hi,
I am a beginner in networking area, while reading about the BGP rules i came to know about the longest prefix match.in this regard, i thought if we have:
138.39/16 / ISP3 \ 138.39.1/24
/ \
/ \
ISP1 _____P2P_____ISP2 138.39.1/24
138.39/16 \ /
\ /
CUSTOMER
138.39.1/24
i saw these slides online while doing search for BGP. according to this figure ISP3 will send the traffic to customer thru ISP2 due to the longest prefix match rule.ofcourse, ISP1 and ISP2 both are providers of the customer. i want to ask that if the network route thru ISP2 becomes congested or have higher load, but since due to the longest prefix match ISP3 will still send data through ISP2, how can the load be balanced in this situation?
i found a solution to this which says split the prefix in two, to balance the load. would that work?
can there be some other way to balance the load while keeping the BGP rules valid??:\:\
