Hi,

As far I understood that you need to terminate both MPLS and Internet on single router. You can terminate two connections from different providers on single router....The same setup I have in my environment.

I would suggest you to run (however) BGP on MPLS and OSPF or EIGRP on Internet.
Do you have plans any vpn tunnels on Internet? OR it is just for browsing like that?

Regarding configuration see the below example one:

router eigrp 200
network 10.10.10.0 0.255.255.255
network 10.20.20.0 0.255.255.255

router bgp ***ASno****
no synchronization
bgp log-neighbor-changes
bgp bestpath as-path ignore
network 10.10.10.0 mask 255.255.255.0
network 10.20.20.0 mask 255.255.255.0
neighbor 10.50.50.4 remote-as 6
no auto-summary

As per the above config, the traffic from LAN will take BGP MPLS as primary as per BGP AD and EIGRP path will take as secondary...

Hope the above will help you.

Hi Naidu

i will have 2 routers on the edge.each terminate 2 type of link(mpls and internet)  primary internet link on the first router and the second link from isp 2 at router 2 and it the same for mpls

Hi,

If you have 2 routers at edge then you need to configure HSRP  between them for failover happen.

Hi Naidu

its okay to terminate 2 links(internet and MPLS)  in each router with bgp running?

[Latchum Naidu]

Hi,

You can run only BGP when have Internet and MPLS on single router.

Hi Naidu

in my situation , i have 2 routers each with 2 type of different link , so bgp isnt work here

[Latchum Naidu]

Hi,

As I said you need to run HSRP between both edge routers.
And BGP will work even you have two links on single router.... I have this setup.
BGP run on MPLS and vpn tunnels formed on internet, I just configured default route pointing to internt IPS GW.

Hope the above clear you..

Hi Latchum, I am working on same scenario and want to use BGP over MPLS and EIGRP for Internet circuit  . how you do the tracking of MPLS and Internet Circuit in case of failure? is it possible you can send the config of the router please.
