What is a tunnel on a router?
An IP tunnel is an Internet Protocol (IP) network communications channel between two networks. IP tunnels are often used for connecting two disjoint IP networks that don’t have a native routing path to each other, via an underlying routable protocol across an intermediate transport network.
How do you set up a tunnel?
Step 2. Create the IPsec Tunnel on Location 1
- Log into the X-Series Firewall at Location 1.
- Go to the VPN > Site-to-Site VPN page.
- In the Site-to-Site IPSec Tunnels section, click Add.
- Enter a Name for the VPN tunnel.
- Configure the settings for Phase 1 and Phase 2.
- Specify the network settings:
Why are tunnels not straight?
It had to be curved, rather than straight, simply because the horses would bolt if they saw the light at the end of the tunnel. Nowadays horses and carts have been replaced by cars and lorries. In 1999 a crash, followed by a fire, in the Mont Blanc tunnel between France and Italy killed 39 people.
What is the use of tunnel?
Tunnels have many uses: for mining ores, for transportation—including road vehicles, trains, subways, and canals—and for conducting water and sewage.
How do you check the VPN tunnel status in a Cisco router?
From the Wired Client, browse to http://dcloud.cisco.com/ to access the Cisco dCloud UI and then log in with your Cisco.com credentials. Use the Bandwidth Test to verify that the port needed for VPN connectivity (TCP 443) is not blocked at your site. From the Wired Client, ping AD1 at 198.18.
What does tunnel-IPsec do on a Cisco router?
This module describes the configuration of Tunnel-IPSec interfaces on the Cisco CRS Router. Tunnel interfaces are virtual interfaces that provide encapsulation of arbitrary packets within another transport protocol. The Tunnel-IPSec interface provides secure communications over otherwise unprotected public routes.
What does a tunnel interface do in router?
Tunnel interfaces are virtual interfaces that provide encapsulation of arbitrary packets within another transport protocol. The Tunnel-IPSec interface provides secure communications over otherwise unprotected public routes. A virtual interface represents a logical packet switching entity within the router.
What are tunnel interfaces on Cisco IOS XR?
Configuring Tunnel Interfaces on Cisco IOS XR Software This module describes the configuration of Tunnel-IPSec interfaces on the Cisco CRS Router. Tunnel interfaces are virtual interfaces that provide encapsulation of arbitrary packets within another transport protocol. The Tunnel-IPSec interface provides secure communications over otherwise
How are tunneling techniques implemented in Cisco IOS?
This module describes the various types of tunneling techniques available using Cisco IOS software. Configuration details and examples are provided for the tunnel types that use physical or virtual interfaces. Many tunneling techniques are implemented using technology-specific commands, and links are provided to the appropriate technology modules.
