I ve a doubt in Route Aggregation with MPLS Label generation...
Suppose i have the following connectivity:
R4 is having two connectivity one to R5 and R6 and aggregates the two Customer subnets into Single Subnet... For eg..
R4 aggregates two CE subnets into 10.10.0.0/22 and giving it to R1, R2 & R3.
As far as my understanding...
R4 will have the LFIB entry as Aggregate so that it looks into its Routing Table for sending the packets to either of the CE.
SO what would be the label value R4 generates and gives to R1,R2 and R3... Because in R4'r routing entry has two /24 but in R1,R2 and R3 routing entry has one /22.... (Will R3 and R4 exchange the labels since both the routers have different prefix lengths)..
How the labels are generated and exchanged between the routers and how the traffic is flowing with labels prepended..
Thanks in advance...
