per topology and on the site#1 to site#2 migration strategy later in year. First, I want to integrate both Rx-PR into IBGP with site#2 under AS 30 so will have the same AS in 2 locations. There is a redundant WAN btwn the two sites. Currently, both ISP are sending default route to site#2 but I plan to do EBGP with them. My plan is that during cut night, I am getting rid of isp#2 but keeping isp#1 and will have isp#1 move the 22.214.171.124/24 over to site#2 or preferably can I have site#2 also advertise 126.96.36.199/24 with a lower/highter metric (ie Prepend AS) so during the cut, I don’t have to do much but just turn off site#1 internet routers.
I have this problem too.
