Injecting a local network

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

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

control route advertisement. The network to be injected must be available in the local IP routing table.
To inject a local network:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter BGP view.

bgp as-number

N/A

3.

Inject a network to the BGP
routing table.

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

route-policy-name

Optional
Not injected by default

Configuring BGP route redistribution

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.
To configure BGP route redistribution:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter BGP view.

bgp as-number

N/A

3.

Enable route redistribution
from a routing protocol into

BGP.

import-route protocol [ { process-id
| all-processes } [ allow-direct |

med med-value | route-policy

route-policy-name ] * ]

Not enabled by default.
The allow-direct keyword is

available only when the specified
routing protocol is OSPF.

NOTE:

Only active routes can be redistributed. You can use the display ip routing-table protocol command to
display route state information.

Enabling default route redistribution into BGP

Using the import-route command cannot redistribute a default route.
To enable default route redistribution into BGP:

Step Command
