Back after a long time, sharing how we can test remote access vpn connectivity using Cisco VPN Client . First of all, we need to have any Virtual Machine – VMWARE Virtual Machine or Oracle Virtual Box with any OS installed in it . We will try out with simple topology : 1. Configure
Scapy is a well known packet manipulation framework developed in Python. It could be quite useful for people want to understand network at people level. Though it is used mostly by security engineers or penetration testers but i also suggest for Network Engineers apart from using Wireshark. Below are the few resources from where you can learn
Today i got mail from CISCO as reminder for Cisco Webinar on Cyber Security . The whole Series is about to protect from network from hacker by thinking like them . The whole Series consist of 10 meets. I will going to update about all . Join the today’s meet 1 Feb will
INE- One of the leader in Cisco Online training providing Video Bootcamp for the whole CCNAcourse for free till 31st December 2011. The Course instructor is Brian McGahan, CCIE #8593, One of best Cisco Course Trainer so there should be no doubt about the quality of material if you are getting at free of cost. It would be really great
This is just an experiment i was trying to do, may be doesn’t make any sense in real life networks. Experiment: Define static routes on R1- R2- R3 such end to end interfaces from R1-R2 and R2-R3 all interfaces have different subnet . Configuring IP addresses on interfaces
Cisco Systems on 23,april made an annoucement about the introduction of Cisco Certified Technician (CCT) to its career Certification Program. So, with this new Cisco Certified Technician (CCT) training and certification program, Cisco Systems is targeting even the Network Technicians who perform onsite support and maintenance for Cisco infrastructure for R&S , TelePresence and Data
We will be using a simple topology to understand the concept : We made loopbacks each on R1& R2 and configure default static-routing with next hop interfaces on R2.
We will going to look in this post on how can we make it possible to communicate RIPv1 and Rip v2 . Topology is given below : R1 – RIP V1 protocol R2 – RIP V2 protocol R3 – S0/0 in RIP v1 and S0/1 in RIP v2.
According to cisco documentation, all the below conditions need to be met in order for the OSPF to set a non-zero Forwarding address 1. OSPF is enabled on the ASBR’s next hop interface 2. ASBR’s next hop interface is non-passive under OSPF 3. ASBR’s next hop interface is not point-to-point 4. ASBR’s next hop interface
Below are some key points to remember on Redistribution. When redistributing from OSPF in to BGP, by default, BGP only accepts internal routes not external type-1 or type-2. Also, the routes learnt via iBGP will not be redistributed into OSPF with the use of “redistribute” command until “bgp redistribute-internal” is used under bgp process. When
