On the list is a cool feature called the logical tunnel interface.</p> <p>So, what am I talking about?  One way to separate traffic on a router is to use virtual routers (VRs) so that you wind up with multiple routing tables on the same router.  This separate traffic, but you will usually (read: always) have a demand to get traffic from one VR to another.  There are a few different way to do that (see rib-group, instance-import, next-table, et al.), but one really cool way to do it is through logical tunnel interfaces.</p>
