RE: Basic Site-to-Site IPSec VPN based Narbik book

If you add the default route on each side then initiate an extended ping to
source from your loopback to the other loopback, your IPSEC tunnel will come
up and traffic between loopbacks will be encrypted.

Ryan, Why we need deault route because the peer is directly connected and
its reachable...

Even I add the default route....seems same situation... I can able to reach
the loopback due to the default route...but isnt my goal

Rack1R2#sh crypto isakmp sa
IPv4 Crypto ISAKMP SA
dst src state conn-id slot status

IPv6 Crypto ISAKMP SA
