configuration for cisco router to use VPN ?

I didnt see any VPN configuration on either of the Routers.

I am going to list the steps to set one up. just repeat the process on the other router, just switching IP's

1.) R1(config)# crypto isakmp enable

2.) R1(config)# crypto isakmp policy 10
R1(config-isakmp)# authentication pre-share
R1(config-isakmp)# encryption aes 256
R1(config-isakmp)# hash sha
R1(config-isakmp)# group 5
R1(config-isakmp)# lifetime 3600

3.) R1(config)# crypto isakmp key PASSWORD address (IP of other router)

4.) R1(config)# crypto ipsec transform-set 50 esp-aes 256 esp-sha-hmac ah-sha-hmac

5.) R1(config)# access-list 101 permit ip (LOCAL LAN) (REMOTE LAN)

6.) R1(config)# crypto map NAME 10 ipsec-isakmp

7.) R1(config-crypto-map)# match address 101

8.) R1(config-crypto-map)# set peer (IP OF R2)
R1(config-crypto-map)# set pfs group5
R1(config-crypto-map)# set transform-set 50

9.)on the outside interface apply the crypto map
   R1(config-if)# crypto map NAME
 

Dear equarando
" crypto " not in my router command ? Im using 2800 cisco router

You prolly are not running a version of the IOS that supports IPSEC VPN's

Dear equarando

I add this Lines in R1




R1(config)#router bgp 65360
R1(config-router)#network 172.15.0.0 255.255.0.0
!
Then I connect My PC to Router R1  throw interface F0/1
Then I ping all this IP
172.15.5.1              OK (Replay)
172.31.106.206      OK (Replay)
172.31.106.205      OK (Replay)
172.31.106.129      OK (Replay)
172.31.106.130      OK (Replay)
172.28.1.1              NO (Request Time out)

now I add another line

R1(config)#router bgp 65360
R1(config-router)#red con

and the result is

Then I connect My PC to Router R1  throw interface F0/1
Then I ping all this IP
172.15.5.1              OK (Replay)
172.31.106.206      OK (Replay)
172.31.106.205      OK (Replay)
172.31.106.129      OK (Replay)
172.31.106.130      OK (Replay)
172.28.1.1              OK (Replay)
