BGP influence outbound traffic based on prefix I have two router `core1` and `core2` connected with ISP router border1 and border2 using `eBGP` peer and i have 5 public subnect (/24). My ISP sending me default route instead of full BGP table. Question: I have 5 public IP subnets (prefix) and now i want 3 prefix traffic go out from `core1` and remaining 2 subnet traffic go out from `core2` and bore core1/2 connected over iBGP so how do i influance outgoing traffic using local-pref? (we can use AS prepend to inflaunce inbound traffic) How do i create prefix-list to make my first 3 subnet use core1 ? ![enter image description here](

Your post states your ISPs send you default routes only. Therefore, you'll need to configure static routes toward the desired transit provider to direct traffic for the 5 routes of interest to ISP A or B.

Assume `192.0.2.0/24` is a prefix you want to route to the Internet via ISP A which has next-hop address `203.0.113.1`:


route-map redist-to-bgp permit 100
match tag 1
route-map redist-to-bgp deny 9999
!
router bgp 64496
redistribute static route-map redist-to-bgp
!
ip route 192.0.2.0 255.255.255.0 203.0.113.1 tag 1
