BGP Weight Route / Prefered Route

[WebToor]

Hi,

How i can modify weight route from :

show ip route

To configure prefered route, or this is not the good way to configure prefered route.

If a check documentation i can see different way to modify route :

https://docs.vyos.io/en/equuleus/configuration/protocols/bgp.html

1. Weight checkPrefer higher local weight routes to lower routes.
2. Local preference checkPrefer higher local preference routes to lower.
3. Local route checkPrefer local routes (statics, aggregates, redistributed) to received routes.
4. AS path length checkPrefer shortest hop-count AS_PATHs.

Thanks.

I recommend to use “local-preference”
You need create a prefix-list (not necessary) , route-map
set desired “local-pref” for match prefix-list
Permit/deny others prefixes
Attach route-map to neighbor for “import”
