افتراضي RT and RD


Hi to All,

Any body who is exposed to VRF-Lite, RD and RT i need your help in understanding the concepts about them. Here are my concerns:

- RD : is used to hide the ip address of one customer, if another customer is using the same ip address..right? can the value of RD for customer A be the same RD value for customer B..example { IP vrf customer-A , RD 1:1} and { IP vrf customer-B, RD 1:1}
or it has to be different so the router would know which is which?


- RT : this is used with import and export..right?...and the value for the import is the same value that the customer is exporting and the export value that we are exporting should be the value of import that the customer is importing...example:

IP vrf customer-A
RT import 1:9999...the customer should use the value that am exporting for some routes
RT export 1 :1000


our network

IP vrf customer-A
RT import 1:1000.....i will use the value that the customer is exporting for some routes.
RT export 1:9999


im not sure if i get it or im just confused, can someone explains it to me like a baby with some examples.?

and for the MPLS do we have to use BGP protocol with it or we can use a different IGP?
