IP SLA or some other configuration

TRACY HARTMANN

I have a layer 3 switch that has two circuits 1 Gig and 1 10 Gig to the same location.  I want to use them as Primary and backup.  We have tried to do this with just a EIGRP routing option but doesn't seem to be taking over correctly.   Could I possible do something with ip SLA which says

 

Interface G01

ip address 10.20.0.1

 

interface Tg01

ip address 10.20.0.5

 

then do a track of 10.20.0.6 the other side of the Ten gig, if it goes away it woud route to the 10.20.0.1

 

I could do a route-map with a next-hop but what would be the best solution?

Hello,

 

an IP SLA is definitely an option.

 

track 1 ip sla 1 reachability

!

ip sla 1

icmp-echo 10.0.0.6 source-ip 10.0.0.5

frequency 5

!

ip sla schedule 1 start-time now life forever

!

ip route 0.0.0.0 0.0.0.0 10.0.0.6 track 1

ip route 0.0.0.0 0.0.0.0 10.0.0.2 200

I am assuming I need to put this on both routers on either side...

 

Hello,

 

does the other side consist of one or two routers ? If it is one router, you can indeed mirror the suggested config.
