GRE tunnel configuration – DMF/BMF

DMF support L2-GRE tunneling, to transmit/receive encapsulated monitoring traffic over a network. This feature can be used to extend a DMF deployment across multiple data centers or branch offices over networks connected by Layer 3 networks. This supports centralization or distribution of tools and taps/spans across multiple locations when they cannot be directly connected.   Scenario 1: Using GRE tunnel as a core interface. For core links, the direction of the tunnel should be bidirectional and encap loopback interface is required. Both endpoints will periodically transmit LLDP frames, and DMF will discover that the tunnel is a core link. The...
