Load Sharing - BGP

[Anukalp S]

Hi all,

I have two links to ISPs on one router. They are advertising default route to me. Both ISP are in different AS. I want to share load on both links. I want to configure bgp bestpath as-path multipath-relax command but my router doesnt support it. What i am seeing while configuring it is mention below.

Can anyone pls help me configuring this.

Router(config-router)#bgp bestpath ?

Hello Anukalp,

This is cisco hidden command -> bgp bestpath as-path multipath-relax

You will not see it, but you can use it.

R1(config)#

R1(config)#router bgp 100

R1(config-router)#bgp bestpath ?
