How To Authenticate MD5 for BGP Peers. BGP (Border Gateway Protocol) Peers MD5 Authentication is a security feature used in BGP, the protocol that manages how packets are routed across the internet through different networks (autonomous systems). This feature enhances security by establishing a secure connection between BGP peers (routers) using MD5 (Message Digest 5) hashing. Key Points… Read More »
The Border Gateway Protocol (BGP) is a complex, advanced distance routing protocol utilized primarily for exchanging routing information between major Internet Service Providers (ISPs) and larger client sites. It uses the Best Path Selection Algorithm to choose efficient routes, supporting the complexity of the public internet.
What Is CIDR? CIDR (Classless Inter-Domain Routing) was introduced in 1993 (RCF 1517) replacing the previous generation of IP address syntax – classful networks. CIDR allowed for more efficient use of IPv4 address space and prefix aggregation, known as route summarization or supernetting. CIDR introduction allowed for: CIDR allows routers to group routes to reduce the bulk of… Read More »
If you are connected to the Internet through a Wired or Wireless network (USB, broadband Modem, or dial-up), most times you deeply rely on your computer and software for protection from viruses and other threats. If you are connected through a router, it might be able to help; because most routers are equipped with a firewall. This helps… Read More »
This post explains how to configure BGP using loopback addresses, especially with iBGP. It discusses this configuration within the context of RouterHQ and BranchOffice from AS 556.
