BGP - Load sharing - q

[dpugalendi.d]

My server LAN is – 172.30.1.0/24 , and using BGP for primary and secondary Links on a single HUB Router,

I need to Load share the secondary Link by specific ip address ,

172.30.1.5 and 172.30.1.6 server traffic only via the Secondary Link using BGP on Router.

Note : When secondary is down it should use primary Link for all my spoke sites

Need help what to change on HUB and spoke Router BGP configs

Can i do the same on HUB and Spoke - both using PBR  , is it makes any difference...
