The ExaBGP implements a BGP adaptor of kinds, enabling third-party applications to interface with the network's BGP mesh in order to glean information and also to instruct the network through routing information. It is capable of speaking many of the multi-protocol address families supported by BGP, but the only address family required in this case is IPv4-flow and IPv6-flow.
The flow sub-type of the address family is denoted within protocol terms as a Subsequent address family identifier (SAFI) and is assigned a code. Vanilla unicast IPv4 makes use of SAFI 1, whereas flow-spec IPv4 makes use of SAFI 133.
We establish a BGP topology that connects our ExaBGP management host with our JUNOS OS routers. In our case, this is a ...
