Specifying a preferred value for routes received
Perform this task to set a preferred value for specific routes to control BGP path selection.
Among multiple routes that have the same destination/mask and are learned from different peers, the one with the greatest preferred value is selected as the optimal route.
To specify a preferred value for routes from a peer or peer group (IPv4):
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter BGP view or BGP-VPN instance view. |
| N/A |
3. Enter BGP IPv4 unicast address family view or BGP-VPN IPv4 unicast address family view. | address-family ipv4 [ unicast ] | N/A |
4. Specify a preferred value for routes received from a peer or peer group. | peer { group-name | ip-address } preferred-value value | The default preferred value is 0. |
To specify a preferred value for routes from a peer or peer group (IPv6):
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter BGP view or BGP-VPN instance view. |
| N/A |
3. Enter BGP IPv6 unicast address family view or BGP-VPN IPv6 unicast address family view. | address-family ipv6 [ unicast ] | N/A |
4. Specify a preferred value for routes received from a peer or peer group. | peer { group-name | ipv6-address } preferred-value value | The default preferred value is 0. |
