Figure 1-18 Next hop attribute configuration 

 

 

Note that: if you have configured BGP load balancing on a BGP router, the router will set it as the next 

hop for routes sent to an iBGP peer/peer group regardless of whether the peer next-hop-local 

command is configured.  

Follow these steps to configure the next hop attribute: 

Enter system view 

— 

Enter BGP view 

bgp as-number 

— 

Specify the router as the next hop of 
routes sent to a peer/peer group 

peer { group-name | 
ip-address } next-hop-local 

Optional 

By default, the router sets 
it as the next hop for 
routes sent to an eBGP 
peer/peer group, but 
does not set it as the next 
hop for routes sent to an 
iBGP peer/peer group. 

 

In general, BGP checks whether the AS_PATH attribute of a route from a peer contains the local AS 

number. If so, it discards the route to avoid routing loops. 

This task allows you to permit local AS number to appear in routes from a peer/peer group and specify 

the appearance times. 

Enter system view 

— 

Enter BGP view 

bgp as-number 

— 

Permit local AS number to appear in 
routes from a peer/peer group and 
specify the appearance times 

peer { group-name | 
ip-address } allow-as-loop 
[ number ] 

Optional 

By default, the local AS 
number is not allowed. 

 

Follow these steps to disable BGP from considering AS_PATH during best route selection:
