I have a Brocade FESX648-PREM I set a static route with the following command:
ip route 188.8.131.52 255.255.255.255 184.108.40.206
Where 220.127.116.11 is my real IP address and 18.104.22.168 is an intentionally incorrect next hop IP.
Since, 22.214.171.124 is an invalid next hop IP, 126.96.36.199 stops pinging immediately.
However, when I clear the route with
no ip route 188.8.131.52 255.255.255.255 184.108.40.206 the 220.127.116.11 still does not ping.
If I follow up with
clear ip route 18.104.22.168 255.255.255.255 the IP again will continue to not ping.
If I run a
show ip route 22.214.171.124, I can see that it is correctly routing to the default gateway.
However, if I
write memory and
reload the switch, then the IP will ping again.
It was suggested to me that I should verify that my
ip-cache entries are not exceeding their
system-max values, but that checked out OK as well:
Total number of IP routes: 64382, avail: 15618 (out of max 80000)
Total number of cache entries: 303
Any ideas why this route is getting "stuck"?
EDIT: I found a workaround. 1. Remove the invalid static route, 2. manually set the correct static route, 3. clear the route set in the previous step. Strange, seems like this should not be necessary. If anyone has any thoughts or suggestions on resolving the core issue, I'd still be very happy to hear them.
