Allow the establishment of 
eBGP connection to a non 
directly connected peer/peer 
group 

peer { group-name | 
ip-address } ebgp-max-hop 
[ hop-count ] 

Optional 

Not allowed by default. 

 

The  peer ebgp-max-hop command needs not be configured if the two eBGP peers are directly 

connected. 

 

Different from IGP, BGP focuses on route generation and advertisement control and optimal route 

selection. 

There are to ways to generate BGP routes: 

z 

Configure BGP to advertise local networks 

z 

Configure BGP to redistribute routes from other routing protocols, including the default route 

BGP connections have been created. 

In BGP view, you can inject a local network to allow BGP to advertise it to BGP peers. The origin 

attribute of routes advertised in this way is IGP. You can also reference a route policy to flexibly control 

route advertisement. The network to be injected must be available in the local IP routing table. 

Follow these steps to inject a local network: 

Enter system view 

— 

Enter BGP view 

bgp as-number 

— 

Inject a network to the BGP 
routing table 

network ip-address [ mask | 
mask-length ] route-policy 
route-policy-name 

Optional 

Not injected by default 

 

BGP does not find routes by itself. Rather, it redistributes routing information in the local AS from other 

routing protocols. During route redistribution, you can configure BGP to filter routing information from 

specific routing protocols. 

The origin attribute of routes redistributed using the import-route command is Incomplete. 

Follow these steps to configure BGP route redistribution:
