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.	Enter BGP view:bgp as-number Enter BGP-VPN instance view: bgp as-number ip vpn-instance vpn-instance-name	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 [ mask-length ] } 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.	Enter BGP view:bgp as-number Enter BGP-VPN instance view: bgp as-number ip vpn-instance vpn-instance-name	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 [ prefix-length ] } preferred-value value	The default preferred value is 0.
