Hi Friends, Below is testing report of Load balancing and back up scenario using Maipu 1800 Routers.  Objective-  Maipu 1800 CPE router need to perform load balancing in between two outgoing interfaces F0 and F1  If one WAN link is down, then another wan link will be primary, vice versa. As the faulty link is restored, Both WAN link should do load balancing for LAN traffic.

Hi All friends, Many time we came across requirement of IPSec configurations. Maipu every Router support IPSec. In this section, I will share IPSec Configuration template. It will help you to understand Maipu IPSec configuration steps. Maipu IPSec configuration is having different command line than other vendors. Before looking in details of IPSec template, let’s take a overview of

Hi All, I was doing a inter-operability testing for Maipu ME switches and Cisco 2960 and ME switches for LACP features (on mode and LACP mode).  It is working absolutely fine, In case any body is having any issues in configuration, They can refer this testing process and do it.  I want to share testing report with you. It will help you in any future deployments.  This post is for LACP mode.

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

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
