Hi,
Tagging routes can help to ease administration especially if the routes need to be re-exported / re-distributed.
It also comes handy when you want to manipulate dynamic routes [Import / Export] etc.
Example:
routing-options {
static {
route 10.10.10.0/24 {
next-hop 192.168.1.1;
tag 110;
}
route 10.20.20.0/24 {
next-hop 192.168.2.1;
tag 90;
}
}
}
policy-options {
policy-statement EXPORT-BGP-LOCAL-PREF {
term PREF-110 {
from {
protocol static;
tag 110;
}
then {
local-preference 110;
accept;
}
}
term PREF-90 {
from {
protocol static;
tag 90;
}
then {
local-preference 90;
accept;
}
}
}
}
Cheers,
