# In BGP view, perform MD5 authentication on the TCP connection set up between the
local router 10.1.100.1 and the peer router 10.1.100.2.

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 value.
The default preferred value is 0.

Among multiple routes that have the same destination/mask and are learned from
different peers, the one with the biggest preferred value is selected as the route to the
network.
