Converting from Frame Relay to MPLS confguration help

[dpu]

We are in the process of converting our Frame Relay network over to MPLS and I am hoping someone can give me some basic configuration assistance. I have 10 offices on our FR network and each office has either a 1800 series router or a 2800 series router. The host is currently running a 2800.

I don't know how it works in the USA,but here in Europe it's the ISP that handles the MPLS configuration on their PE (Provide Edge) routers and on the CE customer edge routers they let you use a normal BGP routing out a static route.(Note maybe in the EIGRP or OSPF as well.)Try to contact them,and then let us know what they say.

Regards

Yes, normally the provider will install a router for mpls services. However I have seen CPE installed as well. The main thing is to verify with your provider is the ip scheme and what routing protocols to run.

Can you test the MPLS circuit before cutting off the FR?

two things you will really need is going to be on the serial interface add the encap that they support (usually ppp) and the IP address for that connection.

then there is the BGP portion;

router bgp <as# provided by ISP>
no synch
bgp log-neighbor-changes
network <your lan networks>
neighbor <isp router> remote-as <# usually 7018>
no auto-summary


On your side, it is very easy... the part that can be fun is when you are redistributing between BGP and another routing protocol like EIGRP

Most cases I have seen the provider is just dropping off a fastethernet connection to their router and then you just setup whatever routing protocol you have agreed to with the provider .

Thanks - the ISP did say that they will be handling it mostly in the cloud. They will be installing an Adtran w/ an Ethernet handoff to my Cisco routers.

Just make sure you tell them that you want one of the public IP's assigned to the ethernet port of the ADTRAN (If you have 6 usables from a T1, for example)...

If this is AT&T, you will likely have to specify this (I had to, same setup)...

wierd how they are bringing in a adtran though, why not a T1 off of a smart jack?

T1 comes off the SmartJack, into an Adtran L3 switch, and out to ethernet. Ours is for VoIP. The T1 does terminate at the T1. I could put in my Cisco 3640 with the WIC-1DSU-T1 there, but Qwest owns that circuit...so my Cisco comes off the Adtran.

That is weird, must be a Qwest thing. Just got MPLS from Verizon into my 3625. They provided the configlet though, just had to customize it for my situation.

Don't forget to distribute BGP through whatever routing protocol you're using though. ;-)
