How to balance traffic in MPLS BGP in Hub spoke conectivity.

[nagar.aashish091]

Hi Freinds, Hope you are doing well.

I have concern in manage traffic in MPLS BGP link. Just explaing below

We have Two Hub location and 20 spoke location.All spoke location and hub location connected through ISP via MPLS BGP(EBGP).Spoke location user use internet through hub location becouse we have internet connection at only hub location.We just want to divide some spoke location use in/out internet traffic throug HUB 1 and some spoke location use in/out internet traffic through Hub2 and also if one of hub down then all spoke use another hub.All hub and spoke have same private as number.

you advertise default route into all Spokes, do you use Peer group and listen ?
if Yes use two group and advertise to each group default route with different MED
this make group A have default route via Hub1 and group B have default route via Hub2 both group have two path to default in bgp 
one for each Hub

Is this Hub and Spoke - using any VPN technologies, just MPLS connectivity ?

You can use preferred path based on the different methods :

Hello,

You must be receiving default route in Spokes. Use higher weight for default route for preferred HUB and lower weight for less preferred HUB.

Advertise prefixes from spoke with longer/short  prepend for less preferred / higher preferred. This gives you symmetric path.
