RHEL 7 hosts never expire ICMP Redirect route cache entries
Issue
-
RHEL 7 hosts which have received an ICMP Redirect never expire the entry from their route cache. Further, the cached entry is not visible using the normal tools. It is only visible using
ip route get.# ip route show cache | wc -l 0 # cat /proc/net/rt_cache | wc -l 0 # ip route get 10.20.30.10 10.20.30.10 via 192.168.100.10 dev eth1 src 192.168.100.113 cache <redirected>
