) can be a challenge for many reasons. In the first few posts in this series, these ACL exercises will focus on just a few of those issues. In particular: The concept and syntax to match
EIGRP Enabler exercise 3 asked you to configure four routers, specifically to add the EIGRP network commands. If you’ve not seen these before, check out the Routing Protocol Enabler intro post. Otherwise, it’s straightforward, so keep going!
