When configuring an iBGP session, use/configure the other router's loopback address.The following are best practices for BGP and addressing: If the router only has one physical interface or one path to it's neighbor(s), using a loopback doesn't provide any further stability. Yes, the above statement is appsolutely correct and BGP peering with Loopback address is a best idea.Р В РІР‚СњР В РІР‚С›ssuming the router has multiple physical interfaces or paths to which the loopback can be reached. If this answered your question please click on correct answer. If a loop is configured, the RID will be the highest loop address.' unless a loopback interface has been configured. The main reason for using a loop-back on a switch as the management address is that it would fall in line with a simple policy 'we always use lo0 as management, lo1 - 9 as tunnel end points' sort of thing, and there is no need to modify the policy for routers or switches, and standard security configs may be a little easier.Р В РІР‚СњР вЂ™Р’В¬oming to Loop-back address in OSPF 'The RID will be the highest physical interface on the router. The thinking behind that is that if there is any way to your router you can get to the loop-back - if you used a real interface address if that was the interface that was down, you would lose access. It has long been recommended that a loop-back address be used for management on routers. Vlan interfaces are generally used for management on switches and Loop-backs are often used for management on routers.
