Hi,
I'm having a weird issue. On my router I have :
ip sla monitor 100
type echo protocol ipIcmpEcho 204.107.90.128 source-interface Ethernet0/0
timeout 4000
frequency 10
ip sla monitor schedule 100 life forever start-time now
ip sla monitor 200
type echo protocol ipIcmpEcho 204.107.90.128 source-interface Ethernet1/0
timeout 4000
frequency 10
ip sla monitor schedule 200 life forever start-time now

What I notice is that they are either BOTH up, or BOTH down at the
same time. Then I noticed the ping times were almost exactly the same!

It should only be this high going over satellite, not wireless.
So I tried a traceroute using "traceroute 204.107.90.128 source e0/0"
and "traceroute 204.107.90.128 source e1/0". I noticed that they both
appeared to take what appeared to be the default route.
Did I follow the directions at http://www.nil.si/ipcorner/SmallSiteMultiHoming/
wrong? Is there something else I need to do to make it go out the
proper interface?
Thanks, Tuc
