Setting 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 set a preferred value for routes from a peer or peer group (IPv4 unicast/multicast address family):
Step | Command | Remarks |
|---|---|---|
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. |
| N/A |
3. Set a preferred value for routes received from a peer or peer group. | peer { group-name | ipv4-address [ mask-length ] } preferred-value value | The default preferred value is 0. |
To set a preferred value for routes from a peer or peer group (IPv6 unicast/multicast address family):
Step | Command | Remarks |
|---|---|---|
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 view. |
| N/A |
3. Set a preferred value for routes received from a peer or peer group. | peer { group-name | ipv6-address [ prefix-length ] } preferred-value value | The default preferred value is 0. |
