Routing

Hello Can someone help me in qualified hop concept and example.

[edit routing-options]
user@router# show
static {
defaults {
metric 10;
preference 10;
}
route 10.10.10.0/24 {
next-hop 192.168.100.1;
qualified-next-hop 192.168.200.1;
preference 6;
}
metric 8;
}
}

In above example what will be the next hop for 10.10.10.0/24 will it be 192.168.100.1 or 192.168.200.1. As per my understanding it should be 192.168.100.1 because of the preference value of static route is 5 and in this filter for NH 192.168.200.1 the preference value is set to 6. So lower preference should be preferred. But as per one of book it should be 192.168.200.1. Please explain

2. Example

[edit routing-options]
user@router# show
static {
route 0.0.0.0/0 {
next-hop 10.1.1.1;
qualified-next-hop 10.1.1.254 {
preference 4;
}
}
}

In this example the next hop should be 10.1.1.254 please correct if i am wrong.

Thanks!!

It's correct for the first example. By default, a static route has a preference of 5.

However, you are altering the default setting for the static routes anc configure a preference of 10.

The qualified next-hop has a pref of 6 and it's chose as next-hop.

In the second example, you are using the default settings for static routes(preference of 5), which is higher than 4, the preference of the qualified next-hop, so the qualified next-hop is used.
