Version 6.8 85 Mediant MSBR
Configuration Guide 14. Virtual Routing and Forwarding (VRF)
14 Virtual Routing and Forwarding (VRF)
VRF is an IP feature that is included in IP network routers, which allows the simultaneous
existence and work of multiple routing tables on a single physical router. This can be
visualized, in general and simple terms, as several logical routers inside a physical one.
Because of this separation to different routing and forwarding tables, this feature allows the
creation of different networks and segments without using multiple devices, creation of
VPNs, and isolation of different network segments for better security due to the fact that no
data is transferred from one VRF to another, and much more.
In addition, to utilize this separation of routing and forwarding tables, many components
and configuration objects can be associated with different VRFs on the same device, such
as physical and logical interfaces, static routes, prefix-lists and routing protocol instances.
On the MSBR's MAIN-VRF by default, BGP, OSPF, RIP services exist. The MSBR
supports up to five additional VRFs. For all additional VRFs, the user can enable up to five
dynamic routing services. For example, if VRF “BLUE” has BGP enabled towards the
WAN and RIP towards the LAN, the other VRFs will have cumulatively only three services
remaining for use.
