Hi Jason,

I won’t be able to draw a diagram for a couple of hours, but here are the
network paths:



LSUHSC-pS-MEB —> MEB-edge —> MEB-Core —> RCB-Core —> firewall —> RCB-Border
—> LONI —>>>

LSUHSC-pS-CSRB —> CSRB-edge —> CSRB-Core —> RCB-Core —> firewall —>
RCB-Border —> LONI —>>>

Both nodes are ACLes off.


Thank you,
Mohamad Qayoom
