- Currently OmniAccess 5740 USG supports DMVPN interoperability with Cisco IOS

that has NHRP phase 3 implementation (like Cisco IOS Version 12.4(24)T2, Version

tunnel for DMVPN.
• Supports unicast forwarding on DMVPN tunnels. Supports BGP (Border Gateway
Protocol) over DMVPN tunnels.

unless specified.
• There is no softlimit on mGRE tunnels.
