HPE FlexNetwork HSR6800 Configuration Manual page 255

On Router B, establish an EBGP connection with Router A and an IBGP connection with Router C;
configure BGP to advertise network 9.1.1.0/24 to Router A, so Router A can access the intranet through Router
B; configure a static route to interface loopback 0 on Router C (or use a routing protocol like OSPF) to establish
the IBGP connection.
On Router C, establish an EBGP connection with Router A and an IBGP connection with Router B;
configure BGP to advertise network 9.1.1.0/24 to Router A, so Router A can access the internal network
through Router C; configure a static route to interface loopback 0 on Router B (or use another protocol like
OSPF) to establish the IBGP connection.
