Posted on by admin

Due to a more complex network topology (because of the desire to save money) I recently had to implement iBGP routing inside a VRF on a cluster of Cisco Nexus switches.

Configuring iBGP (Internal Border Gateway Protocol) within a VRF (Virtual Routing and Forwarding) instance on a Cisco Nexus switch involves several steps. Below is a step-by-step guide to help you set it up: Continue reading “iBGP inside VRF configuration on a Cisco Nexus switch”

Posted on by Neofit Solovan

The code upgrade procedure for the Cisco 2504 Wireless Lan Controller is not that different than the one for the Cisco 5520 described in details here. This time I will keep it short, simple and to the point.

Worth mentioning that the Cisco 2504 it is now EOL and will be supported by Cisco a few more years.

You should check the release notes and confirm your wireless access points are supported by this version of code.
You may also look at the compatibility matrix for Cisco Prime if you are using that. Some of the features might stop working and you’ll have no idea why.

Posted on by Neofit Solovan

Right, this is a fairly easy procedure. However, when I first touched an IOS-XE bin image I managed to nicely transform a stack of 3 x Catalyst 3850 into a lovely expensive brick. This happened back in 2014 only because I thought I have to change the boot statement to “tell” the stack what file to use to boot. I was very wrong and that caused me a lot of pain and misery. I also hit a bug with that particular version of code. About bugs, in a different post.
Just double check the running version of code, make sure you’re on 3.x.x and follow the below steps:
