create vxlan-gpe tunnel
-------------------------------------------------------------------------
.. code-block:: console
create vxlan-gpe tunnel local <local-addr> {remote <remote-addr>|group <mcast-addr> <intf-name>} vni <nn> [next-ip4][next-ip6][next-ethernet][next-nsh] [encap-vrf-id <nn>] [decap-vrf-id <nn>] [del]
Add or delete a VXLAN-GPE Tunnel.
VXLAN-GPE provides the features needed to allow L2 bridge domains (BDs)
to span multiple servers. This is done by building an L2 overlay on
top of an L3 network underlay using VXLAN-GPE tunnels.
This makes it possible for servers to be co-located in the same data
center or be separated geographically as long as they are reachable
through the underlay L3 network.
You can refer to this kind of L2 overlay bridge domain as a VXLAN-GPE segment.
Example of how to create a VXLAN-GPE Tunnel:
.. code-block:: console
create vxlan-gpe tunnel local 10.0.3.1 remote 10.0.3.3 vni 13 encap-vrf-id 7
Example of how to delete a VXLAN-GPE Tunnel:
.. code-block:: console
create vxlan-gpe tunnel local 10.0.3.1 remote 10.0.3.3 vni 13 del

set interface ip vxlan-gpe-bypass
-------------------------------------------------------------------------
.. code-block:: console
set interface ip vxlan-gpe-bypass <interface> [del]
This command adds the 'ip4-vxlan-gpe-bypass' graph node for a given
interface. By adding the IPv4 vxlan-gpe-bypass graph node to an interface,
the node checks for and validate input vxlan_gpe packet and bypass
ip4-lookup, ip4-local, ip4-udp-lookup nodes to speedup vxlan_gpe packet
forwarding. This node will cause extra overhead to for non-vxlan_gpe
packets which is kept at a minimum.
Example of graph node before ip4-vxlan-gpe-bypass is enabled:
.. code-block:: console
show vlib graph ip4-vxlan-gpe-bypass
Name Next Previous
ip4-vxlan-gpe-bypass error-drop [0]
vxlan4-gpe-input [1]
ip4-lookup [2]
Example of how to enable ip4-vxlan-gpe-bypass on an interface:
.. code-block:: console
set interface ip vxlan-gpe-bypass GigabitEthernet2/0/0
Example of graph node after ip4-vxlan-gpe-bypass is enabled:
.. code-block:: console
show vlib graph ip4-vxlan-gpe-bypass

set interface ip6 vxlan-gpe-bypass
-------------------------------------------------------------------------
.. code-block:: console
set interface ip6 vxlan-gpe-bypass <interface> [del]
This command adds the 'ip6-vxlan-gpe-bypass' graph node for a given
interface. By adding the IPv6 vxlan-gpe-bypass graph node to an interface,
the node checks for and validate input vxlan_gpe packet and bypass
ip6-lookup, ip6-local, ip6-udp-lookup nodes to speedup vxlan_gpe packet
forwarding. This node will cause extra overhead to for non-vxlan_gpe packets
which is kept at a minimum.
