internet failover setup

[vicky.dhas]

Dear Friends ,

Please give your solution

I have mpls-vpn connection and internet connection from same service provider.Both links are terminated on the same router.

Inerface hand off is Ethernet in both cases

Now I want to configure a seperate Internet access using same vpn last mile but which should act as a back up for my existing internet connection.Service provider can deliver internet and mpls vpn using same last mile(different VLAN+VRF configuration).What are the configuration changes need to be done for this set up.

do i need to run dynamic routing protocol to configure fail over?

any other option without using dynamic protocol

pl suggest.

thanks

what you need to learn is floating static routes and how they are binded with IPSLA/SAA objects.

what you need to do is create static default routes pointing to differnet outgoing interfaces and to add automation and intelligence use IPSLA/SAA.

Hope this help.

If you can share your configs i can be a bit precise.

you can use two default static routes ( if you are using it already ) but with IPSLA tracking

for example

ip route 0.0.0.0 0.0.0.0 IS1!_NEXT_HOP track 1

ip route 0.0.0.0 0.0.0.0 ISP2_NEXT_HOP  10 -- with higher metric

now if the track has been configured for example to pin ISP 1 every 30 seconds once the ping fail for exampel for 3 attempts the first default route will disapear forom therouteing table and the next one with higher metric will take effect using the other link next hop

also the bellow document has some examples and tricks might help you to configure it
