Redistributing IGP routes
Perform this task to configure route redistribution from an IGP to BGP.
By default, BGP does not redistribute default IGP routes. You can use the default-route imported
command to redistribute default IGP routes into the BGP routing table.
Only active routes can be redistributed. To view route state information, use the display ip
routing-table protocol or display ipv6 routing-table protocol command.
The ORIGIN attribute of BGP routes redistributed from IGPs is INCOMPLETE.
To configure BGP to redistribute IGP routes (IPv4 unicast/multicast address family):
1. Enter system view.
system-view
N/A
2. Enter BGP IPv4 unicast
address family view,
BGP-VPN IPv4 unicast
address family view, or BGP
IPv4 multicast address family
view.
• Enter BGP IPv4 unicast
address family view:
a. bgp as-number
[ instance
instance-name ]
b. address-family ipv4
[ unicast ]
• Enter BGP-VPN IPv4 unicast
address family view:
c. bgp as-number
[ instance
instance-name ]
d. ip vpn-instance
vpn-instance-name
e. address-family ipv4
[ unicast ]
• Enter BGP IPv4 multicast
address family view:
f. bgp as-number
[ instance
instance-name ]
g. address-family ipv4
N/A
3. Enable route redistribution
from the specified IGP into
BGP.

By default, BGP does not
redistribute IGP routes.
4. (Optional.) Enable default
route redistribution into BGP.
default-route imported
By default, BGP does not
redistribute default routes.
To configure BGP to redistribute IGP routes (IPv6 unicast/multicast address family):
1. Enter system view.
system-view
N/A
2. Enter BGP IPv6 unicast
address family view,
BGP-VPN IPv6 unicast
address family view, or BGP
IPv6 multicast address family
• Enter BGP IPv6 unicast
address family view:
a. bgp as-number
