Why so many loopback addresses on single router? What purpose will it solve?I
Loopback addresses are useful in various configurations of routers. These include:
- the use as a router ID for dynamic routing protocols such as EIGRP and OSPF
- the use as the location from which BGP peering takes place, especially when creating multiple links between routers
- for testing and diagnosis purposes
Loopbacks should only be created when necessary, if there’s no reason to have them, then there’s no reason to create them.
I hope this has been helpful!
