2. load-balancing flow [ src-dst-mac | src-dst-ip ]
DETAILED STEPS
Step 1 l2vpn
Example:
RP/0/RSP0/CPU0:router(config)# l2vpn
Enters the l2vpn configuration mode.
Step 2 load-balancing flow [ src-dst-mac | src-dst-ip ]
Example:
RP/0/RSP0/CPU0:router(config-l2vpn)# load-balancing flow src-dst-mac
Selects either the layer 2 or layer 3 address fields of the inner payload for hash function.
Configuring VXLAN destination UDP port
The UDP port numbers 4789 and 8472 are assigned to VXLAN and OTV respectively. Perform this task to
configure the destination UDP port number of the encapsulating VXLAN segment. This is an optional task
because, by default, the destination UDP port number of the encapsulating VXLAN datagram is set to 4789.
The destination UDP port number should be set to 8472 if the destination VTEP provides VXLAN support
using an OTV port.

Sets the destination UDP port number of the encapsulating VXLAN segment.
Configuration Example for Implementing Layer 2 VXLAN
Gateway
The following example shows layer 2 VXLAN gateway configuration on two Provider Edge (PE) routers,
R1 and R2, from a sample network topology that has the core network simplified as a bundle link connection
between the PE routers.
