BGP Traffic Engineering

[kumarmh91282]

Hi All,

Need advice and suggestion on BGP traffic engineering.

Please find the attached topology.

Existing Setup details:  DC and Remote location with 2 different MPLS connections ( EBGP MPLS) as shown in topology

Remote branch will reach out DC for Internet and Server farm

Requirement: 1) All Internet traffic should pass through one MPLS service provider (may be the default preferred link)

                     2) All Server farm traffic between DC and remote location on 2nd MPLS link

Please need your suggestion and guidance on this.

@balaji.bandi  sorry failed to mention the same, the link has to work as failover for each other as well

You do not need fail over if any of the link fails ? other link should use ?

Hello,

this should be fairly easy to set up with e.g. weight or local preference and route maps. What does the topology look like (e.g. do you have two routers at each site, connected through iBGP) ?

@Georg Pauwen  have attached the topology, kindly suggest/guide

i was just complicating by trying to use log of BGP parameters.

Solution:

we just have to use AS path prepend for selected prefix on DC  from CE to PE router out

no need to configure any thing on remote side.

(Assuming Link1 as default primary for all traffic, we need to configure AS path prepend between  on link1 CE for specific subnets which you want to pass through link2 by default)
