Use the network command to inject a network to the local BGP routing table.  

Use the undo network command to remove a network from the BGP routing table. 

By default, no network route is injected. 

Note that: 

z 

The network route to be injected must exist in the local IP routing table, and using a routing policy 

makes route management more flexible. 

z 

The ORIGIN attribute of the network route injected with the network command is IGP. 

# In BGP view, inject the network segment 10.0.0.0/16.

# In BGP-VPN instance view, advertise the network segment 10.0.0.0/16 (the VPN has been created).

ip-address: Destination IP address. 

mask: Mask of the network address, in dotted decimal notation. 

mask-length: Mask length, in the range 0 to 32.  

Use the network short-cut command to configure an eBGP route as a shortcut route.  

Use the undo network short-cut command to restore the default. 

By default, a received eBGP route has a priority of 255. 

The network short-cut command allows you configure an eBGP route as a shortcut route that has the 

same priority as a local route and thus has greater likehood to become the optimal route.
