I need please an experienced person who can help me validate this configuration for the following scenario: 2 MPLS circuits (primary and secondary) configured for active/active. I need guidance on implementing failover between the circuits using MED and local preference, or if you have a better configuration suggestion.
Configure interfaces for MPLS circuits
interface TenGigabitEthernet0/0/0
description Primary MPLS Circuit
ip address 200.0.110.2 255.255.255.252
interface GigabitEthernet0/0/0
description Secondary MPLS Circuit
ip address 195.30.90.2 255.255.255.252
! BGP configuration for primary MPLS circuit
router bgp 65000
bgp log-neighbor-changes
network 192.168.10.2 mask 255.255.255.0
neighbor 200.0.110.1 remote-as 65100
neighbor 200.0.110.1 description Primary MPLS Neighbor
!
address-family ipv4
neighbor 200.0.110.1 activate
neighbor 200.0.110.1 send-community both
neighbor 200.0.110.1 route-map PRIMARY-OUT out
neighbor 200.0.110.1 route-map PRIMARY-IN in
neighbor 200.0.110.1 soft-reconfiguration inbound
exit-address-family
! BGP configuration for secondary MPLS circuit
router bgp 65000
neighbor 192.168.10.1 remote-as 65200
neighbor 192.168.10.1 description Secondary MPLS Neighbor
!

neighbor 192.168.10.1 activate
neighbor 192.168.10.1 send-community both
neighbor 192.168.10.1 route-map SECONDARY-OUT out
neighbor 192.168.10.1 route-map SECONDARY-IN in
neighbor 192.168.10.1 soft-reconfiguration inbound
exit-address-family
! Route maps for BGP attribute manipulation
! For Primary Circuit (2Gig)
route-map PRIMARY-IN permit 10
set local-preference 200
set metric 100
Thank you.

check this
and friend config LP effect outbound traffic
config MED dont do anything if SP or other site use route-map to control inbound traffic to your site

sorry I make you waiting
you have one Hub dual ISP and connect to MPLS Core
if that correct then I will run lab and share it today with you

No worries thank you much.
yes we have one hub dual ISP and connected to the spokes site via MPLS
