Assigning A Network Id To The Evi Tunnel; Specifying Extended Vlans On The Evi Tunnel - HP FlexFabric 12900 Series Configuration Manual

Step
3. Specify a source IP address
or interface for the tunnel.
4. Configure the EVI link
keepalive interval and the
maximum number of
keepalive transmissions.
5. (Optional.) Generate a GRE
key for tunneled packets
based on their VLAN IDs.

Assigning a network ID to the EVI tunnel

Assign the same network ID to the EVI tunnels of all edge devices in an EVI network.
On an edge device, the network ID assigned to an EVI tunnel must be unique.
To assign a network ID to an EVI tunnel:
Step
1. Enter system view.
2. Enter tunnel interface view.
3. Specify a network ID.

Specifying extended VLANs on the EVI tunnel

When configuring extended VLANs, follow these guidelines:
Command
source { ipv4-address |
interface-type interface-number }
keepalive [ seconds [ times ] ]
gre key vlan-id
Command
system-view
interface tunnel number
[ mode evi ]
evi network-id number
9
Remarks
By default, no source IP address or
source interface is specified for any
tunnel.
The source interface can be a Layer 3
Ethernet interface, Layer 3 aggregate
interface, VLAN interface, or Layer 3
loopback interface.
EVI uses the specified address or the
primary IP address of the specified
source interface as the source IP
address of tunneled packets on the
transport network.
EVI networks can share a tunnel
source IP address or interface.
By default, a keepalive packet is sent
every five seconds and the maximum
number of transmissions is two.
If no reply is received from the remote
end on an EVI link after the maximum
number of keepalive transmissions is
reached, the local end considers the
EVI link as having failed.
By default, EVI tunneled packets do
not contain a GRE key.
The GRE key setting must be the same
across an EVI network. Perform this
step if any remote edge devices
generate VLAN ID-based GRE keys
for EVI tunneled packets.
