Static Route ECMP Monitoring upstream

Hi All, 

 

Probably a quick question. I am attempting to implement ECMP with two static routes. Such as:

 

ECMP on

e1/1 = 192.168.255.9/29

route 10.0.0.0 255.255.255.0 192.168.255.11

route 10.0.0.0 255.255.255.0 192.168.255.12

 

My question is, if 192.168.255.11 is unavailble, will the PAN remove that route as a vaiable route? Or do I have to use a dynamic routing protocol like ospf to protect against traffic being routed to a router that doesn't exist.

ECMP Dynamically shift traffic to another ECMP member to the same destination if a link fails, rather than having
to wait for the routing protocol or RIB table to elect an alternative path/route.

Both next-hop destinations share the same VLAN, so does PAN rely solely on the PAN's interface link state(e1/2 UP/DOWN) or does it check each next-hop via a ICMP ping or something?

You have to use dynamic routing protocol, there is no ping check with ECMP yet in 7.0.X.

With ECMP, the route will be withdaw only if the interface state goes down.

Correct me if I'm wrong.
