Configuring an EVI tunnel
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an EVI tunnel
interface and enter tunnel
interface view.
interface tunnel number mode evi
By default, no tunnel interface exists.
The endpoints of a tunnel must use the
same tunnel mode.
3. Specify a source IP address
or interface for the tunnel. source { ipv4-address |
interface-type interface-number }
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.
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. For more information
about GRE, see Layer 3—IP Services
Configuration Guide .
4. Configure the EVI link
keepalive interval and the
maximum number of
keepalive transmissions.
keepalive [ seconds [ times ] ]
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.
