Hi all,
Please see my attached diagram.. where I am advertising 10.0.12.0/24 on R1
and R2.
Assume R1 and R2 are ISP
and R3 and R4 are customer routers
on R3... I want to divert the internal traffic to R4 using weight...but
even after clearing session so many times.. BGP next hop still points to
R1..
I even used local pref on R4...but still doesnt work...is there anything
wrong in my config...or I m missing any step..!
R3#sh ip bgp
BGP table version is 2, local router ID is 10.0.35.3
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
