Using VMware and CDP information (HP and Cisco Switches)

October 8, 2014Cisco, HP, Networking, VMwarecdp, Cisco, esxcfg-vswitch, HP, information, lldp, Networking, vmnic, VMwareDean

So on of the most valuable networking features of VMware is setting up CDP information or LLDP (if using non cisco devices). We can see exactly which VMNIC is plugged into which port.

ESXi can receive and display CDP information within the client or web client, but this doesn’t work with HP switches which use LLDP, which you will see in the below examples for both vendors.

Below the environment is plugged into a HP switch and no CDP information is being displayed into the standard switch, however we can send CDP information from VMware ESXi to the HP switch. (But from a Cisco Switch the information does show)

Creating VPN tunnel between Cisco ASA and Watchguard XTM

Today was the second time I’ve done this in around a year, it’s a little uncommon to be honest, which means googling advice on how to do it, is a bit thin.

Todays walk through is also made even more different by the fact that at the branch site containing the Watchguard, its connected to a Cisco 857w router, with a Public IP address NAT’d to it due to the site having an ASDL connection.

See the below diagram I’ve sketched up in visio;

It’s actually easy enough to setup, the official documentation on the Watchguard is here, but doesnt cover it all.

Cisco CCNP Training Course – Day 4 – ROUTE

Day 4 – Kind of, the course has mostly followed each of my post, however I have kind of mixed and match a few things so they flow better.

Also i’ve found out how to truncate my posts on the homepage, so it says, click here to read more, or something to that effect!

As you can imagine, something’s whilst labbing a few things, it can all get muddled.

Just one more quick note, I bought the revision materials from here https://www.ccnpguide.com

I’ve not had a change to look through them properly, but they are well set out and look like a fantastic quick revision guide with all the commands and tidbits of info you need for the exam.

So the topics that will be covered in this one are;

OSPF Summerization
OSPF Default Route
LSA/LSU Types
Special Areas (Stubby and Not-So-Stubby-Area)
OSPF Redistribution
Routing Protocol – Route Filtering
ACLs for route filtering
Route-Map for route filtering
Prefix-List for route filtering
Policy-Based Routing
IPv6
IPv6 with OSPFv3
IPv6 OSPFv3 Virtual-Link

On to-day 3, most of you have probably noticed that I am posting these online a day behind when I actually take the class, which is helpful, as I spend the evening typing up my notes and building the topologies etc in Visio. It’s a good way to re-cap stuff.

So I cheated a bit on the last post as I stopped before OSPF, so we hit all the main points in one big go.

So heres a quick summary of what will be covered in this post;

OSPF
OSPF Timers
Packet Types
Hello Packet
OSPF Convergence
OSPF Convergence Troubleshooting
Router ID
OSPF Virtual-Link
OSPF Authentication
DR/BDR Concept
Point-to-Point Links
Broadcast Multi-Access Network
Non-Broadcast Multi-Access Network
Point-to-Multipoint
Point-to-Point Subinterface
