Routing

Hi,

 

In my routing table I am receving 0/0 route from two ISP peers and one is only active. And all my network trafffic is passing through active route. Now i want to advertise some subnets to ISP2 peer as per daigram attached. what changes required to do load balancing it.

The default route is being used for outgoing traffic.

 

What do you want to loadbalance here? incoming or outgping traffic ?

i want to use it for outgoing traffic. And I have advertised equally all prefixes in to both ISPs.

Ok..in that case alongwith what vincy has mentioned, you need to configure per-packet loadbalancing as well. You can refer to below docs

https://www.juniper.net/documentation/en_US/junos/topics/topic-map/bgp-multipath.html

 

Put the peering to both ISP1 AND ISP2 under a single/same group and use the below knob "multipath multiple-as"

Both the 0/0  routes will be active 

set protocols bgp group xx multipath multiple-as 

 

 

If this worked for you please flag my post as an "Accepted Solution".

Thanks for your reply. Let me try this option and update you.
