12.4T would cover everything but licensing. To cover everything, you would need at least IOS 15.0, but I think the only topic you wouldn't be able to cover is licensing. These are the only packages that support IPv6 on routers. If there is an router on the network with ipv6 enabled and sending out router annoucements, an ipv6 address can be assigned by using the autoconfigure option. For routers, you will want Advanced IP Services or Advanced Enterprise on all of them.
Configure the IPv6 global unicast address on an interface. R1(config-if)# ipv6 address 2001:db8:0:1/64Īn ipv6 address can be assigned to an interface by just giving it an ipv6 network prefix and selecting the eui-64 option Enable IPv6 routing on a Cisco router using the ipv6 unicast-routing global configuration command.
Show ipv6 routes //displays all ipv6 routes on the device Example Configurationss Alternatively, you can force a DHCPv6 PD at any time with the following command: 'clear ipv6 dhcp client Dialer0'. The configuration listed above contains a workaround for this problem. "brief" can be appended to only display status and ipv6 addresses Cisco IOS currently fails to immediately renew the DHCPv6 PD lease after PPP renegotiates. Show ipv6 interface //displays ipv6 configuration details of interfaces
#CISCO IOS VERSION IPV6 SUPPORT MAC#
Ipv6 address eui-64 // assign ipv6 address built from the prefix and interface's MAC address Ipv6 address autoconfig // autoassign ipv6 address if ipv6 if router annoucements are present Ipv6 address / // assigns ipv6 address to interface Ipv6 route // configures a static route on device For one option, you configure the entire 128-bit IPv6 address, and for the. Ipv6 unicast-routing //a global configuration that enables unicast routing There are two options for static configuration of IPv6 addresses on Cisco routers. The following commands are used to enable IPv6 networking and verious IPv6 suboptions. There are around 200 useful operations in CyberChef for anyone working on anything vaguely Internet-related, whether you just want to convert a timestamp to a different format, decompress gzipped data, create a SHA3 hash, or parse an X.509 certificate to find out who issued it.On Cisco IOS, IPv6 settings are often disabled by default. The vulnerability is triggered when an affected device processes a malformed IPv6 packet.
#CISCO IOS VERSION IPV6 SUPPORT SOFTWARE#
It is hoped that by releasing CyberChef through GitHub, contributions can be added which can be rolled out into future versions of the tool. Cisco IOS Software contains a vulnerability in the IP version 6 (IPv6) protocol stack implementation that could allow an unauthenticated, remote attacker to cause a reload of an affected device that has IPv6 operation enabled.
It should also appeal to the academic world and any individuals or companies involved in the analysis of digital data, be that software developers, analysts, mathematicians or casual puzzle solvers. It is expected that CyberChef will be useful for cybersecurity and antivirus companies. Simple functions can be combined to build up a "recipe", potentially resulting in complex analysis, which can be shared with other users and used with their input.įor those comfortable writing code, CyberChef is a quick and efficient way to prototype solutions to a problem which can then be scripted once proven to work. Complex techniques are now as trivial as drag-and-drop. HSRP IPv6 uses a different virtual MAC address block than does HSRP for IP: Port number 2029 has been assigned to HSRP IPv6. The interface is designed with simplicity at its heart. HSRP version 2 must be enabled on an interface before HSRP for IPv6 can be configured. configure an IPv6 global unicast address on an interface. After going to the configuration mode with configure terminal command, to enable IPv6 on a Cisco router, ipv6 unicast-routing command is used. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression.ĭigital data comes in all shapes, sizes and formats in the modern world – CyberChef helps to make sense of this data all on one easy-to-use platform. enable IPv6 routing on a Cisco router using the ipv6 unicast-routing global configuration command. A simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages.
