Viewing Statistics for GRE Tunnels
399
In this example, Router 1 establishes a GRE tunnel to Router 2 using a local router address of 172.16.17.18, a
remote router address of 172.19.20.21, and a remote subnet of 192.168.2.0/24.
NOTE
When connecting a Cisco router (in place of Router 1 in the previous example), the local router
address corresponds to the Cisco IOS
source
address and the remote router address corresponds to the
destination
address.
The cost of the GRE tunnel can also be set if another method of routing between Router 1 and Router 2 becomes
available. The packets will automatically flow through the lowest cost route.
Packets can also be restricted by specifying a local egress device, such as w1pp in the case of Router 1 in the
previous example.
