BGP Administrative Distance As you know routing protocols have Administrative Distance values for preferability.And different vendors have different AD values for the same routing protocols.This is also valid for BGP. Some main vendors and BGP AD(Preference) Values are below: Cisco => 20(eBGP) and 200(iBGP)200 Juniper => 170 Alcatel-Lucent => 170 In Cisco routers two AD […]

bgp (border gataway protocol) ibgp (internal BGP) ebgp (external BGP)

BGP Peers, BGP Sessions and BGP Messages What is BGP peer? To use BGP, the neighbourship between the BGP routers must be established. You can use the statement BGP neighbour or BGP peer for this establishment. There are two types of BGP peer. These are iBGP(interior BGP) peer and eBGP(exterior BGP) peer. iBGP peer is […]
