Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. The protocol was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers. Functionality of EIGRP was converted to an open standard in 2013 and was published with informational

Some vendors have a preference (distance) of 20 for external BGP (EBGP) and a distance of 200 for internal BGP (IGBP). Junos OS uses the same value (170) for both EBGP and IBGP. However, this difference between vendors has no operational impact because Junos OS always prefers EBGP routes over IBGP routes.

eBGP Topology: It does not require full mesh neighborship. eBGP TTL: By default Apr 3, 2020 Administrative distance is the first criterion that a router uses to determine which routing protocol to use if two protocols provide route information It makes things kinda weird - for example iBGP administrative distance is 200, so a learned route can actually bomb a connected route which is probably not Direct.

To change the default administrative distances for EBGP, IBGP, and Local BGP4, enter a command such as the following. device (config-bgp-router)# distance 200 200 200. Syntax: [no] distance external-distance internal-distance local-distance. The external-distance sets the EBGP distance and can be a value from 1 through 255.

By default, iBGP peers are set with TTL = 255: AD (Administrative Distance) EBGP routes have administrative distance of 20: IBGP routes have administrative distance of 200: Next Hop attribute: Next hop is changed to local router when it is advertised to EBGP peer by default: Next hop remains unchanged when route is advertised to iBGP peer: Topology

Static routes have a distance of 1 by default, but you can change this by including a distance value at the end of the “ip route …” command. How to change administrative distance in BGP in relations to OSPF Hi guys, I had a kinda hard time getting the administrative distance config working. I was also unable to find any real good information online on the issue. Administrative Distance: Route source: Default Distance: iBGP는 eigrp보다 낮은 AD를 갖게되어, eBGP > eigrp > iBGP 로 경로를 찾아가게 된다. Administrative distance is used to determine the reliability of one source of routing information from another. Some sources are considered more reliable than others; therefore, administrative distance can be used to determine the best or preferred path to a destination network or network node when there are two or more different paths to the same destination from two or more different routing Modification de la distance administrative par défaut du routeur BGP. "distance bgp" permet de modifier les 3 valeurs de distance administrative par défaut : eBGP.
