Appropriate IGP or static route is also required to configure in
order to reach non-directly connected interfaces.
Refer to below procedure for multi-hop configuration on ZTE
ZXR10 GER.
Router Command Line Interface has been accessed.
BGP is running on a network.
1. To set up an EBGP neighbor on a non-directly connected
interface, the multihop command needs to be used to
complete EBGP multi-hop configuration in BGP route mode.
This is shown in
Table 287.

This configures EBGP
multi-hop
Result: This sets EBGP multi-hop for non-directly connected
interface.
END OF STEPS
Example: As shown in Figure 97, router R1 needs to set up
adjacency on a non-directly connected interface (with the IP
address of 180.225.11.1) of R2. In this case, the multihop
command needs to be used.
