Redistribution is necessary when routing protocols connect and must pass routes between the two.
Route Redistribution involves placing the routes learned from one routing domain, such as RIP, into
another routing domain, such as EIGRP.
While running a single routing protocol throughout your entire IP internetwork is desirable, multiprotocol routing is common for a number of reasons, such as company mergers, multiple departments
managed by multiple network administrators, and multi-vendor environments. Running different
routing protocols is often part of a network design.
LISP + GETVPN as alternative to DMVPN+OSPF+GETVPNJobSnijders
These slide are from a presentation I gave at the Cisco NAG2010 conference about using LISP to build large VPN's over the internet instead of regular GRE or DMVPN based setups.
SVR401: DirectAccess Technical Drilldown, Part 1 of 2: IPv6 and transition te...Louis Göhl
Take a sprinkling of Windows 7, add Windows Server 2008 R2, IPv6 and IPsec and you have a solution that will allow direct access to your corporate network without the need for VPNs. Come to these demo-rich sessions and learn how to integrate DirectAccess into your environment. In Part 1 learn about IPv6 addressing, host configuration and transitioning technologies including 6to4, ISATAP, Teredo and IPHTTPS. Through a series of demos learn how to build an IPv6 Network and interoperate with IPv4 networks and hosts. In Part 2 we add the details of IPSec, and components that are only available with Windows 7 and Windows Server 2008 R2 to build the DirectAccess infrastructure. Learn how to control access to corporate resources and manage Internet connected PCs through group policy. Part 1 is highly recommended as a prerequisite for Part 2.

Implementing an IPv6 Enabled Environment for a Public Cloud TenantShixiong Shang
"Implementing an IPv6 Enabled Environment for a Public Cloud Tenant" case study I delivered in OpenStack Vancouver Summit (May, 2015) jointly with Anik and Sharmin from Cisco System.
You may have hoped to retire before IPv6 became a reality, but unfortunately the IPv4 address exhaustion came too fast. For the rest of us, we’re going to bite off a small piece of the 15-year old IPv6 pie and talk about how to get started!
• Address format refresher
• IPv4 and IPv6 protocol comparison
• IPv6 neighbor discovery and auto-configuration
• Current migration and coexistence strategies
• ICMPv6, DHCPv6, and DNSv6
• How to get started at home
IDNIC OPM 2023: IPv6 deployment planning and security considerationsAPNIC
APNIC Network Analyst / Technical Trainer Awal Haolader gives the technical keynote presentation on IPv6 deployment and security considerations at the IDNIC OPM 2023, held from 5 to 7 December 2023 in Bandung, Indonesia.
Module 4: Configuring and Troubleshooting IPv6 TCP/IP
This module introduces you to IPv6, a technology that will help ensure that the Internet can support a growing user base and the increasingly large number of IP-enabled devices. The current Internet Protocol Version 4 (IPv4) has served as the underlying Internet protocol for almost thirty years. Its robustness, scalability, and limited feature set is now challenged by the growing need for new IP addresses, due in large part to the rapid growth of new network-aware devices.
Lessons
Overview of IPv6
IPv6 Addressing
Coexistence with IPv6
IPv6 Transition Technologies
Transitioning from IPv4 to IPv6
Lab : Configuring an ISATAP Router
Configuring a New IPv6 Network and Client
Configuring an ISATAP Router to Enable Communication Between an IPv4 Network and an IPv6 Network
Lab : Converting the Network to Native IPv6
Transitioning to a Native IPv6 Network
After completing this module, students will be able to:
Describe the features and benefits of IPv6.
Implement IPv6 addressing.
Implement an IPv6 coexistence strategy.
Describe and select a suitable IPv6 transition solution.
Transition from IPv4 to IPv6.
Troubleshoot an IPv6-based network.
3. Why Vertex-5
We had three choices for FPGA boards:
Virtex-5,Vertex-2 & Altera
Embedded tri-mode Ethernet MAC
wrapper is available only for Virtex-5 and
Vertex-6
Because of which we used Virtex-5 board
for our project.
4. Procedure
Implemented the Tri-mode
Ethernet MAC Wrapper
Implemented the IPv4 to
IPv6 conversion algorithm
Implemented the IPv6 to
IPv4 conversion algorithm
Combine two algorithms
to get the NAT64 module
8. Header Mapping
IPv4 IPv6
Ether Type: 0x0800 Ether Type:0x86dd
DSCP, ECN Traffic class
Header Length, Total Length Payload Length
Protocol Next Header
Time to Live Hop Limit
Ipv4 address Ipv6 address
13. Issues
Virtex-5 board only has one Ethernet port
though out NAT64 server needs at least
two ports.
Virtex-5 device designs of Tri-mode
Ethernet MAC require a Verilog LRM-IEEE
1364-2005 encryption-compliant simulator
ModelSim v6.6d
Cadence Incisive Enterprise Simulator (IES) 10.2
Synopsys VCS and VCS MX 2010.06)
Butany of those simulators are not freely
available
Editor's Notes
Monahriliyapaaannn
According to the slides, given by Dr. Pasqual, there are 3 types of FPGAtri-mode Ethernet MAC wrapper is free
We have to configure the TEMAC wrapper
The generated example design for this OpenSparc board will not work if implemented and downloaded to the board as is. We must make some configuration changes in the example design so that it works on the OpenSparc board. This is the most hardest part in our project
This is the timing diagramFor each ipv4 packet received, NAt64 send ipv6 packet after delaying 36 bytesData and FCS field is delayed by (76-x) bytes
This is the timing diagramFor each ipv6 packet received, NAt64 send ipv4 packet after delaying 36 bytesData and FCS field is delayed by 16 bytes
‘Ether type’ in ethernet header is used to determine whether this packet is ipv4 or ipv6How ipv4 packets and ipv6 packets are mapped each other
There are twomethosChipScope Pro Inserter flow (which is easy)(which we use)ChipScope Pro Core Generator flow
So, the single Ethernet port has to represent IPv4 network and IPv6 networkBecause of unavailability of functional and timing simulations, we have to rely on the hardware debug tools (ChipScope Pro Analyzer and wireshark). This make the project extremely difficult and time consuming (synthesizing, implementing and generating a programming file takes lots of time )
