10BASE5 is a technical name for thick Ethernet or thicknet and was the first commercially available variant of Ethernet. The technology was standardized in 1982 as IEEE 802.3. 10BASE5 uses a thick and stiff coaxial cable up to 500 meters (1,600 ft) in length. Up to 100 stations can be connected to the cable using […]

There are various methods of Filtering Type 5 LSA in OSPF that we are going to discuss below in this article. On ASBR, block the prefix using distribute-list. On ASBR, block the prefix while redistribution into OSPF. On ASBR, block the prefix while summarization.On any ABR block the Forward Address the if Type 5 LSA […]

This is an important blog on Learning IPv6 – Important Points, its Importance and advantages of IPv6. IPv6 is the replacement Internet protocol for IPv4. It corrects some of the deficiencies of IPv4 and simplifies the way that addresses are configured and how they are handled by Internet hosts.IPv4 has proven to be robust, easily […]

In this article we are going to discuss EIGRP Packet Format in detail. Enhanced Interior Gateway Routing Protocol (EIGRP) incorporates five packet types that are Hello, Update, Query, Reply, ACK for its operation. Each of these five EIGRP Packets has a common header fields and therefore it is important to know the EIGRP Packet format […]

EIGRP Graceful Shutdown feature is designed to improve EIGRP network convergence and it uses Goodbye message to communicate this information to the neighbors. Using Graceful Shutdown in EIGRP feature, a Goodbye Message is broadcasted when an EIGRP routing process is shut down, to inform adjacent peers about the impending topology change. This feature allows supporting […]

This Blog explains BGP 4-Byte AS in detail. During initial BGP development, it was assumed that availability of a 16 bit would be enough for AS assignment. AS is also be defined as a 16bit number with 65536 unique Autonomous System numbers. The IANA Authority manages the available BGP Autonomous System Numbers (ASN) pool, with […]

10BASE2 is technical name for Ethernet, thinnet coaxial cable and  is a variant of Ethernet that uses thin coaxial cable terminated with BNC connectors to build a local area network.During the mid to late 1980s this was the dominant 10 Mbit/s Ethernet standard, but due to the immense demand for high speed networking, the low […]

This blog explains various ways of FILTERING TYPE 1 LSA1 in OSPF along with config examples. Generally you cannot filter LSA1 from flowing b/w the routers in an area. But you can block the ping/traffic for Intra Area prefixes.  But we have a trick command to completely filter Type 1 LSAs in an Area. Please […]

When the concept of Networking actually came into existence, computer devices of same  manufacturer could only communicate with each other.  There was no standard using which devices of multiple vendors/manufacturers could communicate. For example,companies ran either a complete DECnet solution or an IBM solution, not both together. There was a need to a standard mechanism […]

HomeDNSHow to configure Router as DNS Server Domain Name System (DNS) is used to resolve website names (or host-names) example www.testdomain.com into IP addresses 90.1.1.1. This article guides you how to configure a Router as DNS server. Let’s discuss a network issue to understand the importance of DNS.  You are a Network Engineer in an […]

While the multicast traffic is sent, a connectivity or a path is formed between a receiver and the multicast source which is analogous to a Tree like formation known as Multicast Distribution Trees in which Source is the root and receivers are the leaves of the Multicast Tree. There are two types of Multicast Trees. […]

HomeTRAFFIC ENGINEERINGPOLICY BASED TUNNEL SELECTION – PBTS Policy Based Tunnel Selection (PBTS) is analogous to Class Based Tunnel Selection (CBTS) with only difference that you cannot configure CBTS on IOS-XR devices to manipulate/route the traffic based on EXP/DSCP/Precedence values, therefore we use PBTS on IOS-XR devices. Please refer to CBTS link for more information on […]
