Interoperability of MPC10E with MX-SPC3 for IPSec services steering

The MPC10E-15C-MRATE and MPC10E-10C-MRATE interoperates with the MX-SPC3 card to enable the packet forwarding path that steers packets to the MX- SPC3 card. The MPC10E line card can perform the ingress or the egress processing for IPSec services packets through the st0 and vms interfaces, nexthops, and the routes programmed in the line card.
