Disable Next-Hop Processing on BGP Updates
Perform this task to disable next-hop calculation for a neighbor and insert your own address in the next-hop
field of BGP updates. Disabling the calculation of the best next hop to use when advertising a route causes
all routes to be advertised with the network device as the next hop.
Next-hop processing can be disabled for address family group, neighbor group, or neighbor address family.Note
