Conditions: This symptom is observed when you enter the ip nat pool name 192.168.22.100
192.168.22.120 netmask 255.255.255.0 command. When you do so, the output of the show
running-config command shows the above-mentioned command and, in addition and unexpectedly,
also the ipv6 nat v6v4 pool name 192.168.22.100 192.168.22.120 netmask 255.255.255.0

Symptoms: Routes may be unexpectedly removed from the routing table.
Conditions: This symptom is observed when IS-IS is used to advertise IP prefixes and when you
enter a distance command that changes the overall configuration but keeps a subset of the prefixes
at the same distance as in the previous configuration. The routes for which the distance does not
change may be removed from the routing table.
enter a distance command that changes the overall configuration but keeps a subset of the prefixes
at the same distance as in the previous configuration. The routes for which the distance does not
change may be removed from the routing table.
The following two examples show configurations in which the symptom occurs. When the distance
configuration for IS-IS is 115 ip and you enter one of the following command sequences, the
symptom occurs:
