Systems and/or methods of secure communication of information between multi-domain virtual private networks (VPNs) are presented. A dynamic group VPN (DGVPN) can reside in one domain and a disparate DGVPN can reside in a disparate domain. An administrative security authority (ASA) can be employed in each domain. Each ASA can generate and exchange respective keying material and crypto-policy information to be used for inter-domain communications when routing data from a member in one DGVPN to a member(s) in the disparate DGVPN, such that an ASA in one domain can facilitate encryption of data in accordance with the policy of the other domain before the data is sent to the other domain. Each ASA can establish a key server to generate the keying material and crypto-policy information associated with its local DGVPN, and such material and information can be propagated to intra-domain members.
