Creating Backup internet Via WAN link to 2nd office

Hi Guys,

Need some suggestion regarding this issue im having. i've got 3 sites in Sydney, Melbourne and Auckland. for my lab, im just trying to solve sydney and melbourne issue. the topology is below.

Im using eigrp as routing protocol. i've pretty much put all the information in the topology picture, i'll explain it a bit here:

1. i've got 100MB tpg internet from both Sydney and Melbourne
2. i've got 20MB WAN link to Melbourne via TPG MPLS Cloud
3. what i've done for my lab is to put a default route from Melbourne and Sydney router to the Internet
4. From the internet router i've also got 2 static router going to both interface.
5. i've got redistribute static configured in eigrp to propagate the static route.

what i basically want is if i shut down internet interface on either sydney or melbourne router it'll go via the want link to the internet. but its not working with default/static router with internet router. however if i put eigrp on the internet router, it works. but i don't want to put eigrp on internet router. if i put eigrp on the internet router all the traffic goes via internet router as this has more bandwidth.

Any Ideas? Melbourne#sh runBuilding configuration...

Why not put EIGRP on the internet router and adjust metrics accordingly if you don't want everything going that way?

ranti13

i wanted to simulate an ISP as much as I can. In real world i can't do anything with the ISP router. All i can do is point my static/default route to the ISP. thats why.

what im trying to figure out is, when we redistribute static how many hops it can carry that information. if its acts like eigrp it should carry all the way but it isn't.

xnx

Do you have a CCNA by the way? If not you need to nail down the basics first before think about how redistribute routes etc..

ranti13

yeah i do have CCNA, and obviously i've googled before posting. if you know why the static route is not propagating to Internet router when the link between Internet and Melbourne is down let me know.

lincis_aus

How similar is the production network to what you have posted here? By looking at the config it seems like you copy-pasted this from production network gear. Probably not a good idea.

ranti13

no its a Packet tracer lab.
