Applying an ACL or PBR to a tunnel interface on the SX-FI48GPP interface module

To apply an ACL or PBR policy to a tunnel interface on the SX-FI48GPP interface module, enter
commands such as the following:

NOTE
Configuration of tunnel loopback ports are not applicable on the SX-FI48GPP interface module.

Applying a PBR policy to a tunnel interface

device(config)# interface tunnel 1

device(config-tnif-1)# tunnel mode gre ip

device(config-tnif-1)# ip policy route-map test-route

Applying an ACL policy to a tunnel interface

device(config)# interface tunnel 1

device(config-tnif-1)# tunnel mode gre ip

device(config-tnif-1)# ip access-group 10 in

Configuring an IP address for a tunnel interface

An IP address sets a tunnel interface as an IP port and allows the configuration of Layer 3 protocols,
such as OSPF, BGP, and Multicast (PIM-DM and PIM-SM) on the port. Note that the subnet cannot
overlap other subnets configured on other routing interfaces, and both ends of the tunnel should be in
the same subnet.

To configure an IP address for a specified tunnel interface, enter commands such as the following.

device(config)# interface tunnel 1

device(config-tnif-1)# ip address 10.10.3.1/24

Syntax: [no] ip address ip-address

The ip-address is the IP address being configured for the specified tunnel interface.

Configuring a static route to a tunnel destination

If a route to the tunnel destination does not already exist on the tunnel source, create a static route
and set the route to go through the tunnel interface.

device(config)# ip route 131.108.5.0/24 10.0.8.1

device(config)# ip route 10.10.2.0/24 tunnel 1

Syntax: [no] ip route ip-address tunnel tunnel-ID

• The ip-address variable is the IP address of the tunnel interface.
• The tunnel-ID variable is a valid tunnel number or name.
