I have 2 links from thesame isp. So segments are divided between the links and advertise using prefix-list for restriction
Now one of the link is having issues, so i decided to send all the traffic on the other link, but i realise that since there is no restriction the faulty link while the bgp is still up, all the segments inside the bgp session are advertise there because BGP is still up, now looking like there is a look, i thought of using advertise map at the level of the neighbor but recieve only a BGP default route from my upstream.
I cant shut BGP down because my neighbor ip addresss comes through BGP and my IPSEC GRE tunnels use this ip address
What else can i use in other to restrict this
