difference between virtual and secondary interfaces
hello,
Can someone tell me the difference between virtual and secondary interfaces/ip addresses. Thanks in advance. Thanks fundoos |
The term "virtual IP" typically means the same as aliased IP. On GNU/Linux, when you create an alias IP, it gets an alias interface assigned to it, which I presume would also be called a "virtual interface". The convention for alias interface names is to use the name of the real interface, followed by a colon and then an integer. Here's an example of what it looks like on my box to set up an alias:
Code:
win32sux@candystore:~$ ifconfig |
Quote:
Code:
$ ip addr show |
a virtual interface could also apply to a virtual network used by a virtual machine such as vmware to provide a network presence for the virtual machine, this way the virtual machine can access any lan/internet features that the real machine has, another example of a virtual interface would be one vor a VPN (such as hamachi) tho this could be argued to be an alias on the real nic, virtual interfaces usually have their own separate ip address.
