ebgp load-sharing on not dual-homed.

Network is connected both AS 100 and AS 200.

When the traffic arrive AS 6500 router, we would like to load balancing the

Traffic both AS 100, and as 200, (remark : it's different AS)

I searched the solution, and I found the 'bgp multipath'

bgp multipath n

bgp multipath ibgp n

bgp multipath eibgp n

What command is needed if we implement the BGP load-sharing on different?

In my thought, the bgp multipath n is solution, because of different as in AS

65500 manner.

But I read the like following.

' if you implement the EBGP load sharing with bgp multipath, you should your

router is connected with dual-home.'

But we are not dual home as you seen the topology.

Re: ebgp load-sharing on not dual-homed.

Hello Sung,

bgp multipath n is part of the solution but it is not enough.

an additional hidden command is needed to make the router install routes from the two different ISPs with a different peer ASN.

try to search bgp bestpath as-path multipath-relax in the forums

bgp bestpath as-path multipath-relax

see
