Command Manual – IPv6 Routing
H3C S7500E Series Ethernet Switches Chapter 5 IPv6 BGP Configuration Commands
5-42
Parameters
ipv6-group-name: Name of a peer group, a string of 1 to 47 characters.
ipv6-address: IPv6 address of a peer.
value: Preferred value, in the range 0 to 65535.
Description
Use the peer preferred-value command to assign a preferred value to routes received
from a peer or peer group.
Use the undo peer preferred-value command to restore the default.
By default, routes received from a peer or peer group have a preferred value of 0.
Routes learned from peers each have an initial preferred value. Among multiple routes
to the same destination, the route with the biggest value is selected.
Note that:
If you both reference a routing policy and use the command peer { ipv6-group-name |
ipv6-address } preferred-value value to set a preferred value for routes from a peer,
the routing policy sets a non-zero preferred value for routes matching it. Other routes
not matching the routing policy uses the value set with the command. If the preferred
value in the routing policy is zero, the routes matching it will also use the value set with
the command. For information about using a routing policy to set a preferred value,
refer to the peer { ipv6-group-name | ipv6-address } route-policy route-policy-name
{ import | export } command and the apply preferred-value preferred-value
command.
Examples
# Configure the preferred value as 50 for routes from peer 1:2::3:4.
