Hi Peiter

Thanks a lot. Now I am clear.

With 12.4(15)T, the IPSec profiles has the support for "set reverse-route"
which also has the option to add a tag and an AD.


With crytpo maps, the legacy command "reverse route" doesn't support tag and
AD options. Hence, if you need them, it should be done as following:




crypto dynamic-map mymap

 set security-association lifetime seconds 300

 set transform-set 3dessha

 set isakmp-profile profile1

 set reverse-route distance 20

 reverse-route




With regards
Kings
