Hi All,

                 I would like to know if it is possible to create a single FEC for Multiple Prefixes in the routing table and distribute across the domain through LDP (preferably for Down Stream Unsolicited Mode). One case would be when multiple prefixes that can’t be aggregated/super netted (by the egress) follow the same path from ingress LSR to the egress LSR. Will it be same as FEC aggregation? If it is possible then how ingress LSR will know that all such disparate prefixes follows the same path till egress and accordingly classifies all of them into the same LSP.

 

 

Thanks in advance,

 

Pranjal
