I am using an MPLS circuit to connect to each site. Do I need the IP address for the MPLS device at each site? Currently the MPLS at each site is connected to a switch which is using a port that connected to the VOIB board. The ip addresses I listed above were:

System A, I have the KSU Ip address 192.168.1.30, The VOIB card is 192.168.31.

System B KSU IP address 192.168.2.33, VOIB card is 192.168.2.34
