BGP peers are established by manual configuration between routing devices to create a TCP session onport 179. A BGP-enabled device periodically sends keepalive messages to maintain the connection. What are the BGP attributes? There are four categories of BGP attributes: Well-known mandatory: Recogni...
What are BGP attributes? Overall, BGP tries to find the most efficient path for network traffic. But as noted above, hop count is not the only factor BGP routers use for finding those paths. BGP assigns attributes to each path, and these attributes help routers select a path when there ar...
BGP Finite State Machine The BGP Finite State Machine (FSM) has six states: Idle, Connect, Active, Open-Sent, Open-Confirm, and Established. Among them, Idle, Active, and Established are common states during the establishment of BGP peer relationships. ...

BGP AttributesBGP attributes, also known as BGP route attributes, constitute a set of parameters describing specific BGP routes. BGP can filter and select routes based on these attributes, which are classified into four types:Well-known mandatory: Identified by all BGP devices and must be carried...
On such a DSVPN network, mGRE tunnels between spokes are set up in shortcut mode. On a DSVPN network, route learning in either mode can be achieved through static route configuration or a dynamic routing protocol (OSPF or BGP). IPsec ...
BGP/MPLS IP VPN uses VPN targets to control VPN routes advertisement. A VPN instance is associated with one or more VPN target attributes. VPN target attributes are classified into the following types: Export target: After a PE device learns IPv4 routes from directly connected sites, it conve...

BGP makes best-path decisions based on attributes that include the following: Highest weight. Current reachability. Hop counts. Local preference. Oldest path. In situations where multiple paths are available -- as within a major hosting facility -- BGP policies communicate an organization's preferenc...
You can configure the BGP attributes in your NVA and let Azure Route Server know which NVA instance is active or passive (you can use active-active for performance or active-passive for resiliency). The interface between NVA and Azure Route Server is based on a common standard protocol. As ...
