Tunnel Group clarification

robbo79871

Hi, i would like to know what exactly the tunnel groups are used for and how they're "called" in VPN's etc...

Basically, i would like to know what the actual use of them are and what would happen if they weren't configured in the VPN process. Also, how are they actually "called" in terms of what activates them? I know you set them to the "peers" address, so is it the peers address when its triggered and contacted it automatically activates the tunnel group?

Sorry i am a bit new to configuring VPN's, i have most of the concepts down now, its just certain things that I'm not getting and these are pretty much the only ones left i need to figure out.

Thanks

Hello

 

reference below link

https://www.cisco.com/c/en/us/td/docs/security/asa/asa-cli-reference/T-Z/asa-command-ref-T-Z/m_tl-tz.htmln

name define as below

 

name

Specifies the name of the tunnel group. This can be any string you choose. If the name is an IP address, it is usually the IP address of the peer.

For LAN-to-LAN connections, the ASA attempts to select a tunnel group for a connection by matching the peer address specified in the crypto map to a tunnel group of the same name.

 

 

if you would like to use name, you may need to use isakmp.
