If you configure a static IPv6 route using an egress interface and 
enter the ping command to reach the destination IPv6 address, the 
ping operation may not work. Configure the IPv6 route using a next-
hop IPv6 address in order for the 
ping command to detect the 
destination address.
ipv6-address
(OPTIONAL) Enter the forwarding router IPv6 address in the x:x:x:x::x 
format.
NOTE: The :: notation specifies successive hexadecimal fields of 
zeros.
distance
(OPTIONAL) Enter a number as the metric distance assigned to the 
route. The range is 1 to 255.
tag 
value
(OPTIONAL) Enter the keyword tag followed by a tag value number. 
The range is 1 to 4294967295.
permanent (OPTIONAL) Enter the keyword permanent to specify that the route 
is not to be removed, even if the interface assigned to that route goes 
down.

associated with the keyword permanent, the route disappears 
from the routing table.
