Configuring An Ipv4 Over Ipv6 Manual Tunnel - HPE FlexNetwork HSR6800 Configuration Manual

# Specify an IPv4 address for Serial 3/1/1, which is the physical interface of the tunnel.
[RouterB] interface serial 3/1/1
[RouterB-Serial3/1/1] ip address 3.1.1.1 255.255.255.0
[RouterB-Serial3/1/1] quit
# Create the IPv4 over IPv4 tunnel interface Tunnel 2.
[RouterB] interface tunnel 2 mode ipv4-ipv4
# Specify an IPv4 address for the tunnel interface.
[RouterB-Tunnel2] ip address 10.1.2.2 255.255.255.0
# Specify the IP address of Serial 3/1/1 as the source address for the tunnel interface.
[RouterB-Tunnel2] source 3.1.1.1
# Specify the IP address of Serial 3/1/0 on Router A as a destination address for the tunnel
interface.
[RouterB-Tunnel2] destination 2.1.1.1
[RouterB-Tunnel2] quit
# Configure a static route destined for IPv4 group 1 through the tunnel interface.
[RouterB] ip route-static 10.1.1.0 255.255.255.0 tunnel 2
Verifying the configuration
# Use the display interface tunnel command to display the status of the tunnel interfaces on Router
A and Router B. Verify that the tunnel interfaces are up. (Details not shown.)
# Verify that Router A and Router B can ping the IPv4 address of the peer interface GigabitEthernet
2/1/1. This example uses Router A.
[RouterA] ping -a 10.1.1.1 10.1.3.1

Configuring an IPv4 over IPv6 manual tunnel

Follow these guidelines when you configure an IPv4 over IPv6 manual tunnel:
•
The tunnel destination address specified on the local device must be identical with the tunnel
source address specified on the tunnel peer device.
•
Do not specify the same source and destination addresses for local tunnel interfaces in the
same tunnel mode.
•
To ensure correct packet forwarding, identify whether the destination IPv4 network and the IPv4
address of the local tunnel interface are on the same subnet. If they are not, configure a route
reaching the destination IPv4 network through the tunnel interface. You can configure the route
by using one of the following methods:
Configure a static route, and specify the local tunnel interface as the egress interface or
specify the IPv6 address of the peer tunnel interface as the next hop.
Enable a dynamic routing protocol on both tunnel interfaces to achieve the same purpose.
