i am trying to connect cisco 2911 router with noncisco routers (HP, TPlink) using site-to-site ipsec vpn with crypto-maps.
the problem is that vpn traffic shows "#send errors" if command "crypto isakmp identity dn" is used (we are using it for certificate based authentication for cisco vpn clients). when i delete the command, vpn works fine with noncisco devices.
please can you advice if there is any option on cisco ios to solve the problem.
