Step 2: Install the tunnel.sh, or manually create the appropriate GRE tunnels. You should be able to ping the provided peering IP (ours) over this GRE tunnel. Step 3: The term "BGP Route Reflector" refers to a BGP implementation that redistributes routes between iBGP peers RFC4456. When using bagpipe-bgp on more than one compute node, we thus need each instance of BaGPipe-BGP to be configured to peer with at least one route reflector (see Configuration ).AWS Transit Gateway Connect Plugin. The 128T-aws-transit-gateway-connect plugin provides integration between a 128T and a Transit Gateway.
