ISIS between ( IOS-XE and IOS-XR) peer not establish Hi all, I have two router ( IOS-XE ( cisco 3850) and IOS-XR ( ASR9K ), These two router connected and i have VLAN1000 peering between them using OSPF. Now i need to use the same VLAN to enable ISIS with tag mpls between them. I configured the two side as you can see below but i cant have neighbor between them, IOS-XE. router isis mpls.
Cisco hardening guides for IOS, IOS-XR and NX-OS devices. Patching routing and switching infrastructure in any organisation is often delayed, sometimes due to the potential impact on production.
IOS-XR. IOS XR is what the Mirror Universe version of IOS would look like. Much like IOS XE, IOS XR does away with the monolithic kernel and shared memory space of IOS Classic. XR uses an OS from QNX to serve as the base for the IOS functions. XR also segments the ancillary process in IOS into separate memory spaces to prevent system crashes.IP Routing on Cisco IOS, IOS XE, and IOS XR presents each protocol conceptually, with intuitive illustrations, realistic configurations, and appropriate output. To help IOS users master IOS XE and IOS XR, differences in operating systems are explicitly identified, and side-by-side feature command references are presented.With the recent announcement that IOS-XR will now be available on a curated set of third party network hardware, let’s dive a little deeper into technical details of the integration. In this ongoing series of technical blogs, we’ve demonstrated how IOS-XR with model driven APIs at every layer of the stack enables us to easily integrate with a wide variety of community tools and protocols.

Supported platforms: ASA, IOS, IOS-XE, IOS-XR. This tool utilizes Cisco TAC knowledge in order to analyze a Cisco supported device and detect known problems such as system problems, configuration mistakes, and best.Read More
A vulnerability in the Topology Discovery Service of Cisco One Platform Kit (onePK) in Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient length restrictions when the.Read More
Cisco said that one vulnerability affects Cisco IOS, IOS XE, IOS XR, and NX-OS Software. Five vulnerabilities affect both Cisco IOS and IOS XE Software. Six vulnerabilities affect Cisco IOS.Read More
The classical IOS, the IOS XE and the IOS XR. Cisco IOS: Classical IOS is on the market for a long time. I start to work with IOS version 10 on Cisco 2500 routers. You will find this IOS on entry level routers like ISR or Enterprise switches like 6500 or 3750. This IOS is a monolythic OS. That means that all the features are in one file and if one function on the system fail most likely all.Read More
I want to factory reset IOS-XR. The router used is ASR9000. I'm used to do that easily in IOS doing config-register 0x2102, write erase followed by a reload. I search on documentation, but found no explicit information. What is the correct method for doing a factory reset on the ASR9k running IOS-XR?Read More

Multicasting in IOS, IOS XE, IOS XR for IPv4 and IPv6 Disclaimer. I don’t pretend to cover everything about the protocols or mechanisms that we have in multicasting. I just explain what we use nowadays, why we use it, how it works and how to configure it. Introduction I’ve started to write this article with the idea to show which bugs I’ve found while studying multicast topics at IOS XR.Read More
