Choosing route for Multihomed BGP

[Defoe]

Hi, I recently got another BGP connection. It is now multihomed.

BGP1v4's ping to a third world country is 10ms with 1gbps.
BGP2v4's ping to the third world county is 300 with 200mbps.

BGP somehow choose to go via BGP2v4 instead of the 10ms connection.
I want to control all traffic to this third world county to use BGP1v4 by default, while BGP2v4 route is only used when the default one is down.

This is my raw config.

AS 99999999
fib-update yes
router-id 1.1.1.2

network 99.99.99.0/23
network 2001:999:999::/48

neighbor 1.1.1.1 {
descr "BGP1v4"
announce all
remote-as 1
local-address 1.1.1.2
}

neighbor 2.2.2.2 {
descr "BGP2v4"
announce all
remote-as 2
local-address 2.2.2.3
}

neighbor 2001:6666:6666:6666::1 {
descr "BGP2v6"
announce all
remote-as 6666
local-address 2001:6666:6666:6666::2
}
