Assigning A Network Id To The Evi Tunnel; Specifying Extended Vlans On The Evi Tunnel - H3C S12500 Series Configuration Manual

Step
3. Specify a source IPv4
address or interface for the
tunnel.
4. Configure the EVI link
keepalive interval and the
maximum number of
keepalive transmissions.

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 among all EVI tunnels.
To assign a network ID to an EVI tunnel:
Step
1. Enter system view.
2. Enter EVI 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 ] ]
Command
system-view
interface tunnel number
[ mode evi ]
evi network-id number
10
Remarks
By default, no source IP address or
source interface is specified for any
tunnel.
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.
The source interface can be a Layer 3
Ethernet interface, Layer 3 aggregate
interface, VLAN interface, or Layer 3
loopback interface.
EVI networks can share a tunnel
source IP address or interface.
IMPORTANT:
To avoid forwarding failure, do not
use a GRE tunnel interface or its IP
address (configure with the ip
address command in tunnel interface
view) as the source interface or IP
address of an EVI tunnel.
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.
