6. (Optional for an IPv4 GRE Tunnel) Click the Route ACL name drop-down list and select the name of a
routing access control list (ACL) to attach a route ACL to inbound traffic on the L3 GRE tunnel interface.
When you associate a routing ACL to inbound traffic on a switch terminating a L3 GRE tunnel, that ACL can
forward traffic as normal, routetraffic to a nexthop router on a nexthop list, or redirect traffic over an L3
GRE tunnel or tunnel group. For more information on creating a routing ACL, see Creating a Firewall Policy
on page 376
7. (Optional for IPv4 or IPv6 GRETunnels) Select Enable Heartbeats to enable tunnel keepalive heartbeats.

9. Next, log into Switch-2 and navigate to Configuration>Network>IP>GRE Tunnels.
10.Highlight the line for the tunnel ID of interest and click Edit.
11.Enter the corresponding GRE tunnel values for this switch.
n to create an IPv4 L3 GRE tunnel, use the values for Switch-2 as shown in Figure 18.
n To create an IPv6 L3 GRE tunnel ure an IPv6 GRE tunnel , use the values for Switch-2 as shown in Figure
19.
12.(Optional for an IPv4 GRE Tunnel) Click the Route ACL name drop-down list and select the name of a

In the CLI
The following command examples configure an IPv4 Layer-3 GRE tunnel for IPv4 between two switches.
Referring to Figure 18, the following are the required configurations to create the IPv4 Layer-3 GRE tunnel
between switches named Switch-1 and Switch-2:
IPv4 Switch-1 Configuration
(Switch-1) (config) # interface tunnel 104
description “IPv4 L3 GRE 104"
tunnel mode gre ip
ip address 1.1.1.1 255.255.255.255
tunnel source vlan 10
tunnel destination 20.20.20.249
trusted
IPv4 Switch-2 Configuration
(Switch-2) (config) # interface tunnel 204
description “IPv4 L3 GRE 204"
tunnel mode gre ip
ip address 1.1.1.2 255.255.255.255
tunnel source vlan 20
tunnel destination 10.10.10.249
trusted
The following command example configures a Layer-3 GRE tunnel for IPv6:
IPv6 Switch-1 Configuration
(Switch-1) (config) # interface tunnel 106
description “IPv6 Layer-3 GRE 106"
tunnel mode gre ipv6
ip address 2001:1:2:1::1
tunnel source vlan 10
tunnel destination 2001:1:2:2020::1
trusted
