I have a multi-path (all MT) network using OSPF routing and I'm trying to get the Redistribute Default Route function to work properly when set to "if installed". Everything works fine if I set it to "always (as type 1)", but not when I change it to "if installed (type 1)". Using the Type 2 variant yields the identical result. When set to "if installed" it thinks the interface is down and it stops advertising. When I switch it back to "always" it comes back up. There's nothing wrong with the Internet connection and this is the edge router. I tried enabling/disabling the "Check gateway" feature but that didn't help.
I have 2 Internet connections in 2 different facilities and I want Internet traffic to failover to the working connection when the local connection fails (i.e. using the check gateway feature). The default redistribution works great when I flip it manually, but I can't figure out why the if-installed function is not work the way I expect it to.
Thanks,
