Hi all, Two more questions, does it still make sense to get adv. sec license for MX if its in one-armed concentrator mode in DC since DC would have its security devices? Also with once-armed concentrator mode, iBGP is enabled on the tunnels. If we use OSPF between MX in one-armed concentrator mode and the upstream device (switch) is there an automatic redistribution between iBGP and OSPF. I understand MX can advertised OSPF routes but cannot learn them. Thanks, Aamir
