my network is actually a MPLS VPN circuit.in this we are actually using OSPF in the back bone.but the clients which are connected to this network is having private ips.so in this vrf is also playing a key role.can u try to xplain how these vrf route table is updating and all..???
this is a long story. VRF is like a virtual/configured router with its own interfaces, routing processes and forwarding tables.
Routing wise in a MPLS VPN environment between PE routers MP-BGP is used and routes are made unique with the help of a route-distinguisher. So two customers with each 10.0.0.0/24 will be seen as different prefixes inside MP-BGP, f.e.
The above noted prefixes are called VPNv4 addresses (96 Bit long).
To setup a rule set where those prefixes should be visible, i.e. in which VRF they should be imported, route-targets are used.
They define VPN membership. This is like a person (VPNv4 prefix) who is member of f.e. Chicago Bears fan club (RT 1) and also member of the Dallas Mavericks fan club (RT 2). A prefix may be found in several VPNs.
Hope this helps a bit. If not, go ahead and ask more detailed questions, you are welcome.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
