Hi , I want to share one testing report with all of you. This is majorly focused on Fail over configuration with static routing.. Below are objectives for testings... Objective -  R1 Client Router both interface should be UP every time. PC should ping 20.1.1.1 Loopback interface continuously.  Auto Failover should happen. One time one port should forward traffic to ISP router. As the

Hi, Today one of my client raised a query about MP 3840 MTU details about all 4 Gig interface.  As MP 3840 is aggregation router, some time we need to modify the MTU of interface as per requirement.  So I would like share same details here, Which can be helpful for all.  MP 3840 Gig 0, you can configure max MTU of 1800 under Gig 0  interface for any peer device. But Gig 1/2/3 , if speed is

Hi , In this section. I will share the information of SNMP traps supported by Maipu Routers. Many times we require traps information for notification and monitoring.  Maipu Routers support below SNMP traps: snmp-server start snmp-server view default 1.0.8802 include snmp-server view default 1.1.2 include snmp-server view default 1.3.111 include snmp-server view default 1.3.6.1 include

In last post, we have seen all basics of IPv6 headers. As we know the IPv6 header is very efficient as compared to IPv4 header due to less fields in IPv6 header and extension header approach in Next header field. These extension headers are added only if needed. Extension headers are appended after the basic datagram header as per requirements. The extension headers numbers may be more in a

As we discussed in last post about IPv6 and IPv4 headers.  In this post we will see in details about it.IPv6 header  design is focused mainly on simplicity - to keep the datagram as simple as possible and to keep the size of the headers fixed. The  reason for this was to increase processing performance - simple constant size headers can be processed quickly, at or very close to wire-speed. The

Hi , As we all know IPv6 is on its way to enter in our life. Why I am saying life ..?Since in one year it is planned to implement in India and hopefully I know its same situation everywhere. India's Internet Gateway and all Service provider is all equipped and ready with IPv6 Internet services.  As right now we are using so many devices, Which are taking us on Internet like Mobile, Laptop, PC

This section will explain you about 802.1p priority field in L2 header.This field is majorly used in L2 QOS.        The 802.1p priority is located in the L2 packet header. It is used when you don’t want to analyze the L3 packet header, but need to ensure QOS in L2 environment. As shown in below diagram, the 4-byte 802.1Q header contains 2-byte TPID (Tag Protocol Identifier valued as 0x8100) and

Today we will discuss about Link aggregation, This is very important topic in switching. This is many times used in Enterprises network for trunking. Basically this will help to bind several physical links together to form a logical link and it can be used to increase link bandwidth for trunk. Meanwhile, each aggregation member link can achieve dynamic backup with each other to provide higher

In this scenario, We are using Maipu 3400 switches and enabled QinQ technology in all switches to achieve ELAN and make reachable all connected routers. There is one more way of configuration using evc commands. But I feel this is easy to configure. So I
